Chapter 250 Development of Materials

However, we must keep going no matter how difficult it is. Laser is a very important branch of science in the future and one of the core technologies in semiconductor production.

For example, the DUV light source in the main world is an excimer laser, and EU light is produced by high-energy laser bombarding metal tin droplets.

These are all things related to lasers. Any important advance in the development of semiconductors is inseparable from the development of these basic sciences, and the most basic raw materials of these basic sciences are indispensable.

Just like aircraft engines, when they evolved from propellers to jets, the requirements for materials instantly leapt forward by an era.

For today's aviation engines, Ren Zhong is already producing a world-class Merlin 1650-V12 engine.

More than 20 P51D Mustang fighter jets have even been produced to supplement the ground and air defense forces.

The monthly production capacity gradually increased from the original 2 aircraft to about 10 aircraft.

The Rogue Hawk's P-51D Mustang fighter also adopted many innovative technologies, including the first use of laminar flow wings. In addition, engineers also used plastics on many traditional glass and metal parts. By using plastic parts, they reduced the weight of the aircraft by more than 400 pounds, making the aircraft very agile.

By using high-shear rivets, the Mustang fighter was reduced by more than 400 pounds, enough to fit into the 321.76-liter fuel tank, because 321.76-liter fuel tank weighs almost exactly 400 pounds.

Lightweight materials also help increase production rates. For example, plastic instrument vacuum manifolds can be produced at a rate of two per minute.

When made from aluminum, it takes nearly an hour of machining time to create one unit.

These innovative tasks are being accomplished with great effort. For example, engineering plastics are now being produced, which can replace many non-load-bearing structural parts on fighter jets. Compared with metal parts, plastic parts can be processed more quickly and can be quickly formed through heating and machinery.

In addition, the industrial manufacturing process of methyl ester has now completed research and entered production, which means that plexiglass manufacturing is about to enter mass production. For fighter aircraft cabin covers, such materials will reduce the large-scale use of glass, increase the life of the cabin cover, and reduce weight.

The current version of the P51D is actually different from the original Rogue Eagle, and many materials were used instead of each other.

Therefore, in terms of production capacity, the aviation manufacturing plants in the border areas are still far behind the peak production capacity of 570 Rogue Eagles per month at the North American factory.

However, as the materials mature, the production and installation efficiency of many components will be greatly improved.

According to estimates, after the production process and materials are optimized in the future, the production capacity of P51D is expected to increase to 50 aircraft per month.

This is basically the limit of the production capacity of the 10,000-ton hydraulic press.

If further improvement is required, a second 10,000-ton hydraulic press will need to be developed.

This task is now assigned to Taiyuan’s Second Heavy Machinery Plant.

The construction of the second 10,000-ton hydraulic press is already underway.

For this kind of large-scale mechanical equipment, not only is the investment huge, but the key construction period is also relatively long, and the task is somewhat overwhelming.

However, for heavy machinery production, this equipment is difficult to avoid and Ren Zhong has to grit his teeth and invest in it.

The manufacturing expansion of mature equipment is no longer within Ren Zhong's concern. He only needs to put forward indicator requirements.

Now Renzhong's focus has begun to shift from steel alloys to the development of non-steel materials, especially engineering plastics.

As for engineering plastics, it has many branches. The first one introduced by Ren Zhong is polyamide (nylon). This engineering plastic with relatively simple production has a wide range of uses. Typical products include pump impellers, fan blades, valve seats, bushings, bearings, various instrument panels, automotive electrical instruments, hot and cold air control valves and other parts. These are industrial. In fact, it is also widely used in clothing. Nylon fiber has excellent elasticity and stretchability, so nylon sportswear has excellent adaptability and comfort. As for black silk, it is well known, but the current production capacity is limited, and Ren Zhong has not yet considered the application of clothing.
The second type introduced is polyoxymethylene (POM). This plastic has the hardness, strength and rigidity similar to metals. It has good self-lubrication and good fatigue resistance in a wide range of temperature and humidity. It can replace zinc, brass, aluminum and steel to make many parts. Since its advent in the main world, POM has been widely used in electronics, machinery, instrumentation, daily light industry, automobiles, building materials, agriculture and other fields. In this time and space, it is basically a product of the laboratory. In terms of aspects, this product was synthesized in 1939, and DuPont applied for a patent in 1942, but large-scale mass production did not begin until 1959 to overcome many production process problems.

However, since Ren Zhong was seriously short of metals such as zinc, brass, and aluminum, he tried to buy a complete factory production process from the 70s for this plastic production process from the main world. Although it was outdated compared to the main world, Ren Zhong could use the technology and equipment of the Bright Sword world to replicate this production process. If it was a new process from the s or s, some equipment could not be found or manufactured in the Bright Sword world.

Ren Zhong chose polycarbonate (PC, plexiglass) for the third choice. This plastic also has similar strength to non-ferrous metals, and at the same time has both ductility and toughness, excellent transparency, and can be colored in any way. It is the best substitute for glass and is widely used in transparent protective panels, lighting glass, high-rise building glass, car reflectors, windshield panels, aircraft cockpit glass, etc. At present, of course, the most important is the aircraft cockpit, which is basically a rigid demand product. In terms of discovery and synthesis, this product was also discovered in the 30s and was patented in 1941. However, due to the complex mass production process, it was not until 1960 that industrial mass production really began. For Ren Zhong, it was not difficult to find a production line at the level of the 70s. He spent more than yuan to get a real full set of industrial mass production design. The more troublesome thing is that most of the production equipment needs to be built by himself. This delayed the mass production of PC a little. We have just completed the initial mass production of a production line and produced the first batch of PC materials. Judging from the first engine cover produced, it is more rounded than the glass engine cover, has less air resistance and a more streamlined shape.

These engineering plastics are indispensable for the heavy-duty industrialization.

But it is far from enough. Next, polyphenylene sulfide (PPS), a material with stable properties and good insulation, is most widely used in automotive parts, mainly used in automotive igniters, sensors, connectors, thermostats, carburetors, carburetors, IGBT modules, IC regulators, temperature regulators, gear boxes, water valves, water tank water chambers, heater brackets, bearing brackets, seat bases, oil pan screws, lampshades, bumpers, automotive generator coil skeletons and brackets, exhaust systems, and reflectors and lamp holders. It can replace metal to make exhaust pipe circulation valves and water pump impellers, pneumatic signal regulators, etc.

Secondly, PPS materials are used in electronic appliances, accounting for about 30%, mainly in microelectronic component packaging, connectors, wiring connectors, IC sockets, coil skeletons, brush brackets, motor housings, electromagnetic adjustment disks, TV high-frequency head shafts, relays, fine-tuning capacitors, capacitor housings, rotor insulation components, fuse holders, tape recorders, magnetic therapy devices and other parts.

Finally, mechanical and chemical industry: used as bearings, pumps, valves, pistons, precision gears, acid and alkali resistant valve pipes, pipe fittings, valves, gaskets and submersible pumps or impellers and other corrosion-resistant parts.

Polybutylene terephthalate (PBT) has high insulation and temperature resistance. As one of the five general engineering plastics, it is mainly used in PBT modification, PBT wire drawing, film drawing, PBT optical fiber sheathing and other fields. After enhanced modification, it can be widely used in automobile manufacturing, electronic and electrical, instrumentation, lighting appliances, home appliances, textiles and other industrial fields.

It can be said that the introduction of these engineering plastics in this era has all played a revolutionary role.

Apart from building an engineering plastic chemical plant in the border area, Ren Zhong does not want to spread these technologies now. He will wait until there is a good external environment before registering patents to promote these technologies for global applications. You know, the application range of these engineering plastics is very wide, and their future business prospects are so great that it is unimaginable for people today.

Many of the things that Ren Zhong brought over were brand new patented technologies in this world.

Therefore, this engineering plastic chemical plant was set up near the main body of the Dawn Research Institute, and is now just beginning to expand its production scale and production lines.

Although the transportation conditions in the border areas are slightly worse.

But compared to keeping secrets, Ren Zhong would rather endure these troubles.

After all, the Dawn Research Institute's border region headquarters is now a strictly regulated confidential unit with the highest level of security protection and confidentiality requirements in the border region.

There is still a guard team of hundreds of people there, and each person is required to have a pass to enter and exit. Most workers live independently in the family quarters provided by the factory and do not have much contact with the outside world.

Just like a complete closed little society, at this stage, people still have a strong sense of mission and have no objection to this kind of life.

As for the top-secret rocket/missile and peace bomb research departments, for the researchers, they are almost isolated from the outside world. In fact, each of them is very self-conscious.

Knowing that this information is related to the rise and fall of the nation, in order to avoid leaking the secrets, they would rather move to the desert area and become isolated!
Therefore, after the Japanese, Guo Su, and other spies attacked the Yanjiao Japanese airport for the second time in the border area, they tried their best to get the message across, but did not gain much.

Including many evil hands that reached out to the Dawn Research Institute, most of them were cut off. According to confidentiality conditions and review requirements, this part of the work was jointly guaranteed by the 8th Guard Regiment and the security department of the Dawn Research Institute. Their superior was the border region's general staff, directly under the command of Staff Officer Ye.

Under such advanced security protection, the secrets of the Dawn Institute are preserved to the greatest extent.

Although some information was inevitably leaked, this was the least amount of information leaked for the secrets of the Dawn Institute.

In addition to the development of non-metallic materials, the development of nickel-based alloys with high temperature strength has now achieved certain results in the laboratory.

Ren Zhong wanted to buy the first high-temperature strength nickel-based alloy invented by John Bull in the early 40s, which was successfully developed by adding a small amount of aluminum and titanium to the 80Ni-20Cr alloy. It can withstand temperatures of almost 700°C, which is a necessary material for jet engines. At present, the laboratory has achieved crystal synthesis, but in terms of processing technology, the papers and related methods obtained have not been verified.

For Ren Zhong, this is an opportunity to overtake others. As long as the materials are solved, the jet engine will be stable. At least for Ren Zhong, it is not difficult to get the technical data of our first jet engine, the WP-5 engine, because he can directly find the technical data of its original BK-1φ engine for imitation.

This is our first domestically produced jet engine in the main world. It is a centrifugal, single-rotor, afterburner aircraft engine, suitable for our first generation jet fighter J-5 (MiG-17). For the current stage, this is enough to defeat all opponents.

Combined with the radar data obtained from the Rogue Eagle, the two together, if not invincible, are at least the ceiling at this stage.
