What are the characteristics of aviation plastics 5, what are the characteristics of aviation plasti

I don't know what exactly you're referring to by aerospace plastics. At present, the materials used in aircraft include ceramic materials in addition to traditional metal (alloy) materials.

Polymer materials, composite materials, high-temperature structural materials. What you are referring to should belong to composite materials, modern composite materials are divided into three categories according to the type: polymer based on organic molecules, metal based and inorganic non-metal base.

Among them, the polymer matrix is divided into resin matrix and rubber elastic matrix; Metal bases are divided into aluminum base, titanium base, magnesium base, nickel base, intermetallic compound base, etc.; Inorganic non-metallic bases are further divided into ceramic bases, glass bases and cement bases.

Composites improve or overcome the weaknesses of the constituent materials and can be optimally designed according to the structure and force of the part, so as to obtain new superior properties. It is fundamentally different from the simple mixing of general materials, and it has the following performance characteristics:

1.Specific strength.

and high specific modulus.

2.Good fatigue resistance.

3.Good vibration damping performance.

4.Good performance at high temperatures.

5,。High fracture safety.

6.Other special features. For example: coefficient of friction.

It is much lower than the polymer material itself, with good wear resistance, corrosion resistance and process performance, high radiation resistance, creep performance and special optical, electrical, magnetic and other properties.

The above content is excerpted from our book "Aviation Materials and Technology", I hope to help you, for the sake of hard work, hope.

Super hard, some even meet the requirements of steel, high fire level, can not be burned with a lighter, ordinary materials are burned with an open flame. There are many kinds. This is just one of my understandings.

<>1. Aviation board is also called aviation PC board, aviation PC board is also called aviation PC endurance board (also known as polycarbonate solid board, bulletproof glass, solid board, aviation PC resin board) is made of high-performance engineering plastics, polycarbonate or polycarbonate (PC).

2. Aviation plate is made of engineering plastics with high performance, such as polycarbonate or polycarbonate. Aviation plate, also known as aviation Zhengju PC endurance board, also known as polycarbonate solid board, bulletproof glass, aviation PC resin board, the main raw material is PC plastic material. It can be applied to the interior and exterior decoration of walls, roofs, screens and other buildings, its strength is super high, even more than the reinforced glass and acrylic board, and the toughness, security, anti-theft and bulletproof function is excellent, and the same transparency as glass.

As we all know, plastic materials have played a vital role in the history of spaceflight, not only in space vehicles, but also in enabling astronauts to observe their surroundings, breathe oxygen, and move comfortably in orbit. Global Plasticizer believes that without plastic, space exploration may not have reached the heights it is today.

Space helmets and shades.

When you think of the first astronaut visiting the moon, you might think of images of helmets in fluffy space suits and shiny visors. Those helmets and masks are made of molded plastic that can withstand the roughness of the space.

Thanks to these plastics, astronauts are able to clearly see their surroundings without losing oxygen or being infiltrated into their clothing by debris substances. Most of the protective devices worn by astronauts are also made of plastic because of its flexibility and reliable functionality.

Softer spacecraft seats.

To eliminate the effects of landing, NASA developed bubble foam, also known as memory foam, for spacecraft seats. This open polyurethane silicone makes it easier for astronauts to travel to and from space without getting injured or feeling uncomfortable when re-entering.

It is now used in mattresses and high-end furniture to make it easier for people to sleep, relax and unwind. The protective properties of plastics make them one of the most useful materials for promoting astronautics and exploration.

Radiation protection in space.

According to The News, in the early stages of the space program, aluminum was massively used in the construction of spacecraft. However, aluminum does not have the same shielding and protection capabilities as some plastics in blocking cosmic radiation. This radiation is the main obstacle to the extension of space and habitation.

And plastics are already helping scientists create short- and medium-term solutions to protect astronauts from harmful light. The net benefit of plastic parts is safer space travel and longer time in orbit for astronauts.

Sky lenses. The space is full of all kinds of debris, and the appearance of anti-scratch lenses effectively avoids such dangers. A plastic coating is applied to the lenses to make them scratch-resistant, which can better protect the astronauts.

Without a reliable way to observe their surroundings, astronauts will be at a serious disadvantage.

Plastic supplies. Plastics are generally lighter than other materials used to make spacecraft. The use of lighter materials results in lower ground costs for rockets and spacecraft and less fuel consumption.

Plastic seals, floors, seats, and dashboards are among the plastic parts that make the spacecraft more light and flexible. Lighter spacecraft are also easier to move and store, which is a significant cost savings for space agencies.

Plastics are indispensable for the tools, equipment, and transportation needed to explore outer space. With the development of the economy and the progress of science and technology, plastics may continue to enable mankind to take a new step in exploring the depths of outer space. The research and development of these products are inseparable from the excellent characteristics of plastics.

Aircraft made of plastic have already been successfully test-flown Replacing part of the metal with new engineering plastics to make aviation parts can reduce the weight of the aircraft, the production cost is low, the insulation performance is good, and the corrosion resistance is higher than that of general metal materials. For example, plastic components of the same strength can weigh about half as much as aluminum alloy components, and using them to build aircraft of the same size can reduce fuel consumption, increase flight range and improve aircraft flight performance.

The development of new material technology has led to the emergence of new engineering plastics, and the strength of some plastic materials has increased to 3840 kilograms.

i.e. aircraft made of plastic. The fuselage of this kind of aircraft is all made of plastic, which greatly reduces the weight of the aircraft, and the production cost is low, the insulation performance is good, and the corrosion resistance is strong. There is a plastic airplane in the United States, which weighs only one ton, and it weighs 45 percent less and saves 50 percent of gasoline than its metal sock-old counterparts. Plane.
