Full helmet material, ABS FRP carbon fiber basalt, which is the best quality??

Hello, ABS engineering plastics is PC ABS (engineering plastic alloy), the Chinese name in the chemical industry is plastic alloy, the reason why it is named PC ABS, because this material has both excellent heat and weather resistance, dimensional stability and impact resistance of PC resin, and has excellent processing fluidity of ABS resin. Therefore, it is used in thin-walled and complex-shaped products to maintain its excellent properties, as well as to maintain the formability of plastic and a material composed of esters.

2. FRP is a new type of composite material developed in the early 20th century, which has many advantages such as light weight, high strength, anti-corrosion, heat preservation, insulation, sound insulation and so on. The earliest composite material to appear was fiberglass, which has nothing to do with steel. There is no iron in FRP at all, and it is not a composite of glass and steel.

In fact, FRP is a material made of glass fiber composite with one or several thermosetting or thermoplastic resins, such as phenolic resins, epoxy resins, polyester resins, polyimide resins, etc.

3. Carbon fiber is a fibrous carbon material. It is a new type of material with greater strength than steel, smaller density than aluminum, more corrosion resistance than stainless steel, higher temperature resistance than heat-resistant steel, and electrical conductivity like copper, with many valuable electrical, thermal and mechanical properties. Aircraft made of composite materials made of carbon fiber and plastic are not only lightweight, but also consume less power, have high thrust and less noise; The use of carbon fiber to make the disk of the computer can improve the storage capacity and computing speed of the computer; Carbon fiber reinforced plastics are used to make spacecraft such as satellites and rockets, which have high mechanical strength and low mass, which can save a lot of fuel.

Definitely carbon fiber is the best, ** is also very expensive, and generally the good ones are more than 1000.

The carbon fiber one should be better. Because carbon fiber is stronger than glass fiber.

ABS resin is one of the five major synthetic resins, its impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties are excellent, but also has the characteristics of easy processing, stable product size, good surface gloss, easy to paint, coloring, can also be surface spraying metal, electroplating, welding, hot pressing and bonding and other secondary processing, widely used in machinery, automobiles, electronic appliances, instrumentation, textiles and construction and other industrial fields, is a widely used thermoplastic engineering plastics.

Composite materials are materials with new properties composed of two or more materials with different properties through physical or chemical methods on a macroscopic basis. Various materials complement each other in terms of performance, resulting in a synergistic effect, so that the comprehensive performance of composite materials is better than that of the original materials and meets various requirements. The matrix materials of composite materials are divided into two categories: metal and non-metal.

Metal substrates are commonly used in aluminum, magnesium, copper, titanium and their alloys. Non-metallic matrices mainly include synthetic resins, rubber, ceramics, graphite, carbon, etc. Reinforcement materials mainly include glass fiber, carbon fiber, boron fiber, aramid fiber, silicon carbide fiber, asbestos fiber, whisker, metal wire and hard fine particles.

Glass fiber reinforced plastic (FRP), also known as GRP, is a fiber-reinforced plastic, which generally refers to a matrix of unsaturated polyester, epoxy resin and phenolic resin reinforced with glass fiber. Reinforced plastics with glass fiber or its products as reinforcing materials are called glass fiber reinforced plastics, or glass fiber reinforced plastics. Due to the different types of resins used, it is known as polyester FRP, epoxy FRP and phenolic FRP.

Light and hard, non-conductive, high mechanical strength, less utilization, corrosion resistance. It can be used instead of steel to make machine parts and shells of automobiles and ships.

Carbon fiber, as the name suggests, is a new generation of reinforcing fibers that not only have the inherent intrinsic properties of carbon materials, but also have the soft processability of textile fibers. Compared with conventional glass fiber (GF), Young's modulus is more than 3 times that; Compared with Kevlar fiber (KF-49), it not only has about twice the Young's modulus, but also does not dissolve or swell in organic solvents, acids and alkalis, and has outstanding corrosion resistance. In 1981, some scholars soaked Pan-based CF in a strong alkali NaOH solution, and more than 30 years have passed, and it still maintains its fibrous form.

Difference: Carbon fiber material is the material with the highest mass-strength ratio. Materials can be distinguished according to the cross-section, and the specific performance can not be distinguished by the naked eye, and can only be tested by destructive tests.

Among them, ABS is anisotropic, FRP and carbon fiber composites are anisotropic, and the tensile strength in the fiber direction is the highest.

ABS belongs to thermoplastic materials, FRP is the so-called composite material, a large part of the helmet is carbon fiber prepreg epoxy resin high-pressure and high-temperature molding, there are also glass fiber and unsaturated resin hot press molding, the strength needless to say, of course, is the best carbon fiber, ** is also the most expensive.
