Application Analysis of Polyethylene Sheet in Aerospace

Polyethylene board is the plastic king of plastic products. Polyethylene board is an engineering plastic with superior performance. Its characteristics are superior to other plastic products. It is the plastic king of plastic products. Very low friction coefficient, good self-lubricating performance, excellent low temperature resistance, chemical corrosion resistance, non-toxic, five flavors and other properties are incomparable to other plastics.

Polyethylene sheet has the advantage of being light and soft, and its bulletproof effect is better than that of aramid fiber. It has now become the main fiber occupying the US bulletproof vest market. In addition, the specific impact load value U/p of ultra-high molecular weight polyethylene fiber composites is 10 times that of steel, and more than twice that of glass fibers and aramid fibers. Bulletproof and anti-riot helmets made of this fiber-reinforced resin composite abroad have become substitutes for steel helmets and aramid fiber-reinforced composite helmets.

The polyethylene sheet fiber composite material is light, high-strength and has good impact resistance, and is suitable for wingtip structures of various aircraft, spacecraft structures and buoy aircraft. Polyethylene sheet fibers can also be used as deceleration parachutes for space shuttle landing and ropes for hanging heavy objects on aircraft, replacing traditional steel cables and synthetic fiber ropes, and its development speed is extremely rapid.

The excellent low temperature resistance of polyethylene sheets can be used as low temperature resistant components in the nuclear industry; the excellent hygienic and non-toxic properties can be used in food and hygiene industries; vacuum box panels, dehydration plates, scrapers, sealing strips, etc. can be used in the paper industry; Utilizing wear resistance, impact resistance, non-sticking, hygienic and non-toxic, it can be used in beverage and food machinery, etc.
