sort mechanics
1.Liquid crystal macromolecule PBO (poly-p-phenylene-benzobisoxazole) fiber, a kind of polymer material with high strengh, high modulus and excellent chemical resistance, has a vast applied foreground in heatproof materials and strengthen materials with mechanics characteristic. It is seen as a new sort of super fiber among many complex materials with advanced construction in aviation and spaceflight after Kevlar fiber is found.
