Abstract
The utility model relates to a composite fiber material, in particular to a high-temperature resistant anti-ultraviolet composite fiber material which is a high-performance fiber material comprising a PBO (polybenzoxazole) fiber sandwich layer and a polyimide outer layer. The high-temperature resistant anti-ultraviolet composite fiber material adopts a coating structure. The coating structure comprises the PBO fiber sandwich layer and the polyimide outer layer, wherein the polyimide outer layer is coated on the PBO fiber sandwich layer. The high-performance fiber material can be used as a textile fiber composite material for making a rope, a net and woven fabric used in special environments, so as to remarkably improve the heat resistance and the anti-ultraviolet performance while ensuring the fine performance of the PBO fiber. Therefore, the high-performance fiber material can be extensively applied to the fields of the aeronautics and astronautics industry, the petrochemical industry, the power industry and the like, and has a favorable protective performance and a favorable protective effect.
Description
Technical field
The utility model relates to a kind of compound fibrous material, particularly relates to a kind of high temperature resistant uvioresistant composite fibre with high temperature resistant uvioresistant performance, specifically relates to the outer high performance fibre material of forming of pbo fiber sandwich layer and a kind of polyimides
Background technology
Polyparaphenylene Ben Bing Er oxazole fiber (be called for short pbo fiber, down with) is in the present high-performance fiber field, and one of high-performance fiber that combination property is the most excellent has excellent mechanical property, heat-resisting, fire resistance, solvent resistance etc.As being example with pbo fiber
; Its TENSILE STRENGTH is 5.8GPa; Stretch modulus is 300GPa; Be respectively the twice of PPTA fiber, Zylon also has excellent heat endurance (heat decomposition temperature is up to 650 ℃) and anti-flammability (LOI=68).Pbo fiber has very wide application prospect and important use to be worth at aspects such as Aero-Space, protective materials, national defense and military, sports equipments, the irreplaceable effect of other material is arranged.
Though pbo fiber has mechanical property and heat resistance preferably, pbo fiber is under UV-irradiation, and decline by a relatively large margin can appear in the mechanical property of fiber, and this greatly influences or has limited the application of pbo fiber in advanced field of compound material.For this reason, how to produce uvioresistant pbo fiber composite and become the key issue that letter need solve.
