Research Mechanical Test of Accelerated Aging Method for Carbon Fiber Reinforced Polymer Composites

Abstract

It is an important engineering problem that affected by the environmental factors, the performance of aircraft structure of carbon fiber reinforced polymer (CFRP) under the Marine environment has depredated; and it is an important means of analysis of CFRP material degradation by accelerating aging mechanics experiments under laboratory conditions. First of all, a laboratory accelerated aging spectrum of some sea area is compiled under the foundation of the sea temperature and humidity spectrum ultraviolet irradiation, and with the principle of damp and hot effection is equal to light endowment for CFRP sheet damage failure; Secondly, combining with this accelerated aging spectrum, the accelerated aging experiments have been done for the one-way and the single experiment conduct; Finally, the experimental results for hygroscopic rate and morphology have been analysis. It is showed that the accelerated aging 1a later, the moisture absorption rate is increasing, and the macro morphology changed obviously, the moisture absorption affection is most obvious by 0°, followed by 90°, the anti-aging performance is best by 45°.
