Abstract
Composite material has been widely used in various industries because of its superior properties. But when used in harsh environment the composite material is susceptible to aging under the influence of UV radiation, water, temperature, humidity and other natural environmental medium. To evaluate the environmental adaptability of composite material, exposed 3238A/CCF300 in marine atmospheric environment for 3 year. The results show that the morphology exhibit brightness enhancement and surface resin decomposition. And the mechanical properties including 90° tensile strength, 0° compressive strength, bending strength, shear strength have all decline, amongst which the 90° tensile strength declines 55.4%, is most sensitive to marine atmospheric environment. Finally analyses the failure mechanism of 3238A/CCF300 due to the combination of heat-humidity aging and photo-degradation process.
