Natural Aging Test for CF3011/BA9916-II Composite in Marine Environment
Abstract: A form of static coupon following the boat was developed to carry the natural aging test for CF3011/BA9916-II composite in marine environment, and the weather resistance of composite in marine climate was studied. The changes of the morphology of the composite were observed, the changes of the quality ,tensile strength and interlaminar shear strength for specimen were analyzed, and the aging regulation was studied combining with the mechanism of hygrothermal aging for carbon fiber epoxy composite. The test results showed that with the aging time increasing, the moisture absorption of the composite increased, the mechanical strength decreased , and the plastic behavior of the material was showed.
