摘要
Abstract
Continuous glass fiber reinforced polypropylene (PP) prepreg is used to fabricate composite laminates.Continuous glass fiber reinforced PP composites are subjected to normal temperature,60 ℃ and 80 ℃ brine immersion experiments by artificial accelerated aging method.The flexural strength and performance degradation of the composite are investigated with aging time,aging temperature and other coefficients.The results show that the trend of moisture absorption was in accordance with Fick's spreads at the beginning of aging,and the degree of aging was proportional to time and temperature.The aging degree of the samples under different environmental conditions were examined by scanning electron microscopy (SEM).With the increase of aging temperature and time,the interface corrosion increases between the reinforcing fiber and the resin matrix.关键词
