The surface degradation of composite resins caused by accelerated aging was studied. Accelerated aging for 900 hours caused erosion of the resin matrices and exposure of filler particles. Differences in surface profiles after aging suggest that the materials eroded at different rates. Accelerated aging may model erosive wear of composites.
研究了加速老化导致的复合树脂表面降解情况。900小时的加速老化导致树脂基体出现侵蚀以及填料颗粒暴露。老化后表面轮廓的差异表明材料以不同速率被侵蚀。加速老化可模拟复合材料的侵蚀性磨损。
