Chronological change of properties on composites was measured up to 1,000 days immersed in food simulating solutions, such as 20% alcohol solution, citric acid solution, salad oil and distillled water.The absorption rate of composites was almost same in aqueous solutions during hundreds days, however after 1,000 days there were significant differences in the absorption rate.By the immersion in these solutions, the resin matrix of composites was plasticized by the of solutions absorbed, and the flexural strength after 100 days on composites was prone to be increased especially in salad oil. Thereafter the mechanical properties of composites were decreased by the debonding of fille/matrix interface in aqueous solutions.The color differences of the composites were measured in the solutions absorbed and the dried after immersion. From the results it was also suggested the debonding of filler matrix interface in the composites.

在20%乙醇溶液、柠檬酸溶液、色拉油和蒸馏水等食品模拟溶液中浸泡1,000天后，复合材料的吸水率随时间的变化基本相同，但1,000天后，复合材料的吸水率有明显差异。复合材料的树脂基体被吸收的溶液增塑，复合材料100天后的弯曲强度增加，尤其是在色拉油中。在水溶液中，复合材料的力学性能因填料/基体界面的脱粘而降低。结果还表明，复合材料中存在填料/基体界面脱粘现象。
