聚合物材料的降解与化学反应，其中分子链被切断称为腐蚀。本文根据实验结果，综述了树脂和玻璃钢在几种水溶液中的腐蚀行为、形式和机理。腐蚀有三种类型：表面反应型、腐蚀层形成型和渗透型。每种形式都取决于树脂的化学结构、树脂与环境之间的反应性以及环境介质进入树脂的扩散率。金属腐蚀速率的概念甚至可以应用于每种腐蚀形式的塑料和纤维增强塑料。
The degradation of polymeric materials with chemical reaction in which the molecular chains is cut is called corrosion. In this paper the behavior, the forms and mechanisms of corrosion of resins and GFRP (glass fiber reinforced plastics) under several aqueous solutions are reviewed based on our experiments. Three types of corrosion exist: the surface reaction type, the corroded layer forming type and the penetration type. Each form was determined by the chemical structures of the resin, the reactivity between resins and environments, and also the diffusivity of environmental media into the resins. The concept of the corrosion rate of metals could be applied even in plastics and fiber reinforced plastics for each corrosion form.
