摘要：

Environmental stress corrosion cracking (ESC) behavior of different polyamides (PA) without and with short and glass fiber mat reinforcements was studied in air, water and diluted sulfuric acid and compared. Whereas the neat polymers and their short glass fiber reinforced versions failed by crack growth, the breakdown of the glass mat reinforced polyamide block copolymer (NBC) depended on the corrosion loading history, i.e. on the immersing time. The ESC response of the systems studied was analysed and summarized schematically indicating the effects of matrix structure, type and amount of the reinforcement and environment. Characteristic failure events were also revealed and included in related models. Guide-lines for further material improvements were deduced.
