Effects of ion‐exchange fillers on durability of the polymer matrix of composites

Abstract Glass fiber composites are susceptible to alkali attack on both glass fibers and the polymer matrix. Cation‐exchange fillers were introduced into the polymer matrix of composites to neutralize the alkaline solutions diffusing through the polymer system, and thus enhance the chemical resistance of composites. Experiments were conducted on isophthalic polyester and vinylester polymer systems incorporating different dosages of ion‐exchange fillers. Accelerated aging effects on these polymer systems validated the positive effects of ion exchangers on durability characteristics. POLYM. COMPOS. 26:679–683, 2005. © 2005 Society of Plastics Engineers
