Microbial Degradation of Fiber Reinforced Polymer Composites
Abstract
Two fiber reinforced polymer composites were examined for susceptibility to microbial degradation. Composites, resins and fibers were exposed to sulfur/iron-oxidizing, calcareous-depositing, ammonium-producing, hydrogen-producing and sulfate-reducing bacteria (SRB). Surfaces were uniformly colonized in all cases. Epoxy and vinyl ester neat resins, carbon fibers and epoxy composites were not adversely affected by microbial species. SRB degraded the organic surfactant on glass fibers and preferentially colonized fiber-vinyl ester interfaces. Hydrogen-producing bacteria appeared to disrupt bonding between fibers and vinyl ester resin and to penetrate the resin at the interface.
