Reduction of tensile strength was demonstrated for carbon fiber-reinforced epoxy resin composite strips after exposure to sulfate-reducing bacteria in batch culture. Composite strips were maintained in a stressed condition in 3- and 4-point bend fixtures before and during exposure. Exposed surfaces were examined for bacterial colonization, fiber disruption, and disbonding. Mechanical testing and acoustic emission examinations were used to evaluate degradation of tensile strength.
