AbstractA mixed culture of fungi, enriched from degraded polymeric materials, formed biofilms on coupons of fiber-reinforced polymeric composites (FRPCs). They grew actively in aqueous extracts of the composites under ambient conditions. The data indicate that the fungi utilized the resins or fiber chemical sizing as carbon and energy sources. A progressive decline in impedance from above 10 7 Ohms to below 10 6 Ohms was detected in the inoculated FRPC panels by electrochemical impedance spectroscopy (EIS) after 179 days of incubation, but not on the sterile controls. The degradation proceeds through an initial ingress of water into the resins, followed by degradation of bonding between fiber surfaces and resins and finally separation of fibers from the resins. At the end of EIS study, the extent of disbonding in the inoculated composite was greater than the control observed by scanning electron microscopy. These results suggest that the composite materials are susceptible to microbial attack by providing nutrients for growth.
