The Influence of External Plasticizers on the Long Term Performance of Carbon Fiber Composite Matrices,

Abstract

Fiber reinforced polymeric composites intended for structural applications are expected to suffer exposure to a variety of plasticizing solvents which can degrade their long term mechanical performance. Procedures are reported for characterizing and predicting the influence of such external plasticizing agents on the viscoelastic behavior of high performance carbon fiber reinforced epoxy composites. Primary attention was directly focused on characterizing the behavior of the polymeric component. Plasticization effects were examined for typical components of a stripping solvent (e.g., phenol, methylene chloride, water) as well as combinations of the components. The qualitative influence of the plasticization agent was determined from weight gain, swelling, and the time required for perceptible color changes to occur. Quantitative effects were determined by comparing the viscoelastic properties of the exposed resin to unexposed control specimens. jg p3
