Interfaces of Organic Matrices and Graphite Fiber Composites: A Review of the Literature
Abstract
One of the most interesting and unique problems with advanced organic matrix composites is the fiber/matrix interface (or interphase), which is crucial in determining the material's overall properties. In the past, adhesion between the fiber and matrix has been induced by trial and error. With the current explosion of material systems and the advent of inert thermoplastic matrix materials, much more energy from industry and academia has gone into investigating and defining the interface, yet real scientific understanding eludes them. This report reviews the current literature concerning the interface between the organic matrix materials and graphite fibers. Concepts introduced include wetting, adhesion, fiber surface modification, methods of investigation of fibers and matrices, surface chemistry, and morphology of graphite fibers and organic matrix materials. In addition, the interfacial effort on mechanical properties and interfacial shear strength testing are reviewed. It is determined that a complete scientific understanding of the chemistry, morphology, electrostatic nature, and molecular conformation of the carbon fiber surface and matrix materials is essential to alleviate poor adhesion in organic matrix composites.
