Interphase structure-property relationships in polymer matrix composites
- Owens-Corning Science and Technology Center, Granville, OH (United States)
Polymer matrix composites (PMCs) usually are produced by combining multicomponent polymers with fibers that have surface treatments and {open_quotes}sizing{close_quotes} layers applied by high-speed industrial processes. This review presents recent developments in our understanding of the composition and properties of the interphase that is formed at the boundary between the fiber and matrix, and its role in composite performance. Focussing on glass- and carbon-fiber PMCs, we show relationships among surface chemistry, thermodynamics, microstructures and measurements of the interfacial shear properties of single fibers in a matrix. Theoretical micromechanics and statistics models of composites with interfaces are described, complimenting the experimental studies, as well as providing a capability to compute properties, including size factors and lifetimes. Also discussed are tests employing several industrial loading laws on a variety of {open_quotes}real{close_quotes} composite structures with {open_quotes}tailored{close_quotes} interphases.
