Most commercial glass and carbon fibers used in polymeric composites are coated with sizings, which may serve several purposes, including facilitation in handling, protection of the fibers, aid in processing, and enhancement of composite behavioral characteristics through modification of adhesion characteristics. Under appropriate conditions, sizings have been shown to cause the formation of interphase regions that possess gradients in material properties and affect composite behavior. Sizings affect two aspects of composite performance: composite behavioral characteristics and processing performance. In both cases, microscopic phenomena are responsible for observed macroscopic effects. On a microscopic level, the behavior of a formed part is affected by the formation of interphase zones that can lead to variations in local properties such as modulus and glass transition temperature. Such microscopic effects may in turn influence processing by affecting apparent cure kinetics and macroscopic flow behavior. The degree to which sizing selection may affect the RTM process is investigated and special attention paid to the key facets of processing.
