Methods of Improving the Matrix Dominated Performance of Composite Structures: A Technical Review.
Abstract
Contained herein is a discussion of methods of increasing the matrix dominated properties of two-phase, continuous fiber/polymer composite materials by the addition of a third phase. For example, a resultant composite exhibiting improved matrix dominated properties may consist of an epoxy matrix binding together both silicon carbide whiskers and continuous graphite fibers. The potential exists to hold the fiber volume content at a level of approximately 50 to 60 percent while displacing 5 to 15 percent of the epoxy with whiskers. The resultant fiber/whisker/epoxy composite has the potential to exhibit superior strength and stiffness to weight properties as compared to a fiber/epoxy composite. The distinct approaches are examined. The first appraoch utilizes the fibers as a carrier for the whiskers, or third phase. It is proposed that silicon carbide whiskers be grown directly on the surface of graphite fibers. These fibers can then be impregnated with the epoxy matrix. The second approach is to utilize the epoxy matrix as a carrier for the whiskers. Silicon carbide whiskers can be added to the epoxy prior to impregnation of the graphite fibers.
