Significant Properties of Epoxy Resins as Matrices in Graphite Composites.

摘要

It is desirable, for purposes of developing better resins, to know what properties of thermosetting resins are most significant in affecting the structural properties of grahphite fiber/resin matrix composites. Unidirectional and multidirectional composites were fabricated and evaluated using five resin matrix systems. The influence of these resin properties on composite performance was examined through the experimental evaluation of composites fabricated from several resin materials possessing rather widely varying mechanical properties. Composite properties measured include: initial modulus, proportional limit, and ultimate strength.
