Third Phase Fiber Addition to Advanced Graphite Composites for Improvement of Impact Strength.

Abstract

Notched and unnotched instrumented Charpy impact data and tensile, flexural, compressive and shear property data of multi-angle and hybrid graphite reinforced epoxy resin composites are presented from the perspective of property trade-off studies. Two Modulite 5206 basic graphite fiber orientations are evaluated; composites in which the filament repeating unit direction is 1) 0 degrees, and 2) 0 degrees, + 45 degrees, -45 degrees and 90 degrees. The hybrid configurations are fabricated using the basic graphite orientations with discrete amounts of supplementary third phase fibers (glass, Nomex, and PRD-49 Type III) interspersed in the composites in 0 degree and in -45 degree and + 45 degree directions.
