Abstract

Described herein are compositions which contain a specific group of oligomeric diamine hardeners and epoxy compounds which when combined with structural fibers produce composites which have improved tensile properties, high compressive strengths, and improved impact resistance. These compositions also exhibit low moisture absorption.
