Abstract

A class of new structural materials with a significant degree of ductility and strength are introduced that are durable, strong, and cost effective. High fiber content cementitious materials (FRC)are manufacturd using a computer controlled closed loop system for pultrusion and filament winding. Composites consisting of unidirectional lamina are manufactured. Mechanical response of laminates is measured using closed loop uniaxial tensile and flexural tests. Various mechanisms of delamination, debonding, and crack deflection are identified, resulting in an ultimate strain capacity of 2%, and a fracture toughness as much as two orders of magnitude higher than the conventional FRC materials. The extent of matrix cracking, ply delamination and crack deflection mechanisms are studied by means of fluorescent microscopy.
