PROCESSING TECHNIQUES FOR MANUFACTURING HIGH VOLUME FRACTION CEMENT BASED COMPOSITES

This study evaluates several hybrid reinforcing systems and their manufacturing techniques for primary use in the area of thin fiber composites. Emphasis is placed on the development of high volume fraction FRC materials using a variety of fiber types and matrix formulations. The fiber types include glass, polypropylene, ceramic, and carbon both in a mesh and discrete form. Several changes are made in the matrix formulations in order in order to accelerate the setting of the cement. Combinations of brittle whiskers, ductile fibers, and continuous fiber mesh reinforcements enable production of an array of new materials with improved strength and toughness. Procedures for manufacturing these composites are also presented. A high energy mixing method is developed to incorporate up to 16% by volume of short fibers. Casting techniques, such as single screw extrusion, that may be employed in forming various sections and geometries are discussed.
