Abstract

Fabric reinforced cement based composites are a new class of composites with superior tensile strength and ductility which have the potential for becoming load bearing structural members. This enhanced behavior is primarily governed by interfacial bond characteristics between fabrics and matrix. Pullout tests were conducted using several different matrices and fabric types: two different mix designs (control and with fly ash); and four fabric types: alkali-resistant glass, polypropylene, polyethylene, and polyvinyl alcohol. The effects of processing methods: cast, pultrusion, and vacuum as well as fabric embedded lengths (7.6 and 12.7mm) were also evaluated. The Naamam 1991 pullout model was modified in this paper and used to investigate the bond mechanism expressed as shear strength diagram. The shear strength parameters obtained by fitting the pullout simulation curves to the experimental responses are agreed well with the nominal shear strength obtained directly from the experiments. It was found that the pullout responses are highly dependent on the fabric type, mixture design, and processing method.
