RESEARCH ON HOLLOW AND SOLID GLASS FIBERS AND THEIR COMPOSITE MATERIALS

Abstract

Abstract: To study the properties of hollow glass fiber and its composite, in this work, filament and multifilament tensile strength of hollow glass fibers and solid glass fibers were compared and a glass fiber filament strength model was established. Furthermore, hollow/solid glass fiber reinforced polymers (HGFRP/SGFRP) were fabricated by winding process and molding process, and tensile property and bending property of these two composites were tested. The result indicates that the filament tensile strength of hollow/solid glass fiber coincides well with the Weibull distribution model. Tensile strength and bending strength of hollow glass fibers are lower than that of solid glass fibers. It also shows that the specific tensile/bending strength of HGFRP is less than that of SGFRP. However, the specific tensile modulus and the specific bending modulus of HGFRP are higher than that of SGFRP. Consequently, it can be deduced that hollow glass fibers can be served as a promising reinforcement for the next-generation light-weight composites.

Key words: hollow glass fibers, solid glass fibers, Weibull distribution, composite materials, mechanical property
