Investigation of the impact properties of glass fibre / HMPP fibre hybrid composite materials for civil infrastructure constructions

Abstract

Advanced fibre composites which were primarily developed for defense and aerospace industries have made inroads into fast growing and high volume civil infrastructure industry nearly a decade ago. There are traditional para-aramid synthetic fibres such as Kevlar which are significantly expensive for the use of civil infrastructure construction. The recent development of less expensive, high modulus synthetic fibre has opened a new path for the development of cheaper, high performance, impact resistant composites which are affordable for civil infrastructure development. This paper details a study of lower cost, high-energy absorbent continuous fiber laminates, and in particular, high modulus polypropylene (HMPP)fibers. Innegra™ S is the commercial name used by Innegrity for its HMPP fiber.
