摘要

The use of Continuous Filament with Special Characteristics in the forming processes of the Composites, including Filament-Winding, Poltrusion is increasing rapidly. In this study, fiberglass and saturated polyester yarn (with different structures) are applied as the central core and the cover, respectively. The former due to its high module & Tensile strength and the latter due to its high extensibility. They are used in a matrix of unsaturated polyester resin in the form of three layered, unidirectional fabric. The present article studies the influence of covering percentage and polyester cover structure on physical & Mechanical properties of the compounds. Physical & Mechanical tests have been carried out in both vertical & horizontal direction to the fiber orientation. Results showed that the tensile & impact energy absorption and so the other mechanical characteristics of the compound reinforced with glass yarn which is in turn covered with spun polyester show a much more better performance than the others. Furthermore, a twist of 400 TPM covering yarn can improve the mechanical properties of the compounds significantly. Twist, structure and the kind of covering yarn could have an influence on the surface fracture of the composites. Thereby, it would become possible to alter the surface fracture form a destructive state to a controlled one.
