Abstract

Composite materials have been the subject of study mainly synthetic fibers because of their high strength and light weight but non-bio-degradable nature. The waste of the machine pultrusion process in the composite industry has produced waste material in the form of roving, and usually this waste will be discarded, since there are no further studies that applied this waste to convert into application of glass fibre woven mats. Therefore, this study will explore the glass roving waste generated by pultrusion machine to the application of mat weaving patterns. This idea is for fibre waste that can used to make the something to be the product. In this research, the Recycle Roving Fibre Kit (RRF kit) is self-designed hand loom was produced to facilitate users to convert roving waste into glass mat plain weave patterns (RWR). Recycled mat samples (RWR) and commercial mat samples WR 600/(CWR) reinforced Epoxy and hardener using a hand -layup technique to produce test specimens for flexural, impact, density and water absorption testing based on ASTM standards. This study found that the 3 -plies RWR samples produced a maximum increase of 428.11% compared to the 3 -plies CWR in impact properties. Additionally, 1 ply RWR has a 74 % higher impact strength than 2 plies CWR, and 2 plies RWR has a 92% higher impact strength than 3 plies CWR. Despite the RWR samples' excellent impact performance, its flexural properties were inferior to CWR. The density properties of the 3 - plies RWR were almost the same as the 3 -plies RWR sample with a slight difference of 0.5%. The best result for water absorption is 2 plies among the RWR samples, but its performance had an insignificant difference when compared to the 3 plies of CWR which were not more than 30%. It can be concluded, RWR can still be function similar to CWR while having better energy absorption result.
