Abstract

In this study, woven kenaf/glass reinforced composites have been experimentally investigated. Hybrid composites were fabricated by hot press technique. Hybrid composites consists of woven glass fibre and woven kenaf fibre at symmetrically configuration. Non-hybrid glass/polypropylene and kenaf/polypropylene were also fabricated for comparison purpose. Tensile test was conducted using universal testing machine at speed of 2.00 mm/min. While for the quasi-static penetration test was conducted under crosshead speed of 1.27mm/min with 12.7mm diameter indenter. The low-velocity impact test was conducted by using drop-weight machine to study the impact resistance of the specimens. Failure mode of the tests samples were carefully examined. The results from the study showed that the hybrid samples influenced the impact resistance and tensile properties compared to non-hybrid kenaf and glass reinforced composites. It could be seen that the specific energy absorption for glass hybrid with kenaf was the highest among all test specimens. These finding inspired further exploration of hybrid composite for kenaf/glass reinforced composite for other applications.
