Experimental Strength of Single-Lap Hybrid Joints on Woven Fabric Kenaf Fiber Composites Under Quasi Static Condition

Abstract

Abstract. For the past decades, usage of natural fiber reinforced composites in low bearing load applications are increasing tremendously due to drawbacks concerning the use of synthetic fibers. Kenaf fibers have a good potential to be used as composite reinforcements as they possesses excellent fiber strength compared to own self-weight. Current work concentrates on mechanical properties of woven fabric kenaf composites with single-lap hybrid joints configurations. Four width to diameter ratio, (W/d) of cross-ply lay-up joints as designed in testing series were tested by using quasi static mechanical testing. Experimental results showed that the failure load increased with the increasing of W/d ratios. Thinner lay-up had better bearing strength compared to thicker lay-up as found in current study.

Notched Strength of Woven Fabric Kenaf Composite Plates with Different Stacking Sequences and Hole Sizes

“…Excellent tensile strength and modulus of kenaf fibres were reported by previous researchers [1]. Previous works [2] reported promising results of un-notched strength of woven fabric kenaf composite plates. Research works on other natural fibres are aggressively ongoing in searching for utilizing natural fibre in composite materials that are renewable and sustainable.…”

A comprehensive review on the machining and joining characteristics of natural fiber‐reinforced polymeric composites

“…Higher joint strength was observed at crossply layup composites. 128 Kmaludeen et al studied glass/epoxy and basalt/epoxy lap joints using adhesive through FEA. They studied a hybrid joint also using rivet joining and adhesive joining.…”
