Abstract
The work presented in this paper covers an experimental study on finding the effect of fiber volume fraction, width to diameter (W/D) ratio and clamping pressure on single bolted lap joint of woven jute fabric reinforced epoxy and woven glass fiber reinforced epoxy (GFRP) composites. Composite laminates were prepared by hand layup technique and were made with two different fiber volume fractions. GFRP laminates were made with three staking sequence. For each volume fraction, four different W/D ratios were studied. In each group unnotched member was also fabricated and tested to determine the efficiency of the joint. All the tests were conducted on Zwick universal testing machine. The result of the study indicates that the joint efficiency increases continuously with the increase in the fiber volume fraction but decreases with the increase in W/D ratio. Tension and cleavage type of failure modes were observed on the specimens. The effect of clamping pressure and clearance on joint strength of GFRP laminates is also presented.
