EFFECT OF OVERLAP LENGTH AND ADHESIVE THICKNESS ON THE SHEAR STRENGTH OF JUTE FIBRE COMPOSITE AND FIBREGLASS COMPOSITE JOINTS

Abstrak

Adhesively bonded joints have attracted the attention of engineers for connecting different materials to develop lightweight structures. The materials that can be bonded include composite materials with different reinforcements, such as glass and natural fibres. This study aims to determine the effect of overlap length and adhesive thickness on the shear strength of jute fibre-reinforced composite and glass fibre-reinforced composite joints. This study used single lap joints according to ASTM D1002. The overlap lengths varied by 15, 20, 25, and 30 mm, while the adhesive thicknesses varied by 0.2, 0.4, and 0.6 mm. From the results of this study, it was found that joint strength tends to decrease with increasing overlap length, whereas the effect of adhesive thickness depends on overlap length. At overlap lengths of 15 and 20 mm, joint strength increases with increasing adhesive thickness; at 25 and 30 mm, it appears to remain constant.
