On the analysis of compressive failure load of single-lap bolted joint of green composites

Abstract

Abstract In the present study, bamboo fiber reinforced polylactic acid (PLA) composites have been fabricated by hot compression molding using film stacking method. The compressive failure load behavior of single lap bolted joint of the developed composites has been experimentally investigated. The influence of the geometric parameters of mechanical bolted joint such as width to diameter ratio (w/d), edge to diameter ratio (e/d) and bolt fastening torque on the compressive failure load has been statistically analyzed. Taguchi’s analysis has been performed to find the optimum level of geometric parameters to obtain higher compressive failure load of the bolted joint. The w/d and bolt fastening torque were found to be significant parameters influencing the compressive failure load of the bolted joint. The compressive failure load of the bolted joint is more at a higher value of w/d and bolt fastening torque.
