Abstract
The present paper reports the uniaxial tensile property of fibre and laminated composite of Dyneema® HB80 prepreg under quasi-static conditions. A detailed experimental work on tensile testing of fibre/filament and its laminated composite has been presented. It has also been discussed about the easy slipping out problem of Dyneema® grade test specimen during experimental work. The tensile strength of the filament of Dyneema® HB80 has been evaluated and found to be 2.96 GPa with an average elongation of 4.15%, closely agreed with the test data of manufacturer, although tensile strength of laminated composite has been found quite low as compared to fibre tensile strength. The effect of curing temperature on the tensile strength has also been studied and found higher strength for the laminate cured at a comparatively lower temperature. The SEM analysis of the fractured samples showed weak macro fibrils resulted in higher degree of damage to the fibre laminate, and hence, lower tensile strength.
