Description
Summary:The effect of stacking sequence on the physical and chemical properties of a hybrid composite composed of biomass sheep wool fiber and glass fiber reinforced with epoxy was investigated in this study. The hybrid composite was developed as an alternative material for engineering applications to harmful man-made glass fiber composites. The hybrid composite laminates were made by hand and had a total fiber volume fraction of 60% (biomass sheep wool fiber 30% and glass fiber 30%) and 40% reinforcement. Three distinct stacking sequences, STQ1, STQ2, and STQ3, were prepared and tested in accordance with ASTM standards. The results of the tensile and bending tests revealed that STQ1 biocomposites have higher strength and maximum bending than STQ2 and STQ3 composites. Furthermore, STQ1 biocomposite absorbed more moisture and chemicals than STQ2 and STQ3 composite. Morphological studies of fracture surfaces on biocomposites revealed that STQ1 has better interfacial bonding of fiber and matrix than other composites, confirming its suitability for lightweight applications.
