Study the effect of fiber orientation on mechanical properties of bidirectional basalt fiber reinforced epoxy composites

The mechanical behaviors and tensile fracture surface morphology of basalt bidirectional mat fiber based epoxy composites were investigated in the present experimental work. Composites with varying fiber orientation angles such as 45 degrees, 60 degrees and 90 degrees laminated using hand layup techniques. Mechanical behaviors like as tensile strength and tensile modulus, flexural strength and flexural modulus, impact strength (charpy & izod) as well as micro hardness behaviors investigated experimentally. The result showed that maximum mechanical properties obtained in 90 degrees fiber orientation composite as compared to other developed composites. (C) 2020 Elsevier Ltd. All rights reserved.
