Abstract

Glass fiber reinforced plastic (GFRP) skins bonded onto low density cores, offer potential mechanical properties which can be used various industries such as automobile, aerospace, marine and defence because of their high specific stiffness’s and strengths, excellent thermal insulation. In this research, aluminium foam core with the thickness of (0.5 & 1 mm) sandwiched with glass fibre epoxy laminate are fabricated using hand layup process. Mechanical properties such as tensile, impact and flexural strength was investigated on the fabricated samples. It this work it was observed that, maximum of 115.52 N/mm2 tensile strength was obtained in the aluminium foam core with 1 mm thickness sandwiched with glass fibre composites. Also 84.28 J/m impact strength was obtained. 276 Mpa flexural strength was obtained for 1 mm thickness aluminium foam core sand witched with glass fibre
