    • Abstract


      In recent years, there has been a wide interest in fillers which improve the quality and performance of fibre composites when mixed in a small quantity in the matrix. In the present work the effect of addition of mica and graphite powders in cross ply glass fibre reinforced plastic (GRP) composites has been studied by using acousto ultrasonic (AU) technique. The mechanical strengths of these composites were correlated with fibre volume fraction (Vf). The stress wave factor (SWF) was evaluated and correlated with tensile/flexural strengths of these composite specimens. The observations show a linear relationship between the SWF values and strength of unfilled and filled GRP composites.
