Abstract
Polyethylene fibers reinforced Resol/VAC-EHA composites have been prepared in the laboratory at different volume fraction of fibers for the evaluation of mechanical properties. Resol solution was blended with vinyl acetate-2-ethylhexyl acrylate (VAc-EHA) resin in an aqueous medium with varying volume fraction of polyethylene fibers. It has also been observed that reinforcement of the polyethylene fiber in Resol/VAC-EHA matrix shows improvement in ductility, tensile strength and Young's modulus. But damping property decreases as soon as percentage of the polyethylene fiber increases. In order to study the static and dynamic response of polyethylene fiber reinforced Resol/VAC-EHA composite plate at uniformly distributed load and fluctuating uniformly distributed load, a multi-quadric radial basis function (MQRBF) method is developed. MQRBF is applied for spatial discretization and a Newmark implicit scheme is used for temporal discretization. The discretization of the differential equations generates a greater number of algebraic equations than the unknown coefficients. To overcome this ill-conditioning, the multiple linear regression analysis, based on the least square error norm, is employed to obtain the coefficients. Simple supported and clamped boundary conditions are considered. Numerical results are compared with those obtained by other analytical methods.
