Abstract

Abstract: The aim of present work is to evaluate the surface micro topologies and crystalline behaviour of hybrid wood composites which is prepared by hand lay-up method using pinus and shorea robusta wood particulates as reinforcement materials and epoxy resin as a matrix material. The surface micro topologies and crystalline behaviour of the prepared hybrid wood composites are examined by optical non-destructive test and x-ray diffraction respectively. The surface micro-topological parameters such as average roughness ( R a ), maximum peak-to-valley height ( R t ) and mean peak-to-valley height ( R z ) are recorded by the optical profilometer. The crystallinity of hybrid composite is measured in diffractograms recorded by the x-ray Diffractometer. The surface roughness of shorea robusta wood particulates composite decreases by 31.7% with the addition of equal amount of pinus wood particulates; shows a positive effect of hybridization of these two wood particulates. Moreover, a positive effect of hybridization is also observed in crystalline behaviour as hybrid wood composites exhibited the better crystallinity as compared to single wood composites.
