The purpose of this paper is to study the effects of water immersion-freeze-thaw treatment on the physical properties, flexural strength (FS) and morphology of wood-polypropylene composites. The behaviour of wood plastic composite is difficult to predict due to the complexity in the structure of the material. Wood consists of cells (fibres) arranged in an intricate pattern, and the behaviour of the material is a result of the behaviour of the cells and the cell arrangement. In this thesis, different approach will be employed to analyze various degradation in wood plastic composite. This study will revealed whether the flexural strength and dimensional stability of the wpc will decrease or increase after exposure to water immersion-freeze-thaw cycling and water absorption fatigue, also the degree of changes in the surface properties (colour and roughness) of the composites after exposure to water immersion-freeze-thaw cycling. This study is a part of an ongoing study on weathering of wood-polymer composites (WPC), the results of this study will be obtained from accelerated laboratory experiments.
