Abstract: 
To study the influence of water absorption on Flexural properties of Wood-plastic composites (WPCs), The WPCs made of virgin and recycled high density polyethylene (as resin) and 4 types lignocellolusic fillers (wood flour, MDF waste, particleboard waste and rice hull) at 60% by weight fiber loadings, were manufactured using a dry blend/hot press method. The prepared specimens were immersed in water for 1 and 4 weeks. Flexural specimens based on ASTM D7031-04 were tested. The results showed that the flexural modulus and strength were affected by polyethylene (virgin or recycled), type of used fillers and immersion time in water.
