Abstract: Composites materials are widely used in all industries all over the world, replacing many other engineering materials. Reasons for such popularity are many, among such, are their physical and mechanical properties in addition to the simplicity of their manufacturing processes. Machine elements that are made of polymeric materials are usually exposed to different causes of failure such as wear. The time effect on the wear behaviour of some composite materials (polyester�commercially fiber reinforcement named (E-glass) was studied. In this study four type of composite different in number of layers, it had (3-6-9-12) layers (Wear volume 0.48, 0.41, 0.71 and 0.78, respectively). All experiments were conducted under dry condition. Preliminary results show the wear volume increases for all examined composites, as the statically applied load increases. Fourth type has the highest wear resistance, then third type and lastly first type. The wear volume increases for all examined composites, varied of time increases.
