Effect of water on the properties of some polymeric composites


The effect of water was studied on some physical and mechanical propertiesincluding (Roughness, Hardness, Compression Strength), and diffusion coefficientwas calculated using Ficks’ 2nd law for a polymeric composite materialsPVC+carbon black, Epoxy+Al powder, Epoxy + E-glass (chapped)), withvolume fraction Vf=30% reinforcement for all specimens, results showed thenegative effect of water on these properties which is differed between onespecimen and other, PVC+CB was affected more than Epoxy+E-glass thenEpoxy+Al powder and the diffusion coefficient (D) was less for Epoxy+Al thenPVC+CB and the less value was for Epoxy + E-glass .
