QUALITATIVE CORRELATION BETWEEN FRICTION COEFFICIENT AND METAL SURFACE WEAR IN THE CASE OF LINEAR FRICTION DRY CONTACT WITH REINFORCED POLYMERS WITH GLASS FIBRE
Composite thermoplastic materials are biphasic materials consisting of a mass of polymer and the reinforcement embedded in it. The polymer provides the compressive strength of the material, while the reinforcement improves the tensile strength. Homogeneity of the material and its cohesion has an important role in obtaining some good mechanical characteristics. Thus, the disposal of the reinforcement considerable influences the tensile strength feature. Also the elasticity of the polymer can improve the compression resistance or bending resistance of the reinforcement material. The role of the basic polymer is first of all mechanical and is to provide the bond with the reinforcement fibres. It is the one that transmits the efforts between the reinforcement fibres.
