Friction property of multi-layer interlocked fabric reinforced COPNA resin composite

Composite materials were made from multi-layer interlocked fabrics which were woven with pitch-based carbon fiber rovings and COPNA resin matrix. Thermal conductivity of the composite materials were measured by guarded heat flow meter method and transient hot wire method. Limiting PV value of the composite materials were measured by using cylinder/plate friction machine. Then, the relation ship between the structure of multi-layer interlocked fabric and those properties of materials was investigated. The result are summarized as follows; The thermal conductivity and limiting PV value of composite materials were higher than those of single COPNA resin material. It was found that self-lubrication of the composite materials was effectively expressed by the fabric structure with carbon fiber ravings highly dispersed.
