Abstract

The eco-friendly composites containing PA11 and CP were investigated in order to apply to the functional parts (e.g. sliding parts) in this study. Mechanical properties and tribology properties of PA11 composite were compared with PLA composite or POM. The specimens were prepared by the mixing process using a co-rotating twin-screw extruder and the moulding process using an injection-moulding machine. As a result, both properties of PA11/CP30wt% were reached the each target values. It was related to the Vickers hardness of the PA11/CP composite that the wear loss of the composite when the friction-and-wear test had carried out under a general test condition. It was improved due to suppressing the sliding heat generation that the friction-and-wear property of PA11 composite including high-CP content, because the heat conductivity of composite was low value.
