Evaluation of the Influence of Glass Fibre Distribution in Polyamide Matrix During the Consolidation Process on the Mechanical Properties of GF/PA6 Composites

摘要

This paper presents the relationship between the glass fibre arrangement in a polyamide 6 matrix during the consolidation process and the mechanical properties of CF/PA 6 composites. Three specially designed hybrid yarns were used to produce the composites. The different structure of yarns and the different level of blending of the reinforcing and thermoplastic fibres in yarns give different conditions of fibre impregnation and of the matrix crystallisation process. The thermal conductivity and micro-thermomechanical behaviour of the polyamide matrix at selected places of the composite surface were studied by means of micro-thermal analysis. Differences in the supermolecular structure of the matrix described by μTMA influence the mechanical properties of the composites.
