Fibre Matrix

The predominant damage process occurring, when unidirectional composites are subjected to transverse tension, is interfacial failure events which are detected as acoustic emission(AE) by a transducer in contact with the test piece. The stress and strain range over which these AE events occur determine the strength of the fibre—matrix interface, while the relative number of recorded events give indication as to the interfacial failure mode.

Fibre Reinforced Composites

The fracture behaviour of long fibre reinforced composites is predetermined mainly by properties of fibre-matrix interface. The matrix prepared by pyrolysis of polysiloxane resin possesses ability to resist high temperatures without significant damage under oxidising atmosphere. The application is therefore limited by fibres and possible changes in the fibre matrix interface. The study of development of interface during high temperature exposition is the main aim of this contribution. Application of various techniques as FIB, GIS, TEM, XRD allowed to monitor microstructural changes in the interface of selected places without additional damage caused by preparation. Additionally, it was possible to obtain information about damage, the crack formation, caused by the heat treatment from the fracture mechanics point of view.
