Abstract:

The susceptibility of currently used CFRP to impact has stimulated the development of improved Composites. This new generation of composites usually shows increased toughness and damage tolerance as well as improved tensile performance. This is generally not matched, however, by a similar improvement in compressive properties which then becomes a limiting design factor. For improvement of the compressive strength a better understanding of the compressive failure behaviour is needed. This aspect is part of a cooperation programme within GARTEUR. The compressive failure behaviour is being examined at the microscale level single fibre and bundle tests and at coupon level. For experimental verification of failure models special attention has to be paid to compressive test procedures in order to achieve optimal strength values with a minimum of scatter. To evaluate the most appropriate compression test method a Round-Robin test programme was performed on unidirectional laminates of the materials T8006376 HTA7982 HTA76376 T8005245 T800924 IM4005245 and T4006376. In the present paper the results of the Round-Robin test programme are discussed. Carbon fibre reinforced plastics, Compressive strength, Test methods.
