The influence of superimposed normal stresses on the ILSS of laminanted C/C composites at temperatures up to 2000 deg C
Abstract
The interlaminar shear strength (ILSS) of composites is strongly influenced by superimposed normal stresses. In order to determine this effect quantitatively, a test procedure was developed which allows measurements of the ILSS in dependence on compressive stresses perpendicular to the laminae at temperatures up to 2000 deg C. This procedure was applied to C/C as an example. It is found that the ILSS increases with increasing superimposed compressive stresses. Additionally, with rising temperature the shear resistance increases, too.
