摘要

For the determination of the Interlaminar Tensile Strength (ILTS) which is the lowest strength that laminated structures exhibit, a testing procedure was developed which avoids the problems of load transfer of the devices normally used today. It is based on the diametral compression test and it can be demonstrated that this test really leads to interlaminar tensile failure inside the material so that reliable strength values are obtained. This procedure was successfully applied to specimens of a carbon fibre reinforced carbon (CFRC) at temperatures up to 1800℃. It is shown that its ILST increases by about a factor of 2 between room temperature and the highest temperature applied.
