    abstract

    Acoustic emission has been monitored as an indication of internal damage during constant load tests of carbon fibre reinforced plastics tensile specimens.lt has shown that no complete stabilisation of the material occurs even after several hours at the same load level and that this accumulative damage can be well represented by a logarithmic function of time. We attempt to provide a physical model with which the time dependent behaviour of the material could be explained. It is hoped that this study will result in a proof-testing method which will allow unforseen failures to be avoided.
