This paper is concerned with the temperature dependence of flexural static strength of pitch/PAN hybrid unidirectional CFRP laminates. These laminates were constructed by laminating the PAN based CFRP layers on the compression side of the pitch based CFRP layers. Three point bending tests were performed at a wide range of temperature below and above the glass transition temperature of the matrix resin.
It was found that the existence of a few PAN based CFRP layers in the compression side of the specimen remarkably increased the flexural strength of hybrid CFRP laminates at temperature below the glass transition temperature without decreasing the flexural modulus.
