This paper is concerned with the time and temperature dependences of the static flexural behavior in CFRP laminates consisting of high temperature epoxy matrix and satin woven carbon fibers. Dynamic viscoelastic tests for neat resin and three-point bending tests for CFRP laminates were carried out under various loading rates and temperatures. The results obtained are summarized as follows;(1) The mechanical behavior of epoxy resin used was remarkably dependent upon time and temperature even in the vicinity of room temperature that is sufficiently lower than the glass transition temperature Tg.(2) The static flexural strength of CFRP laminates was also remarkably dependent upon time and temperature over a wide range of temperature even below Tg.(3) The time and temperature dependences of the static flexural strength of CFRP laminates was dominated by the mechanical behavior of matrix resin.
