概要

論文の詳細を見る
In the previous paper, the temperature dependence a strength in the flatwise direction of roving glass cloth FRP was reported for the case where the weakest interface is the fiber/matrix interface irrespective of the fiber/matrix ratio and the condition of heat treatment. The present paper reports the case of roving glass cloth FRP having the fiber/matrix ratio of 100/0 and 0/100, when the weakest interface is not affected by the condition of heat treatment. The results obtained are as follows. (1) The temperature dependence of the brittle or ductile behavior of the interface is affected by the thermal properties of the matrix which depend on the condition of heat treatment, but not by the location of the weakest interface. (2) The temperature dependence of the location of the weakest interface is affected by the fiber/matrix ratio, but not by the condition of heat treatment. (3) The temperature dependence of the bond strength is not affected by the fiber/matrix ratio nor by the condition of heat treatment, but it changes in the specified temperature range.
