Evidently, there is the lack of test data for composite materials, particularly for fiber reinforced plastics most likely to be used in the coupling areas. The knowledge of load-carrying capability for different joint geometries and associated fracture modes are needed for bolted-joint design. An experimental program to determine the bolted-joint strength and fracture modes for Mat-FRP at 120°C, 80°C and room temperature has been conducted in order to obtain such preliminary design data.
In this paper, the effects of joint geometry and temperature on joint strength and fracture mode are presented.
It is concluded that both fracture load and mode can be predicted from joint geometry and temperature. By taking fracture mode into consideration, the following experimental equation is proposed to estimate the fracture load.
Pmax=k·P0
k=exp[α(w-d/d)+β(w-d/d)+γ(T-20)2]
