Study on Tensile Properties of CFRP Plates under Elevated

The reason is that the epoxy resin was used to shape FRP fibers when FRP plates were formed. However, the epoxy resin on the CFRP plates softened in varying degrees when the exposure temperature reached or exceeded the glass transition temperature of the epoxy resin.

The fracture energy of some epoxy resin materials

The double cantilever beam technique has been used to measure the fracture energy of a series of cured epoxy resins. A range of materials was produced by varying the proportion of resin to hardener agent (Araldite CT200 and hardener HT901 phthalic anhydride, CIBA Ltd) and by adding silica flour or aluminium powder as a filler. The fracture energy for crack initiation in the cured epoxy ...
