A method of preventing cracking during heat treatment of thick-walled glass-fiber-reinforced plastic shells

  • 22 Accesses


To avoid cracking of thick-walled glass-fiber-reinforced plastic shells during heat treatment, it is suggested that the shells should be heat treated under pressure. This method is based on a comparison between the kinetics of the internal stresses σr.max(T) and strength σ r str (T) during cooling. The authors give expressions for the optimum pressure, based on an elastic model of the material.
