Large castings of hot-setting plasticised epoxy polymers developed surface crazing after being subjected for several hours to moderately high temperatures. The phenomenon was attributed to rejection of the plasticising agent by the surface layer of the material and the resulting local change of mechanical properties. Thermal crazing appears to be extremely sensitive towards stress concentrations and cracks usually follow principal stress patterns. Visualisation of frozen or residual stress fields is, therefore, possible. The material in thin sheet form can also be applied as brittle coating, being bonded on stressed metal surfaces and producing by cracking, principal stress patterns corresponding to acting loads combined with thermal stresses. © 1974.
