**Abstract**
 A method to repair a broken moulded thermoset piece is described. It involves the use of an unsaturated polyester in a two stage procedure. The first involves putting pure resin on the surface of the broken piece over a period of time and then putting this pre-treated piece in the mould in which it was originally, with fresh uncured thermoset made of pure resin with fibreglass and filler, to fill the mould and then curing it. The pretreatment resin on the surface of the broken piece is in contact with the fresh uncured thermoset. The mechanical properties in elongation and flexion of the final material are measured, and it appears that not only is the diffusion of pure resin into the part responsible for an increase in mechanical properties, but also that the time of diffusion is influential. 12 refs.
