An article of manufacture in the form of a shaped sheet, comprising 50-90% by weight of PET, 5-20% by weight of a "rubber", 10-45% by weight of an inert filler, and having a crystallinity gradient such that said shaped sheet maintains the shape, under its own weight, up to a temperature of at least 70 DEG C and has impact strength which is substantially greater compared to that of the fully crystallized shaped sheet.
