Abstract

Objects are made by laying on each of two halves of a two-component matrix a layer of hardening synthetic resin-impregnated glass fibres, supported by a flat film, in both halves drawing the film/impregnated glass fibre assembly tightly against the walls by means of a vacuum, subsequently joining the halves whilst maintaining the vacuum and the synthetic resin has not yet set, and hardening the resin layers whilst maintaining the vacuum. Specifically, the synthetic resin is a cold or thixotropic heat setting polyester or epoxy resin and the film is a polyethylene terephthalate, PTFE, Cellophane (r.t.m.) or polyvinyl alcohol film.
