Abstract
The addition of a low softening point glass of Tg 300.degree.C and optionally a blowing agent, to a reinforced thermosetting composite material gives fire retardant properties to the product. Smoke emission on burning is less than for halogenated fire retardant additives. A preferred embodiment is GRP sheet containing a powdered phosphate glass and a blowing agent.
