<p>A composite material comprising 20-98 wt. % of a synthetic particulate or fibrous filler and at least 2 wt. % of a polyester derived from an aliphatic polyalcohol with 2-15 carbon atoms and a polyacid, wherein the alcohol comprises at least 50 mole % of glycerol, and the acid comprises at least 50 wt. % of tricarboxylic acid. Preferably, the filler is in the form of particles, fibers, and/or random or non-random layers. Preferably, the filler is based on one or more of ceramic, including glass, in particular glass fibers, polymer, in particular polymer fibers, and carbon, in particular carbon fibers. The use of glass fiber based sheet-like material as filler is a particular embodiment of the invention. The composite material according to the invention has fire-retardant properties, which makes it particularly suitable for applications where fire-retardancy is an issue.</p> |
