<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. 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. Preferably the polyacohol is selected from one or more of glycerol, sorbitol, xylitol, mannitol, 1,2-propane diol, 1,3-propane diol, and 1,2-ethane diol, in particular glycerol. The polyacid preferably is an aliphatic diacid or triacid with 3-15 carbon atoms. Examples of suitable acids include citric acid, succinic acid, and itaconic acid.</p> |
