ABSTRACT:
A novel ignition resistant or fire blocking composite is disclosed comprising a multiplicity of biregional fibers with a thermoplastic or thermoset polymer, wherein each said biregional fiber comprises an inner region of a thermoplastic polymeric core and an outer region of a carbonaceous sheath, and wherein said biregional fibers are present in the composite in an amount of from 10 to 95% by weight, based on the total weight of the composite. In one embodiment, the multiplicity of biregional fibers are treated with up to 20% of a polymerizable silicone resin. In a further embodiment the thermoplastic or thermoset polymer is in the form of a sheet or panel and said multiplicity of biregional fibers are distributed throughout the polymeric matrix of the sheet or panel in an amount of from about 20 to 75%.
