Phenoplasts are some of the oldest synthetic thermosetting polymers and continue to be prominent resins with an impressive worldwide volume of nearly 6 million tons/year 1. Phenolic resins for composites contain water initially and, even after curing, a composite is likely to contain 0-4 %wt water at equilibrium. Asim et al. Dow Corning Corporation, PO Box 994, Midland, MI 48686‐0994, USASearch for more papers by this author. Like epoxy resins they are addition-curing and exhibit comparable or superior thermal and mechanical properties, whereas for flammability properties they are far superior to epoxies and in the same range as phenolic resins. In order to further improve non-flammability, the phenolic resin foam material was also added with inorganic materials, such as, calcium silicate or calcium carbonate as a filling agent.
