Abstract: Boron fiber was originally developed in the 1960s as a high strength, high modulus reinforcement for composite aerospace structures. It is produced by a chemical vapor deposition process as a relatively large diameter (100-140 µm) monofilament. New enhancements to boron composite prepreg manufacturing methods have enabled compatibility with automated fiber placement machines, thus allowing increased flexibility in the tailoring of composite mechanical and thermal properties. Boron fiber remains relevant for current and new aerospace structures due primarily to its very high compressive strength relative to carbon fibers. Recent development results will be presented showing the properties of boron fiber-reinforced composites in several resin systems. Results with hybrid boron-carbon composites in particular showed an 80-170% increase in compressive strength relative to the carbon-only analog composites.
