Hy-Bor® Prepreg Tape

Combining Specialty Materials' boron fiber with carbon prepreg, Hy-Bor® is a high-performance material with exceptional properties that offers a great carbon fiber alternative. Our standard Hy-Bor® product utilizes Mitsubishi Rayon’s MR-40 carbon fiber and NCT-301 250°F-cure epoxy resin with our 4-mil diameter boron fiber. Hy-Bor® can be manufactured to incorporate any commercially available carbon prepreg and polymer resin system. By altering the spacing of the boron fiber in the prepreg, performance properties and material costs can be tailored to meet the needs of a variety of demanding applications.

Unidirectional Dry Woven Boron

The primary product for boron fiber sales is a unidirectional tape pre-impregnated with epoxy resin. For customers who require a dry woven preform for wet lay-ups, such as resin transfer molding or vacuum assisted resin transfer molding, we offer the option of a dry woven product.
