Specialty Materials

What Specialty Materials does

Specialty Materials, Inc. (legal entity Global Materials, Inc.) manufactures advanced composite fibers and prepreg tapes at a single ISO 9001:2008 certified facility in Lowell, Massachusetts. The company operates several hundred continuous chemical vapor deposition (CVD) reactors to produce boron fiber (4.0-mil, 5.6-mil, and 3-mil diameters) and silicon carbide fibers (SCS-6, SCS-Ultra), making it the world's sole manufacturer of boron fiber with 50+ years of continuous production know-how rooted in the original Avco commercialization of 1974 and continued through Textron ownership before spin-off in 2001 and acquisition by Global Materials in 2019.

The product portfolio centers on three fiber platforms. The flagship is Hy-Bor, a tunable commingled boron-carbon fiber unidirectional prepreg offering 2-3x improvements in compression strength, compression after impact, open-hole compression, and bearing strength versus pure carbon fiber composites, with a Gen 2 lineup developed jointly with Toray Advanced Composites using Toray T1100G carbon and five new resin systems. SCS silicon carbide fibers serve titanium matrix and ceramic matrix composite applications in high-temperature aerospace, with SCS-Ultra being 50% stronger than SCS-6. HY-SHIELD, currently at TRL 2-3, applies the CVD platform to hybrid boron-tungsten structural shielding for fusion reactors. Supporting offerings include boron epoxy and cyanate ester prepreg tapes, boron nanopowder, and 1.3-mil carbon monofilament for electrochemical microelectrodes.

The business model is direct enterprise field sales of premium-priced, quote-based specialty fiber and prepreg materials to aerospace primes (Boeing, Sikorsky, Northrop Grumman), defense contractors (General Atomics for Predator B/MQ-9 spar caps), space programs (NASA JWST kinematic mounts, Maxar WorldView satellite secondary mirror tubes), and sporting goods OEMs (Bauer Hockey, HEAD Tennis, Winston Rods, Calfee Design, historically Callaway Golf), supplemented by an online storefront with public 2026 price lists for standard products, engineering services (composite design assistance, mechanical and analytical testing), and in-house autoclave/oven processing. Revenue is generated through volume-tiered per-linear-foot or per-pound pricing on long-lived, specification-driven programs where Specialty Materials is sole-qualified; revenue magnitude is undisclosed. Marketing is conducted via CAMX, JEC WORLD, and SAMPE trade shows, technical datasheets, and academic collaborations including Imperial College London and NIAR.

Core offering

Specialty Materials manufactures boron fiber and silicon carbide (SiC) fiber products via chemical vapor deposition (CVD) at its Lowell, Massachusetts facility. The company sells raw monofilament fibers (boron, SCS-6 and SCS-Ultra SiC, carbon monofilament) as well as pre-impregnated unidirectional prepreg tapes, including the proprietary Hy-Bor hybrid boron-carbon prepreg portfolio. It is the world's only commercial producer of boron fiber.

Product overview

Specialty Materials is a manufacturer of advanced composite fibers and prepregs, serving as the world's leading supplier of boron fiber and silicon carbide fibers. The product portfolio centers on three core fiber technologies: boron fiber (CVD-produced in 3-5.6 mil diameters), silicon carbide fibers (SCS-6 and SCS-Ultra), and carbon monofilament. These fibers are sold both as raw materials and as pre-impregnated (prepreg) tapes with various resin systems. The flagship Hy-Bor® hybrid prepreg line combines boron and carbon fibers to achieve 2-3x compression strength improvements. Additional offerings include boron nanopowder for superconducting wire, HY-SHIELD® for fusion radiation shielding, and technical services including composite design assistance, analytical testing, and autoclave processing. The company operates ISO 9001 certified manufacturing facilities in Lowell, MA.
