What ACP Composites does
ACP Composites, Inc. is a custom composite manufacturer founded in 1985, originally in Connecticut and now headquartered in a 33,000 sq ft facility in Livermore, California. The company operates as a family-owned, privately held business with 51-100 employees, holding AS9100:D, ISO 9001:2015, and ITAR registrations. It produces carbon fiber, fiberglass, and specialty composite parts and structures for customers in aerospace, defense, space, medical, sports and recreation, marine, and industrial markets.
ACP operates a dual business model. The primary stream is build-to-print custom composite manufacturing — quote-based engineering and production of customer-specified parts — supported by in-house capabilities including hand layup, a 25-foot ASC autoclave for large-format cure, 5-axis CNC machining, laser projection, and CT scanning inspection. The secondary stream is a catalog e-commerce storefront offering 2,000+ in-stock composite panels, tubes, sheets, and accessories at fixed prices (e.g., $219.75 to $1,969.50 per panel), serving prototyping, R&D, and small-quantity buyers. Named customers include Lockheed Martin, BAE Systems, L3Harris, General Atomics, Kratos, NASA Langley, Sandia National Labs, Textron Systems, Mizuho OSI, Broncus, Paddletek, and Robertson Fuel Systems, indicating a heavy concentration in defense primes and federal agencies alongside consumer-facing sporting goods and medical device OEMs. Leadership transitioned in 2010 to the second generation of the Sparr family, with Justin Sparr as CEO and Jessica Sparr as COO, while founder George Sparr remains President.
