Infinite Composites

Infinite Composites is a specialist design and manufacturing firm positioned in the aerostructures and propulsion supply chain. The company focuses on the development of high-pressure storage solutions, specifically linerless composite pressure vessels (LCPVs). These systems are designed to store cryogenic and non-cryogenic fluids, such as liquid oxygen and hydrogen, while reducing the weight penalty typically associated with traditional metallic or lined composite tanks. Their work supports the transition toward lightweight fuel systems in both atmospheric flight and orbital transport. While the company operates as a tier-two or tier-three supplier, its technology is primarily directed toward the NewSpace sector and advanced air mobility platforms. They have engaged with government agencies, including NASA, to demonstrate the viability of linerless structures for space exploration and launch vehicle components. Their output includes conformable tanks and spherical vessels designed to withstand extreme thermal gradients and high-stress environments common in rocket propulsion. Prospective buyers should verify the specific pressure ratings and fluid compatibility certifications for their intended application, particularly for reactive or ultra-low temperature propellants. It is essential to confirm the current Technology Readiness Level (TRL) of their linerless designs relative to specific airworthiness or spaceflight qualification standards. Technical due diligence should focus on permeability rates and cycle life data for the specific resin systems and carbon fibre filaments employed in their manufacturing process.
