What CirComp does

CirComp GmbH is a German manufacturer of high-performance fiber-reinforced composite components, headquartered in Kaiserslautern. Founded in 2009 and operating as a wholly-owned subsidiary of the US-based Albany Engineered Composites, Inc., the company develops and produces custom-engineered parts and semi-finished products from carbon fiber (CFRP), glass fiber (GFRP), aramid (AFRP), and basalt fiber composites for three verticals: aerospace, marine, and industrial/mechanical engineering. Aerospace applications include structural rods, satellite structures, sensor housings, and pressure vessels; marine applications include masts, radomes, and pressure vessels; and industrial applications include rollers, shafts, bearings, and hydrogen/CNG pressure vessels. The company is certified to ISO 9001:2015, EN 9100:2018, and Nadcap, qualifying it to supply aerospace OEMs and Tier-1 suppliers.

The company's core technology platform is FilaWin®, a proprietary CNC-controlled filament winding process that achieves high fiber volume content, excellent resin impregnation, and laminate qualities with glass transition temperatures up to 400°C. Manufacturing capabilities span filament winding, thermoplastic pultrusion, and resin transfer moulding (RTM), supported by in-house quality assurance including 3D measurement, ultrasonic testing, DSC, and pressure-burst testing. Finished product lines include the patented AIRSTRUT® composite rod and strut family (qualified on A350 and A380 platforms), FilaWin® Isogrid lattice structures, FilaWin® composite retention sleeves for high-speed rotors and generators, and DExWin® carbon-fiber-PEEK bearings and sleeves. Production lot sizes range from single prototypes to over 100,000 units per dimension.

CirComp operates a direct enterprise sales model with engineering-led consultative selling, handling inquiries via a dedicated sales contact ([email protected], +49 6301 7152-11). Pricing is custom-quoted per project based on dimensions and configuration, with multi-year supply contracts typical for aerospace and naval programs. A small selection of standard CFRP tension-compression rods is listed on carbon-24.de as a reference channel for smaller buyers. The company's go-to-market is reinforced by partnerships with regional and European composites networks, including Kunststoffnetzwerk Rheinland-Pfalz, CCeV (Carbon Composites e.V.), and the Institut für Verbundwerkstoffe (IVW). No public pricing, revenue figures, or funding events are disclosed.

Core offering

CirComp GmbH develops and manufactures high-performance fiber composite components and semi-finished parts from carbon, glass, aramid, and basalt fiber reinforced plastics using CNC-controlled filament winding (FilaWin®), thermoplastic pultrusion, and resin transfer moulding (RTM) processes. The company serves aerospace, marine, and industrial customers with custom-engineered products including AIRSTRUT® rods, Isogrid lattice structures, DExWin® bearings, composite rotor sleeves, pressure vessels, masts, and CFK tubes.

Product overview

CirComp develops and manufactures high-performance composite components and semi-finished products (Halbzeuge) from carbon fiber reinforced plastics (CFRP), glass fiber reinforced plastics (GFRP), aramid fiber reinforced plastics (AFRP), and basalt fiber composites. The company operates across three industry verticals: Aerospace (AIRSTRUT® rods, propellant tanks, satellite structures, sensor housings), Marine (masts, pressure vessels, radomes), and Industry (tension-compression rods, rollers, shafts, bearings, hydraulic cylinders). The proprietary FilaWin® filament winding technology serves as the core manufacturing platform, enabling products like AIRSTRUT® structural rods, Isogrid lattice structures, DExWin® bearings, and composite rotor sleeves. Manufacturing processes include CNC-controlled filament winding, thermoplastic pultrusion, and resin transfer moulding (RTM), producing both finished components and semi-finished materials in thermoset and thermoplastic variants.
