LMAT

What LMAT does

LMAT LTD is a Bristol, UK-based private engineering firm founded in 2009 by Tomasz Garstka that develops software and consultancy services for composite manufacturing process simulation. Its core product is the Advanced Composite Cure Simulation (ACCS) software suite, which predicts cure-induced residual stresses, mould pressures, exotherms, temperatures, and component distortion for thermoset and thermoplastic composites across processes including resin infusion, press moulding, and pultrusion. ACCS is distributed globally as a module within the ANSYS CAE platform and is also delivered as customised versions with material cards for ABAQUS and LS-DYNA; ancillary products include paint cure prediction software and the Gate Control System, a PLC-and machine learning-based monitor and controller for multi-gate infusion.

The company runs an in-house material characterisation laboratory in Bristol covering thermoset, thermoplastic, permeability, and squeeze flow testing, generating proprietary material databases that feed ACCS. Services span material characterisation, process simulation, tool design, and tool surface compensation, with documented delivery of compensated tools for several hundred aerospace structural components. Customers are primarily composite manufacturers in aerospace, wind energy, automotive, and the emerging hydrogen economy, served through project-based consultancy, direct enterprise engagement, and software licensing via ANSYS. GD-compliant and founder-led, LMAT has no disclosed institutional ownership or external funding.

Core offering

LMAT develops and licenses the proprietary Advanced Composite Cure Simulation (ACCS) software suite for predicting cure behaviour, residual stresses, mould pressures, temperatures, exotherms, and component distortion in thermoset and thermoplastic composites. The company pairs this software with in-house material characterisation testing and specialist engineering consultancy covering process simulation, tool design, tool surface compensation, resin flow analysis, and PLC-based automation systems, primarily serving aerospace, wind energy, and automotive manufacturers.

Product overview

LMAT offers a unified platform of software products and engineering services for composite manufacturing process simulation. The core offering is the Advanced Composite Cure Simulation (ACCS) software, which is available both as standalone and integrated with mainstream CAE platforms (ANSYS ACCS, with custom cards for ABAQUS and LS-DYNA). Complementary products include material characterisation services that generate comprehensive material cards feeding into simulations, and specialized engineering solutions for cure distortion and tool compensation. Supporting services include process simulation consulting, automation systems with PLC-based control and machine learning-powered Gate Control for infusion monitoring, resin flow simulation, tool design, and tool compensation. The portfolio is designed to deliver accurate, compensated tooling right first time, eliminating trial-and-error manufacturing approaches.
