At JEC World 2026, Plasmatreat GmbH will be presenting plasma technology for the industrial pretreatment of composite materials in Hall 5, Stand G65, in Paris from 10 to 12 March. The focus will be on applications in aerospace, automotive engineering and industries where fibre-reinforced plastics and hybrid material systems are used. Visitors will learn how CFRP and thermoplastic components are prepared with plasma for processes such as bonding, painting or sealing.
Lightweight composite materials such as carbon fibre reinforced plastics (CFRP), thermoplastics and hybrid structures are increasingly being used in industry to reduce weight and increase efficiency. These materials often have low surface energy, which makes it difficult for adhesives, coatings and sealants to bond reliably and requires surface treatment prior to processing. Conventional methods such as mechanical grinding or the use of chemical primers often reach their limits in this regard.
Plasmatreat’s open-air plasma technology operates under atmospheric pressure conditions and enables selective, reproducible surface cleaning and activation using compressed air and electrical energy. This removes organic contaminants and increases surface energy without altering material properties. One application in the open air sector is HydroPlasma, in which distilled water is introduced into the plasma jet to remove organic and inorganic residues without damaging the material surface. In addition, nano-thin layers can be applied at atmospheric and low pressure as environmentally friendly bonding agents.
Large-area treatments and selective applications are possible, for example in adhesive grooves. The improved adhesion can extend resistance to corrosion, erosion and mechanical stress. Plasmatreat’s plasma processes do not require solvents or VOCs, do not produce hazardous waste and can be integrated into existing production environments.
