Publication number: 20230241863Abstract: Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.Type: ApplicationFiled: April 3, 2023Publication date: August 3, 2023Inventors: Eric Le Gall, Frederic Ostrowsky, Denis Souvay

Patent number: 11180199Abstract: A system of connected body elements for a motor vehicle includes a first body element and a second body element. The first body element has at least one duct on a surface, wherein a shoulder is formed next to the duct. The system furthermore includes an adhesive which is arranged at least partially in the duct and at least partially on the shoulder and adhesively bonds the first body element to the second body element. A connection region, directly adjoining the shoulder, of the surface of the first body element is free here from adhesive. A first space between shoulder and second body element and a second space between connection region and second body element are open towards each other.Type: GrantFiled: June 21, 2018Date of Patent: November 23, 2021Assignee: SIKA TECHNOLOGY AGInventors: Noah Munzinger, Denis Souvay, Urs Rheinegger
