Purpose and goal

To further enhance the use of structural adhesives in OEM applications, this projects investigates graphene modified structural adhesives. In this framework, the project aims to use graphene to enhance process and material properties of structural adhesives used in the automotive industry. Specifically, the project will tailor: (a) the adhesive composition (b) graphene functionalization/treatment (c) the processing flow induced anisotropy in order to deliver superior (1) electrical, (2) thermal, (3) mechanical and (4) curing properties.

Expected results and effects

In order to combine high performance and lightweight technology, modern automotive car bodies include a wide range of materials, e.g. mild steel, boron steel, aluminium, metal sandwich composites etc. Thus, joining methods are critical for car performance, especially safety and durability.

Planned approach and implementation

The project brings together a cross-functional project group consisting of: -a strong global automotive company Volvo Cars, together with CEVT -a growing SME, the composite manufacturer Lamera AB -strong scientific expertise in graphene composites from Chalmers and RISE - Research Institutes of Sweden -a strong partner for cooperation with industry, Chalmers Industriteknik -as well as adhesive manufacturers (Dow Automotive and Sika) with expertise in formulation and properties of adhesives.
