Project time: 2017 – 2020
Budget: 6 600 000
The transition from conventional to electric power lines creates many challenges, but also opens up new possibilities for component packing and design of load bearing structures as well as new manufacturing methods. The project aims to exploit opportunities with sandwich construction to reduce weight and hence the energy consumption for propulsion; reduce heat losses and hence energy consumption for climate change and to reduce manufacturing costs using new manufacturing concepts, rational assembly and new construction technology.
The aim of the project is therefore to contribute to increase manufacturing efficiency and reduce environmental impact by developing and verifying rational manufacturing methods for lightweight selfsupporting karos modules in sandwich elements. Sandwichteknik becomes central as a design concept, which means a technology shift for both design and Manufacturing methods. In particular, the following aspects will be studied: (i) rational linking between sandwich and monolith structure, (ii) development of methods for structural optimization of glue and adherent geometries, (iii) development and verification of rational manufacturing for net-shape PUR cores, (Iv) evaluation of net-shape molding of thermoplastic PET foam; (v) evaluation of PUR from natural raw materials; (vi) rational composition and integration of brackets and cables; (vii) development of models and methods for predictive form modification And process variability in foam materials, and (viii) new material flows for the purpose of reusing production games.
The purpose of the project is to identify and clarify both the business and technical mechanisms driving the efforts towards cost-effective volume production of fibre composites, as well as the process that enables a competitive expansion of the production in Sweden.

The project goal is to test manufacturing of a 7 m bus side using 3D litecomp technology to evauluate production rate and product properties. 3D Litecomp is a sandwich technology developed at Chalmers Industrial Technology. The technology makes it possible to manufacture strong light stiff structures in complex shapes with high-energy absorption and variable sandwich core thickness.
