Abstract [en]

The demands on fuel efficiency and environmental friendliness of cars have driven the automotive industry towards composite materials which reduce the weight compared to the traditional aluminum and steel solutions. The purpose of this master thesis is to evaluate the possibility and feasibility of redesigning a high volume metal chassis part in composite materials.  To accomplish this the thesis work was divided into two parts. The first part consists of a composite study which explores the available composite technologies in the industry such as implemented chassis components and available manufacturing methods. The composite study shows that almost no high volume chassis component in the market are made out of composites, with exception to leaf springs. In the industry there are many different composite manufacturing methods but in general the most ready for high volume production are Injection molding, compression molding and RTM. A method was also explored to efficiently evaluate different material and manufacturing methods against each other. By knowing the critical requirement both materials and manufacturing methods can be evaluated separately against each other. The second part consists of a design phase where the knowledge from the composite study was used to choose and redesign a chassis component in composite. A motor mount was chosen and redesigned using injection molding. The new design shows that a weight decrease of at least 38% is possible without significant cost differences.
