Aim
The objective of the course is to introduce the students to the materials used in light constructions, e.g. light metals and composites. Focus will be on polymer matrix composites, but also the light metals Ti, Al, and Mg and other types of composites will be discussed.

Manufacturing methods, heat treatments, properties, and environmental aspects will be discussed in the course. Special focus will be on dimensioning methods for composites, especially laminate theory.

Knowledge and understanding
For a passing grade the student must

• know the most common types of Ti-, Al- and Mg alloys, how they are manufactured and heat treated, and their properties.

• know the different types of composites, and what materials are used as fibers and matrix.

• know the manufacturing methods, properties and the dimensioning methods for composites.

Skills and abilities
For a passing grade the student must

• be able to do a material selection for light constructions.

• be able to dimension a composite laminate with respect to stiffness and strength.

Judgement and approach
For a passing grade the student must
