Non-metallic materials

From the spring Semester 2010 the courses Materials Technology is fused with the course Ceramics. The new course, “Non-metallic Materials Technology” deals with polymeric, ceramic and composite materials.

A brief summary is given in the course on the structure and properties of polymers, with emphasis on their viscoelastic nature. A summary of the structure and properties of ceramics. A discussion on the basic properties of composites as functions of their composition.

Then we will talk about the forming processes of polymers and composites and over the firing of ceramics.

composites

Sat, 2 Jan 2010 18:33:49 +0200

Definition: A mixture of two or more materials that when put together present a useful combination of properties. E.g., two brittle materials, such as glass fibres and a polyester can be combined to form a tough composite with very good mechanical properties.
Some historical composites are:
•  Mud reinforced with straw (adobe)
•  Paper
•  Rubber reinforced with wire or cotton
•  Cement reinforced by asbestos
•  Reinforced concrete
•  MDF

This course gives an introduction in the concept of “materials”; we examine the structure of the several classes of materials and how this determines their properties; the failure mechanisms of structural materials; their properties and how they are affected by processing; the environmental effects in short and long term properties. Further, the necessity is underlined of an organised technoeconomic approach in the management of materials during the useful lifetime of the products and the recycling afterwards.

The goal of the course for the future engineer is to learn how to choose the appropriate material for a certain application or product and to be able to discern the applicability and the limits for the application of a certain material and how its properties can change during or after its manufacturing.
