Aims

Obtaining elemental teoretical knowledge in composites materials. Introduction to new composite materials used in the building industry. Understanding of composite effects of materials and of possibilities which offers the composite material. Introduction to principles of composites design and utilization. The student can on the base of obtained results make the optimal choice of the composite material for actual application and he is able to define the demanded properties of composite material and conditions for its use. He is able to predict the properties of designed composite material.
