Increasing interest about composite materials and their use in the field of civil engineering offers possibility for development of new innovative materials, which will be used as constructive elements. Use of the fiber reinforced polymers as bearing materials in the field of civil engineering is the major leader in scientific research in the recent years. The concept of the composite materials itself, offers possibility of effective exploitation of mechanical characteristics of the separate components till their limit, even in the design process. Mechanical characteristics of each composite material depend on its components. In this paper experiments of different series composite materials, which are different according to used reinforcement and matrix, are presented. Designed mechanical characteristics of different types of composite materials are discussed in dependence on their components at indoor and elevated temperature.
