Abstract
For structural components with high specific mechanical properties frequently parts made of fibre reinforced plastics (FRP) with thermoset matrix systems, oriented reinforcement fibres and high fibre volume contents are used. An established manufacturing technique for the production of composite profiles is the pultrusion process. By custom-designed properties pultruded parts are used for example as load-bearing structures in the building sector or lining elements in the transportation industry1. The pultrusion process is characterized by high laminate qualities, a high degree of automation and an eminent economic efficiency. A further reduction of the production costs can be achieved by the use of alternative matrix systems with comparable material properties by reduced raw material costs and increased processing speeds. By the restricted reactivity of the most commonly used matrix systems the processing speeds are limited. 5 Refs.
