Environmentally friendly and energy efficent pultrusion

该项目的目的是开发一种新的环保拉挤技术，并允许对新树脂系统（如定制配方聚氨酯）进行评估。在常规工艺中，将增强纤维浸渍在树脂浴中，然后通过加热模具使树脂交联并形成拉挤部件。在新的制造技术中，树脂的成分将存储在单独的容器中，并使用定制设计的聚氨酯树脂成分输送系统按需泵送。高效和有效的纤维浸渍将通过高效的纤维铺展和注射头的新组合来实现。这种新的制造技术的绿色证书将使用生命周期评估进行评估。

The aim of this project is to develop a new pultrusion technique that is environmentally friendly and one that permits new resin systems such as custom formulated polyurethanes to be evaluated. In the conventional process, the reinforcing fibres are impregnated in a resin bath and then passed through a heated die to cross link the resin and to shape the pultruded component. In the new manufacturing technique, the components of the resin will be stored in separate containers and pumped on demand using a custom designed polyurethane resin component delivery system. Efficient and effective impregnation of the fibres will be achieved using a novel combination of efficient fibre spreading and an injection-head. The green credentials of this new manufacturing technique will be assessed using life cycle assessment.
