FORMING THERMOPLASTIC PREPREGS IN A TEXTILE REINFORCED INORGANIC PHOSPHATE CEMENT COMPOSITE MOULD

Book Contribution - Book Chapter Conference Contribution

Thermoplastics offer a number of important advantages over thermosetting composites for example: reduction of production time, material reduction, cost saving and ecological aspects. However, forming, thermoplastic composite parts, requires high processing temperatures (+200°C). The aim of this research is the development of a mould technique which can replace the common metal moulds, using textile reinforced cementitious composites. In order to develop these thin shell type moulds shrinkage and porosity issues are studied. In this research the shrinkage of the textile reinforced cementitious composites is measured with digital image correlation. The addition of fillers reduces the matrix shrinkage by 50%. When combining this optimized matrix with textile reinforcement the thermal deformation is reduced to less than 0.5%. By adding a polyether ether ketone filler (PEEK) in the top coat the porosity problem was reduced and the surface quality improved. A hot pressing mould is made in order to evaluate the possibility of forming a Polyamide 6 (PA6) resin prepreg, reinforced with a E-Glass fibre roving at a temperature of 250°C . Parts can be formed successfully using this new moulding technique showing the potential.
