<p>The invention relates to a process for making a prepreg consisting of 90-10 % (wt) fibrous reinforcing material and 10-90 % (wt) thermoplastic matrix material by impregnating the fibrous reinforcing material with a dispersion containing thermoplastic material obtained by emulsion polymerization or suspension polymerization, wherein the emulsion polymerization or suspension polymerization is terminated before the thermoplastic particles have an average particle size exceeding the diameter of filaments of the fibres of the fibrous reinforcing material and the dispersion consists of thermoplastic particles in water. A prepreg obtained by applying a process according to the invention can be used for the production of all kinds of composite moulded parts that can be used in, for instance, automotive, aerospace, home furnishing and construction articles, as well as in sports goods such as bicycles and surfing gear, boats, electrical housings, etc.</p> |
