<p>Method of impregnating fibres reinforcement with polymer material including the steps of: mixing the polymer material in particle form with a liquid in which the polymer material does not dissolve to form a dispersion; and impregnating the fibres reinforcement with the dispersion. The fibres reinforcement is said to be dried after impregnation with the dispersent. The use of the processes described with any polymer material is disclosed, however, the preferred polymers are said to be thermoplastics materials such as polysulphone, polyethersulphone, polyetheretherketone, polyetherketone, polyetherimide, polystyrene, polyphenelene suphide and polyamides. Any suitable liquid dispersant having a boiling point below the glass transition temperature of the thermoplastics material may be used and water is said to be preferred for the polymers enumerated. The particle size of the polymer used is said to vary in accordance with the characteristics of the fibres reinforcement used but a typical particle size not exceeding 5 microns is disclosed. The specification discloses in addition articles made from a fibres reinforced polymer material as described.</p> |
