摘要:
The present invention defines a pultrusion apparatus. The apparatus comprises a portion for receiving fibres, a portion for injecting resin into the fibres, a portion for impregnating the resin injected fibres, and a portion for shaping the impregnated fibres, wherein the fibres, following their passage through the receiving portion, converge in the resin injection portion to receive the resin and the resin flows outwards following injection as the fibres progress from the injection portion through the impregnation portion, and further wherein the fibre receiving portion comprises an inlet comprising openings of varying size in an oscillating lattice arrangement.
