Title:
METHOD AND MOULDING SYSTEM FOR MANUFACTURING A FIBRE-REINFORCED POLYMER OBJECT VIA A FEEDBACK SYSTEM FOR CONTROLLING RESIN FLOW RATE
Document Type and Number:
WIPO Patent Application WO/2014/006131
Kind Code:
A3
Abstract:
A method of manufacturing a fibre-reinforced polymer object (5) by means of vacuum- assisted resin transfer moulding (VARTM), wherein fibre material (16) is impregnated with liquid resin in a mould cavity (44) comprising a rigid mould part (13) having a mould surface(14) defining an outer surface of the object, is described. One or more pressure sensors (60) are connected to resin inlets (27, 27') of the VARTM system. A control unit (62) is used for controlling a polymer supply unit (64) based on measured resin pressure and is adapted to adjusting a resin flow rate, if pressure measured by the pressure sensors is below a lower threshold level or above a higher threshold level.
