Abstract: A method of manufacturing a fibre-reinforced polymer object by means of vacuum-assisted resin transfer moulding (VARTM), wherein fibre material is impregnated with liquid resin in a mould cavity comprising a rigid mould part having a mould surface defining an outer surface of the object, is described. One or more pressure sensors are connected to resin inlets of the VARTM system. A control unit is used for controlling a polymer supply unit 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.

Abstract translation: 一种通过真空辅助树脂传递模塑（VARTM）制造纤维增强聚合物物体的方法，其中纤维材料在模具腔中浸渍有液体树脂，该模腔包括刚性模具部件，该模具部件具有限定外表面的模具表面 对象，被描述。 一个或多个压力传感器连接到VARTM系统的树脂入口。 控制单元用于基于测量的树脂压力来控制聚合物供应单元，并且如果由压力传感器测量的压力低于低阈值水平或高于较高阈值水平，则适于调节树脂流量。
