The invention discloses a fast resin
wetting forming technology based on
material flow prepeak monitoring on the basis of a traditional resin
wetting forming technology. A
system comprises a monitoring module, a
vacuum pump, a vacuum tank, a sensor, electromagnetic valves A, electromagnetic valves B, a throttling valve, a die, a
storage tank, filler, die releasing cloth, a flow guide net, a flow guide
pipe, a pipeline connecting piece, sealing cloth, a feeding pipeline, a middle pipeline and a gas extraction pipeline. The technology process mainly includes the steps that the die is divided into multiple filling areas; the
material flow prepeak position is monitored through the sensor in the monitoring module; sequential starting and stopping of all the pipelines are controlled in cooperation of a controller, and step-by-step filling is achieved for the different filling areas; and after all the areas are filled with
sizing materials, curing forming is conducted, then die releasing is conducted, and a product can be obtained. Compared with a traditional technology, the fast resin
wetting forming technology has the beneficial effects that
sizing material prepeak lossless monitoring is achieved, and the
automation degree is high; and the probability of filling defects such as incomplete wetting can be better lowered, and meanwhile the labor cost is reduced. The fast resin wetting forming technology is particularly suitable for
processing and producing of various large thermosetting
resin matrix composite materials of complex structures.
