Abstract

The invention discloses a device for controlling the gel content of an in-situ solidification fiber placement machine. The device comprises a resin-supplying control mechanism, a gel-extruding mechanism, a tension control mechanism and a flow control mechanism, wherein, the resin-supplying control mechanism is arranged above the gel-extruding mechanism; the tension control mechanism is arranged at the front end of the gel-extruding mechanism and used for adjusting the system tension of the device; the flow control mechanism is arranged at the bottom of the resin-supplying control mechanism and used for controlling the flow of resin pouring onto the glass fiber; and the flow control mechanism is used for pouring the resin onto the glass fiber, and the gel-extruding mechanism is used for extruding the resin on the glass fiber into the glass fiber. The invention has the advantages of simple structure, convenient use and low cost, and the invention can realize the accurate control over the gel content of glass fiber and carbon fiber by controlling the temperature of the resin-supplying groove, the flow of the flow control groove, the clearance of the gel-extruding mechanism and the tension of the fiber on a real-time basis.

Description

Technical field:

[0001] The patent of the invention relates to the field of composite material manufacturing, and is specially used for the glue content control device of in-situ photocuring or electron beam curing fiber-reinforced composite materials. Background technique:

[0002] Fiber placement machine is one of the automatic forming and manufacturing technologies of resin-based composite materials. It is an important equipment in the manufacture of composite parts such as carbon fiber and glass fiber. The control of glue content has a significant impact on the performance of composite parts. Existing glue content control methods include mechanical extrusion, squeegee scraping, and solvent method. These traditional glue content control methods play a certain role in glue content control, but they do more damage to fibers. Large, the glue content control accuracy is not high, and the control range is small. These deficiencies above have affected the improvement of the pe...
