Carbon fiber composite material forming device and method

Abstract

The invention relates to a carbon fiber composite material forming device and method. The carbon fiber composite material forming device comprises an electromagnetic rod body, an elastic outer mold, a magnetic chamfering strip, a centering seat body, a first outer buckling mold and a second outer buckling mold. The elastic outer mold covers the electromagnetic rod body; centering bases are oppositely arranged at the two ends of the electromagnetic rod body. The centering seat body comprises a centering rotating shaft, a return elastic body, a traction rope, a guide groove plate and a shell; the centering seat body is connected with the electromagnetic rod body through the mounting hole; the return elastic body is sleeved on the centering rotating shaft; the guide groove plates are arranged on the shell at intervals around the axis of the centering rotating shaft; one end of the traction rope is fixed, and the other end is connected with the magnetic chamfering strip; one end of the shell protrudes to form a fixed clamping edge; the first outer buckling die and the second outer buckling die are buckled with each other, and two ends are respectively contacted with the fixed clamping edges. The high-cost design in the form of an autoclave is avoided, and the molded composite pipes can be effectively ensured to be consistent in appearance and good in performance uniformity.

Problems solved by technology

In this process, on the one hand, because the length of the pipes is often made longer, and the mechanical fixed fastening method is basically adopted for the male and female membranes, the force on the abrasive tool is often uneven, resulting in different pressures on different areas of the pressing molding. It affects the mechanical properties of the formed composite pipe. On the other hand, because the air pressure is used for pressing, the air pressure will cause local pressure differences due to mechanical fixation, and it is also difficult to design for the inflatable mold. In addition Due to the existence of air pressure difference, it is easy to produce wrinkles during the production process, which affects the performance of composite pipes
