Vacuum compression molding device for carbon fiber composite

Abstract

The invention discloses a vacuum compression molding device for a carbon fiber composite. The vacuum compression molding device for the carbon fiber composite solves the problem that the performance of a carbon fiber composite molded test piece is poor and comprises an upper mechanism, a lower mechanism, a vacuumizing device, a temperature control device, a pressure control device and a numerical control operation platform. The upper mechanism is installed at the top end of guide posts installed in the lower mechanism through an upper heat conducting plate. Top-pasted type pressure sensors of the pressure control device adhere to the bottom face of the upper heat conducting plate and are connected with the numerical control operation platform through wires. Bottom-pasted type pressure sensors of the pressure control device adhere to a lower heat conducting plate and are connected with the numerical control operation platform through wires. Upper temperature sensors of the temperature control device adhere to the two sides of an upper male die of the upper mechanism and are connected with the numerical control operation platform through wires. Lower temperature sensors of the temperature control device adhere to the two sides of the upper surface of a lower female die and are connected with the numerical control operation platform through wires. The vacuumizing device is installed on a vacuum compression molding device base on the left side of the lower mechanism, and a one-way valve of the vacuumizing device is installed on the lower female die. The numerical control operation platform is installed on the right side of the lower mechanism.

Description
