Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] refer to figure 1 , a carbon fiber-reinforced resin-based composite material electric current heating LOM manufacturing device, including a prepreg tape 2 of carbon fiber-reinforced resin-based composite material rolled on an unwinding barrel 1, after the prepreg tape 2 is released from the unwinding barrel 1 The lower working platform 9 or semi-formed member 10 is bonded, the upper platen mechanism 3 is pressed and energized and solidified, and the upper laser emitter 4 is cut and wound on the winding barrel 8.

[0019] The working platform 9 can move up and down along the vertical Z axis.

[0020] The plate pressing mechanism 3 includes a middle insulating plate 3-3, the two ends of the middle insulating plate 3-3 are connected with a positive electrode 3-2 and a negative electrode 3-5, and the positive electrode 3-2 is provided with a positiv...

Abstract

The invention relates to a method and device for manufacturing a carbon fiber reinforced resin matrix composite material current heating LOM, wherein a prepreg tape of the carbon fiber reinforced resin-based composite material is conveyed to the upper part of a working platform, the working platform is moved upward to fit the prepreg tape, a pressing plate mechanism moves downwards to press the prepreg tape on the working platform, at the same time, the electrodes at both ends of the pressing plate are powered on the prepreg tape of a pressing area, the pressing plate mechanism is moved upwardaway from the prepreg tape after the prepreg tape is heated and solidified, a laser emitter cuts the prepreg tape along the cross-section of the three-dimensional model, the outer part of the cross-section is cut into fine pieces, and after the cutting is finished, the working platform descends off the prepreg tape, and then the whole prepreg tape is conveyed to the upper part of the working platform, the residual prepreg tape is retracted by a winding drum after being cut, that is, the single-layer forming and solidifying is completed, a process is recycled until the forming and solidifyingof the whole three-dimensional solid component is completed, that is, the required three-dimensional solid component is obtained; the forming mode is rapid and unsupported; the solidifying technologyis low in consumption and energy-saving.

Description

technical field [0001] The invention relates to the technical field of forming fiber-reinforced resin-based composite materials, in particular to a method and device for manufacturing a carbon fiber-reinforced resin-based composite material current heating LOM. Background technique [0002] Carbon fiber reinforced resin-based composite materials have many advantages such as high specific modulus, high specific strength, fatigue resistance, corrosion resistance, good shock absorption, and designable performance. unique role. There are many traditional molding processes for carbon fiber reinforced resin-based composite materials, such as manual lay-up molding, resin transfer molding, fiber winding molding, etc. The accuracy, shape, and structural strength of composite components formed by each process method or performance are uneven. , and there are many problems such as low degree of automation, poor precision, and size and shape restrictions. The traditional curing techno...
