Abstract

The invention provides a carbon paper composite material for laser lamination molding and a preparation method thereof, which is composed of the following raw materials in the following mass ratio: 5-20 parts of carbon paper, 80-95 parts of resin matrix, coupling agent 1-5 parts, 0.5-3 parts of antioxidant, 0.5-5 parts of heat stabilizer and 0.5-5 parts of lubricant. The carbon paper composite material for laser lamination prepared by the present invention has the characteristics of simple preparation process, high mechanical strength, fast forming speed and low water absorption rate, greatly shortens the production cycle and reduces costs, and can be directly applied and promoted in In the field of laser lamination manufacturing technology, it can be directly processed into structural parts.

Description

technical field [0001] The invention belongs to the technical field of laser lamination molding, and in particular relates to a carbon paper composite material for laser lamination molding and a preparation method thereof. Background technique [0002] Laser lamination technology relies on CAD simulation technology and computer control technology. The feeding system transports the raw materials to the workbench in sections, cuts the foil along the vertical and horizontal directions to the desired contour, and finally compresses the multi-layer foil by a hot press Three-dimensional artifacts are obtained. This molding technology has the characteristics of fast molding speed, no support structure and no pollution, and can directly prepare large-sized parts. [0003] But at the same time, the existing materials of laser lamination technology are mainly composite materials such as paper, resin materials and clay, which have shortcomings such as few types of raw materials to cho...
