Abstract

The invention discloses a continuous fiber toughened ceramic matrix composite material additive manufacturing device. A material forming area is arranged on the upper surface of a seat frame, a stereospace moving frame is arranged on the seat frame, a fiber spraying device is arranged on the stereo space moving frame, a fiber extrusion head right faces the material forming area, and a base plateis further mounted on the seat frame; and the base plate is connected with a base plate motor in a transmission mode through a base plate guide rail, the base plate is located over the material forming area, the base plate motor can drive the base plate to move downwards to be pressed on the material forming area, a scraper linear guide rail is arranged on a working face, a scraping cutter is mounted on the scraper linear guide rail, the scraping cutter can slide on the scraper linear guide rail, and a UV-LED light source is fixed below the material forming area. The continuous fiber toughenedceramic matrix composite material additive manufacturing device conducts the digital control over an internal structure of a ceramic material, through the alternating work of the scraping cutter, thefiber extrusion head and the base plate, the long fibers are embedded into a ceramic matrix in a regular mode, the internal structure of the ceramic material is improved greatly, and the precision and forming rate of the product are improved.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, in particular to a digital light processing (Digital Light Processing) additive manufacturing device combining ceramic composite materials and continuous fibers, specifically, a continuous fiber toughened ceramic matrix composite material additive manufacturing Device and method of manufacture thereof. Background technique [0002] Ceramic materials are widely used in the fields of communication, electronics, aviation and aerospace because of their high strength, high wear resistance and high corrosion resistance. However, its fatal shortcomings in brittleness and plasticity also greatly restrict the development of this type of material. The use of continuous fiber-reinforced ceramic materials can solve this problem well. Traditional processing techniques generally use sol-gel methods, direct oxidation deposition methods, and chemical vapor phase methods to prepare continuous fibe...
