Forming tool for carbon fiber composite material landing gear strut

Abstract

The invention discloses a forming tool for a carbon fiber composite material landing gear strut. The forming tool comprises an upper tank body, a lower tank body, a telescopic rod, a base, a hinged piece, a die frame and a core die. The hinged piece is connected between the upper tank body and the lower tank body, and the die frame and the core die are correspondingly arranged on the upper tank body and the lower tank body respectively. The upper end of the telescopic rod is connected into the upper tank body, and the lower end of the telescopic rod extends to the inner side of the lower tank body. A fan and an air inlet device are arranged on the surface of the base, and the fan is located on one side of the air inlet device. A heating assembly is laid on the periphery of the die frame, a cooling assembly is fixedly installed below the heating assembly, a heat preservation frame is movably installed above the heating assembly, and a lighting device is arranged at the bottom of the die frame. The forming tool has the beneficial effects that demolding is not likely to happen, popularization is made convenient, then the problems of laying, pressurizing curing and demolding of the landing gear composite material strut are solved, and molding manufacturing of a double-curvature variable-cross-section, multi-layer-number and large-thickness composite product of a special structure is achieved.

Description

technical field [0001] The technical field of carbon fiber equipment of the present invention, in particular, relates to a forming tool for a landing gear pillar made of carbon fiber composite material. Background technique [0002] Carbon fiber composite materials have been widely used in military technical fields such as aerospace and weaponry due to their light weight, high strength, high modulus, and corrosion resistance. In order to ensure their strength requirements and porosity requirements, traditional high-performance composite materials , Most of them use the autoclave molding process. The advantages of autoclave forming are that it can manufacture various complex components, the quality of the parts is excellent, the forming precision is high, and the thickness of the parts is uniform. [0003] However, because the main landing gear strut structure is a double-curvature variable cross-section design with lateral bending, wide top and narrow bottom, and the main l...
