Carbon fiber composite material reciprocating compressor valve plate and preparation method thereof

Abstract

The invention discloses a reciprocating compressor valve plate made of carbon fiber composite and a manufacturing method of the reciprocating compressor valve plate made of the carbon fiber composite. The valve plate is in the shape of a long strip, the two ends of the valve plate are semicircular, a hole which is connected with a valve seat of a reciprocating compressor is formed in one end of the valve plate, carbon fibers are arranged in the mode that the included angles between the carbon fibers and the length direction of the valve plate are 0 degree, +45 degrees and -45 degrees according to the thickness of the needed valve plate, the carbon fibers are symmetrically laid layer by layer with a central layer as a plane of symmetry until the thickness of the carbon fibers reaches a preset value, and the number of layers of the carbon fibers is an even number. When the reciprocating compressor valve plate made of the carbon fiber composite is manufactured, according to a set fiber laying method, the carbon fibers and curing resin are mixed in a set laying direction, curing is conducted at the temperature between 120 DEGC and 200 DEG C, and pressing force is applied to a laminated plate during curing for compression, wherein the reciprocating compressor valve plate comprises, by volume, 60%-80% of carbon fibers and 20%-40% of curing resin. According to the reciprocating compressor valve plate made of the carbon fiber composite and the manufacturing method of the reciprocating compressor valve plate made of the carbon fiber composite, noise of the reciprocating compressor can be effectively lowered, the fatigue resistance of the valve plate is improved, and strength requirements of valve plates in different shapes can be met according to the different distribution angles of the carbon fibers.

Description

technical field [0001] The invention relates to a valve plate and a preparation method thereof, in particular to a carbon fiber composite material reciprocating compressor valve plate and a preparation method thereof. Background technique [0002] Carbon fiber-reinforced composite materials are increasingly popularized and applied due to their high specific strength, high specific modulus, and structural designability. It is widely used in many fields such as manufacturing. Due to the designability of its structure and the diversity of application objects, the manufacturing methods of composite components also have great differences. Reciprocating compressor valve plates are currently mainly made of metal materials, and metal material valve plates have the disadvantages of high noise and low fatigue resistance. [0003] There are many studies on reciprocating compressor valves at home and abroad, such as the "compressor valve" proposed by Chen Zhe, LG Electronics (Tianjin)...
