Carbon fiber hybrid resin matrix composite material and preparation method thereof

Abstract

The invention discloses a carbon fiber hybrid resin matrix composite material. The composite material is formed by taking a glass fiber and a carbon fiber as reinforcements, and unsaturated polyester resin, vinyl resin or epoxy resin act as base bodies; the mass percentage of the carbon fiber in the carbon fiber hybrid reinforcement is 50%-90%; the composite material is in a multi-layer laminated structure which sequentially comprises a first glass fiber reinforced composite material layer, a first carbon fiber reinforced composite material layer, a second glass fiber reinforced composite material layer, a second carbon fiber reinforced composite material layer and a third glass fiber reinforced composite material layer from inside to outside, and the layering mode is 0 degree / 90 degrees; the weaving modes of the carbon fiber and the glass fiber are one or more of plain weaving, twill weaving, satin weaving, unidirectional weaving and multi-layer multi-axial-direction weaving; meanwhile, a preparation method of the carbon fiber hybrid resin matrix composite material is provided. The carbon fiber hybrid resin matrix composite material is good in mechanical performance, is good in sound transparent property, and resists seawater corrosion.

Description

technical field [0001] The invention belongs to the technical field of resin-based composite materials, and in particular relates to a carbon fiber hybrid resin-based composite material and a preparation method thereof. Background technique [0002] In order to avoid the impact of water flow on the sonar array, a sound-permeable cover is usually arranged outside the sonar array. Underwater acoustic materials generally include sound-transmitting, sound-absorbing, and sound-insulating materials, and are mainly used for underwater equipment and acoustic transducers. The existing underwater sound-permeable materials generally fall into the following three categories: metal materials, polymer rubber materials and fiber-reinforced resin-based composite materials. As a sound-transmitting material, metal materials have the advantages of high strength and high modulus, but metal materials are materials with a large response to excited vibrations, which will generate large self-noise...

Problems solved by technology

Chinese patent CN200997679Y discloses a sound-transmitting dome, and the sound-transmitting material is a polyurethane rubber-type material; Chinese patent CN101934617A discloses a wide-band underwater sound-absorbing sound-transmitting material and its preparation method, using butyl rubber to prepare the sound-transmitting material, Both of the above two materials have good sound transmission properties, but rubber materials have low mechanical properties and require a pressurization system to maintain the shape, so they cannot be used as structural parts alone

However, the modulus of glass fiber-reinforced resin-based composite materials is low. In order to ensure the stiffness, the thickness of the composite material needs to be increased, which will affect the sound transmission performance of the material; carbon fiber-reinforced composite materials inevitably have the interaction between carbon fiber composite materials and metal materials. Contact problems, which can lead to electrochemical corrosion of carbon fiber composites
