Nylon 66 glass fiber composite material with high glass fiber content and preparing method thereof

The invention discloses a nylon 66 glass fiber composite material with the high glass fiber content and a preparing method thereof. According to the nylon 66 glass fiber composite material, nylon serves as a matrix, high-content glass fibers serve as reinforcing materials, hollow glass microspheres serve as an auxiliary filling agent, and an interface bonding agent and other assistants are added; the auxiliary filling agent is in a rolling-ball shape, the liquidity of the composite material can be improved, and processing performance is improved; the interface bonding agent comprises two parts, one end of the interface bonding agent is anchored and sucked to the surface of the glass fibers, the other end of the interface bonding agent can be wound around nylon molecular chains outwards, and the effective space stability effect is achieved. By means of the nylon 66 glass fiber composite material and the preparing method thereof, the interface bonding performance of the glass fibers and the nylon is improved, t
