Abstract

The invention discloses a glass fiber and carbon fiber mixed reinforced polyester mineral composite material and a preparation method thereof, which belong to the technical filed of composite materials. The glass fiber and carbon fiber mixed reinforced polyester mineral composite material comprises an adhesive substrate, an aggregate, a glass fiber and a carbon fiber, and is prepared by the steps of evenly mixing the adhesive substrate, the aggregate, the glass fiber and the carbon fiber, casting and curing the mixture, and the like, wherein the mass fraction of the adhesive substrate is 9 to 20 percent; the mass fraction of the aggregate is 79 to 90 percent; and the sum of mass fractions of the glass fiber and the carbon fiber is 0.1 to 1 percent. The composite material has excellent damping property and physical and mechanical properties, improves the compressive strength by 25 to 35 percent compared with a polyester mineral material without reinforced fiber, improves the damping ratio by 8.5 to 21 percent, and can be used as an excellent mechanical basic element material.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a glass fiber and carbon fiber mixed reinforced polyester mineral composite material and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] The development of modern science and technology has higher and higher requirements for machining efficiency, precision and quality. High speed and high precision have become the two major development trends of modern machining technology. It is required to shorten the processing time and auxiliary time, and increase the metal removal rate and cutting amount. . The increase of cutting amount is easy to cause vibration in the process of machining, so the machine tool system is required to have better dynamic and static performance, thermal stability, high damping and other performance. The main way to solve the vibration problem is to optimize the machine...
