Composite structural component and application thereof

Abstract

The invention provides a composite structural component and an application thereof. The composite structural component comprises a space truss, a coupling material and at least one layer of fiber cloth, wherein the space truss is preset as a hollow structure; the hollow structure formed by the space truss is filled with the coupling material; the at least one layer of fiber cloth covers the part,filled with the coupling material inside, of the space truss or the whole outer surface. The structural component is covered with the fiber cloth, bending resistance and torsional property of the structural component can be improved, and the covering mode of the fiber cloth can be designed, so that the anisotropic structural component with excellent mechanical properties is obtained; a temperaturecontrol component and a heat conducting component can be arranged in the coupling material and used for monitoring and adjusting internal temperature of the structural component in real time; tensilestrength, bending strength and compressive strength of the structural component can reach 3 times or more those of an iron casting, the structural component can be formed by pouring at normal temperature, can be adaptive to thermal deformation and is suitable for large-scale production and application, and the manufacturing technology is simple.

Description

technical field [0001] The invention belongs to the field of composite materials for machinery, and in particular relates to a composite material structural part and its application. Background technique [0002] In recent years, with the continuous development of the equipment manufacturing industry and the introduction of the concept of "advanced manufacturing technology", the equipment manufacturing industry has gradually developed in the direction of precision and extremeization, mainly manifested in the large-scale and small-scale high-precision manufacturing equipment. The development direction of manufacturing equipment puts forward higher requirements for the structural design of industrial equipment. Traditional industrial equipment structural parts, such as beams of gantry milling, machine tool columns, etc., mostly use isotropic metal materials such as cast iron and steel as the main materials. Process molding, there are more deficiencies. For example, the manufa...
