Abstract

The invention discloses a preparation method of a truss core structure of truss-like composite, relates to a preparation method and aims to solve the problem that conventional domestic and foreign assembly technologies are complex in steps, small in joint binding area and low in the possibility of core integral molding. The preparation method comprises the following nine steps: step 1, pre-treatment of a hot pressing mold; step 2, preparation work of a corrugated plate; step 3, preparation work of panels; step 4, cutting work of the corrugated plate; step 5, pre-treatment work of ripple strips; step 6, bonding work of a coating and the ripple strips; step 7, locating of the placement of the ripple strips on the panels; step 8, bonding work of a truss-like configuration and the panels; step 9, putting the truss-like composite configuration in a drying oven to solidify the coating. The invention prepares the truss core structure of truss-like composite.

Description

technical field [0001] The invention particularly relates to a preparation method of a lattice core structure of a truss-like composite material. Background technique [0002] Composite materials are composed of two or more materials with different properties through physical or chemical methods to form materials with new properties on the macro (micro) level. Composite materials have many advantages that other materials do not have, such as high specific strength, high specific modulus, good designability, simple manufacturing process, good thermal stability and good high temperature performance. Different types of composite materials also have different excellent properties. , such as fatigue resistance, impact resistance, electromagnetic wave permeability, vibration damping and corrosion resistance. Composite materials are widely used. In the field of aviation, composite materials have been applied to aircraft fuselage, wings, cockpits, propellers, radomes, and wing surf...
