A bend surface composite lattice structure and preparation method

The present invention discloses a composite lattice structure and surface preparation. The present invention uses twisted fiber bundle prepared playing lattice core fiber bundle monomer, by controlling the radius of curvature of the fiber bundle monomer fillet molding die, the weight ratio of the weight of the wheel and twist the fiber bundle is reduced the core matrix is ​​the probability of damage occurring during the molding process, effectively improves mechanical properties of the fiber bundle forming monomer; secondly, the lattice structure may be implemented with machining complex surfaces; again, through the connection point of the reinforcing panel detailed design of the surface, so that the quality of the fiber bundle directly connected with the panel monomers are improved and the quality of bonding the fiber bundle lattice panel with monomer, thereby improving the resistance to shear of the lattice structure; Finally, by designing tow monomer mold, molding a reasonable radius of curvature adjustment, parameters such as twist the fiber bundle, can be prepared lattice structure having a complex curved shape, and mass production can be realized.
