Abstract

The invention discloses an intercalation material for enhancing the interlayer performance of a continuous fiber resin-based composite board and a preparation method thereof. The intercalation material mainly utilizes the synergistic effect of polymer fiber non-woven fabrics and acicular iron oxide particles, which can effectively improve the interlayer toughness of continuous fiber resin-based composite sheets, and orient the acicular iron oxide particles with the aid of a magnetic field. arrangement to obtain a more efficient toughening effect. The specific method is: first, disperse and dissolve different raw materials such as magnetic acicular iron oxide particles, auxiliary dispersing agent, coupling agent, etc. in a suitable solvent according to a certain proportion, and then spray or dip them on the polymer fibers of a specific material. On the non-woven fabric, the magnetic needle-shaped nano-iron oxide particles are then aligned along the direction perpendicular to the surface of the polymer fiber non-woven fabric under the assistance of a magnetic field, and the final product is obtained after drying. The preparation method of the intercalation material has the characteristics of simple process, low cost, safety and environmental protection, and high production efficiency.
