Abstract

The invention discloses a device and a method for preparing a discontinuous fiber orthogonally-reinforced composite material, and relates to the field of preparation of discontinuous fibers. The problem that fibers of an existing composite material are not strictly coplanar is solved. One set of opposite sides of a porous core plate is connected with a double-groove arc-shaped plate, and the otherset of opposite sides of the porous core plate is connected with a single-groove arc-shaped plate. Movable positioning piles are arranged at the positions of two grooves of the double-groove arc-shaped plate. The preparation method is achieved through the following steps that marking is conducted on hole array paper; an inner-layer resin film is placed; the hole array paper is placed; laying of acolumn of discontinuous fibers is completed; turning to the initial laying position of the next column of fibers is conducted; after the fibers are laid in one direction, the fibers are coiled at theend part of the single-groove arc-shaped plate and are turned to the movable positioning piles at the end part of the double-groove arc-shaped plate; discontinuous short fibers in the orthogonal direction are laid; after laying is finished, turning to laying of the next column of fibers is conducted; after laying is completed, an outer-layer resin film is placed outside a fiber layer; and composite forming of composite material is completed.

Description

technical field [0001] The invention relates to the field of preparation of discontinuous fiber reinforced composite materials, in particular to a preparation device and method of discontinuous fiber orthogonally reinforced composite materials. Background technique [0002] Composite materials reinforced with discontinuous fibers in orthogonal directions exhibit high strength in two orthogonal directions, but less strength in other directions. This structure can ensure that the strength of the two orthogonal directions meets the application requirements, and does not lay fibers in other directions that do not require high strength. Therefore, the amount of fiber used can be reduced and the material cost can be reduced. This laid composite material is widely used on pressure vessels. [0003] The conventional method for preparing composite materials reinforced with discontinuous fibers in the orthogonal direction is to laminate two single-layer thin plates whose reinforcing...
