Abstract

An apparatus and a method for preparing a multi-directional continuous fiber-reinforced composite material. The apparatus includes an electrostatic fiber-splitting device configured to controllably split a fiber bundle, a powder spreading device configured to spread a powder, and a pre-press molding device configured to cut the fiber and compact the powder. The electrostatic fiber-splitting device includes a rotatable fiber-splitting table. The pressing plate is controlled by an electromagnet, and the pressing plate is energized to generate a high-voltage electrostatic field to disperse the continuous fiber bundle into monofilament fibers.
