Porcelainized glass fiber prepreg and preparation method of power battery box

The invention discloses a porcelainized glass fiber prepreg and a preparation method of a power battery box, and belongs to the field of battery box preparation, and the preparation method comprises the following steps: preparing a resin matrix; preparing a fiber fabric; impregnating the prepared resin matrix and the fiber fabric by adopting a hot melting method to obtain a prepreg; cutting the prepared prepreg by using an automatic fabric cutting machine; according to the porcelainized glass fiber prepreg compression molding box body, the compact fabric woven by continuous fibers is adopted as a base material, so that the box body has higher tensile property, cracking and thermal runaway are prevented due to overall stress of the fabric, and after thermal runaway of a battery, due to the fact that resin has the porcelainized transformation capacity, when the battery burns, the thermal runaway of the battery is prevented; the resin can be converted into ceramic through porcelainization when meeting fire, the
