The invention relates to the field of automobile engine hoods, in particular to a metal-resin composite automobile front engine hood and a preparation method of the metal-resin composite automobile front engine hood. An upper peripheral reinforcing rib, a right peripheral reinforcing rib, a lower peripheral reinforcing rib and a left peripheral reinforcing rib are fixedly arranged on the inner edge of the continuous carbon fiber composite material outer plate, and a traditional metal outer plate and inner plate structure is abandoned and replaced by a resin matrix composite material outer plate and a metal inner reinforcing rib. The outer plate is made of continuous fiber thermoplastic composite materials, the inner reinforcing ribs are made of metal materials, and the outer plate and the inner reinforcing ribs are formed at a time in a non-mechanical connection mode. The preparation method solves the problems of high material price, complex process degree and the like. 本发明涉及汽车引擎盖领域，尤其是一种金属树脂复合体汽车前引擎盖及其制备方法，包
