The embodiment of the invention discloses an engine hood, a manufacturing method of the engine hood and a vehicle, and belongs to the technical field of vehicles. The engine hood comprises an engine hood outer plate and an engine hood inner plate, and the engine hood inner plate is connected to the engine hood outer plate; the engine hood outer plate comprises a surface layer and an inner layer which are arranged in a stacked mode, the surface layer is the layer, away from the engine hood inner plate, of the engine hood outer plate, and the inner layer is the layer, close to the engine hood inner plate, of the engine hood outer plate. Wherein the surface layer is laid by adopting an SMC carbon fiber composite material, and the inner layer is laid by adopting a continuous carbon fiber composite material; the engine hood inner plate is laid by adopting SMC carbon fiber composite materials. On the premise of meeting performance indexes, the engine hood meets the strength and rigidity requirements of the engine hood, can achieve the purpose of reducing the weight, and has the advantages of being low in density, high in specific strength and high in specific modulus; and meanwhile, the attractiveness of the engine hood can be improved while weight reduction is achieved, and the user experience is improved.

    本申请实施例公开一种发动机罩、发动机罩的制造方法和车辆,属于车辆技术领域。发动机罩包括发动机罩外板和发动机罩内板,发动机罩内板连接于发动机罩外板;发动机罩外板包括层叠设置的表层和里层,表层为发动机罩外板远离发动机罩内板的一层,里层为发动机罩外板靠近发动机罩内板的一层;其中,表层采用SMC碳纤维复合材料铺设,里层采用连续性碳纤维复合材料铺设;发动机罩内板采用SMC碳纤维复合材料铺设。本申请的发动机罩在满足性能指标的前提下,既满足发动机罩的强度刚度要求,又能够实现减轻重量的目标,具有低密度、比强度高、比模量高的优势;同时,在实现减重的同时还能够提升发动机罩的美观性,提升用户体验。
