In the embodiment of the present invention, unlike the conventional nacelle cover, which usually uses glass fiber reinforced plastics or carbon steel, the planar module 201 and the cambered surface module 202 may be composite plates, which realizes the development of the nacelle cover material. The composite material plate is 6-10mm in thickness and comprises an aluminum and stainless steel metal composite plate, a bamboo-wood fiber integrated plate, an aluminum honeycomb composite plate and an aluminum alloy panel. The composite material plates 201 arranged on the two side planes of the nacelle cover may be the aluminum and stainless steel metal composite plates and the bamboo-wood fiber integrated plates. The composite material plate arranged at the top of the cabin cover can be matched with a rib plate due to the need of considering the bearing requirements of standing personnel and the like, and is reinforced by bonding the rib plate in the middle, namely the aluminum and stainless steel metal composite plate and the bamboo-wood fiber integrated plate; or may be a more rigid aluminum honeycomb composite panel (AACS). The composite material plate arranged at the bottom of the cabin cover can be the aluminum and stainless steel metal composite plate or an aluminum alloy panel which is matched with a framework for reinforcement.

By adopting the composite board, the existing composite board can be directly spliced without inputting a new mould, so that huge mould cost of engine room covers of different models and sizes is avoided. In addition, the traditional upper cabin cover die has lower input and production efficiency, and the composite material plate can be used for production line production such as PE extrusion, leveling forming, pre-sticking of a polymer film, conveying and composite forming, so that the production efficiency is effectively improved.

In addition, the edges of the plane module and the cambered surface module adopting the composite material plate can be provided with bends, wherein the lengths of the bends can be adjusted based on the width size of the composite material plate. Reinforcing ribs can also be bonded or welded in the weakened areas by a simple auxiliary process to achieve local reinforcement of the composite material plates or reinforcement of the bends.
