Zusammenfassung: | The invention provides a front edge skin forming method and a front edge skin, relates to the technical field of composite materials, and solves the technical problems of dispersion, poor glue and the like caused by high laying difficulty, R-region resin accumulation, cracking of a honeycomb core in an R region, honeycomb marks on the surface of the skin and loss of a large amount of inner skin resin in the prior art. The method comprises the following steps of: laying prepreg on a male mold and curing to form an outer skin layer; laying a glue film carrier and a lightning protection copper net on the outer skin layer; transferring the outer skin out of the male mold; transferring the outer skin and the lightning protection copper net to a female mold; and laying an inner skin on the honeycomb core, and curing to form the leading edge skin. According to the method, the surface quality of the pneumatic surface and the glue joint surface of the outer skin is guaranteed at the same time, the problems of cracking |
