Abstract: A method of manufacturing a door skin and a fuselage wall having a doorway and a member extending into the doorway for abutting the door includes placing a first sheet of uncured composite material on a mold plate to define the door and fuselage skin, disposing an insert over the first sheet overlapping a desired periphery of the door, placing a second sheet of uncured composite material on a peripheral portion of the insert and over the first sheet adjacent the peripheral portion of the insert to form the member, curing the sheets and bonding the sheets together adjacent the insert during the cure, removing the insert from between the sheets after cure, and separating the door skin from the wall skin after cure by moving a cutting tool through the first sheet and without penetrating the second sheet around the desired periphery of the door. An assembly for manufacturing the door skin and a fuselage wall is also discussed.

Abstract: A caul body for forming a composite structure comprises a laminate having at least one carbon layer and at least one silicone layer. The at least one silicone layer defines an outer surface of the laminate. The laminate has a first region and a second region. A thickness of the at least one carbon layer in the first region is greater than a thickness of the at least one carbon layer in the second region. The first region has a hardness value greater than a hardness value of the second region.

Abstract: A method of manufacturing a self-supporting, monolithic fuselage body, including engaging peripheral mandrel sections around at least one central mandrel section, placing uncured composite material on the mold surface, curing the composite material on the mold surface, and sliding the central mandrel section(s) out of engagement with the peripheral mandrel sections and disengaging the peripheral mandrel sections from the cured composite material without collapsing the mandrel sections. The peripheral mandrel sections each include a shape-retaining core of a thermally insulating material and an outer layer on an outer surface of the shape-retaining core. The outer layer has a coefficient of thermal expansion within the range of variation of that of the coefficient of thermal expansion of the composite material. A mandrel for layup and cure of a predetermined composite material in the manufacture of a monolithic fuselage is also discussed.

Abstract: Embodiments refer generally to systems and methods for manufacturing a cylindrical spar tube of the sort that might be used in a horizontal stabilizer for a helicopter. An exemplary method may comprise laying out onto a flat surface (and possibly stacking) plies of composite material, rolling the material onto a mandrel while applying pressure and curing the rolled material.

Abstract: A method of manufacturing a monolithic component having internal wall(s), including separately placing uncured composite material on a mold parts, placing the mold parts on a support plate with a portion of the uncured composite material extending between and in contact with the adjacent mold parts, interconnecting the adjacent mold parts through a connection allowing limited relative movement on the support plate along a direction corresponding to a thickness of the uncured composite material therebetween, biasing the adjacent mold part toward each other along the limited relative movement to provide a compressive force on the uncured composite material extending therebetween, and curing the composite material to obtain the monolithic component with each internal wall being formed between adjacent mold parts. The bias causes the adjacent mold parts to move toward each other as the thickness of uncured material extending therebetween reduces during curing. A tool assembly is also discussed.
