摘要： Radius fillers for composite structures, composite structures that include radius fillers, and systems and methods of forming the same are disclosed herein. The methods include determining a transverse cross-sectional shape of an elongate void space, which extends within a transition region that is defined by a plurality of plies of composite material, and determining a material property field of the transition region. The methods further include forming the radius filler by combining a plurality of lengths of composite tape to define a radius filler cross-sectional shape, which corresponds to the transverse cross-sectional shape of the elongate void space, and orienting a plurality of lengths of reinforcing fiber in each of the plurality of lengths of composite tape based, at least in part, on the material property field of the transition region. The radius fillers include radius fillers with selectively oriented reinforcing fibers. The composite structures include the radius fillers.

摘要： A radius filler for a composite assembly may include a pair of vertical ply stacks positioned in back-to-back relation. Each one of the vertical ply stacks may be formed of one or more thick plies of composite material formed in an L-shaped cross-section having a vertical leg and a lateral leg interconnected by a stack radius and defining a crescent region. At least one of the crescent regions may include one or more thin plies of composite material positioned adjacent to a stack radius inner surface. Each one of the thin plies may have a ply thickness that is less than the ply thickness of the thick plies.

摘要： Radius fillers for composite structures and composite structures that include radius fillers are disclosed herein. The radius fillers include a plurality of lengths of composite tape. Each of the plurality of lengths of composite tape includes a respective plurality of lengths of reinforcing fibers and a resin material. The plurality of lengths of reinforcing fibers in each of the plurality of lengths of composite tape defines a fiber axis direction. Each of the plurality of lengths of composite tape defines a respective fiber axis direction that is based, at least in part, on material properties of a transition region defined by a plurality of plies of composite material that defines an elongate void space within which the radius filler is configured to extend. The composite structures include the radius fillers.

摘要： A method of partially insulating an interior space of a pre-formed fluted core panel is disclosed herein. The fluted core panel includes a first facesheet, a second facesheet spaced apart from the first facesheet, and webs between the first facesheet and second facesheet. The interior space is defined between the first facesheet, the second facesheet, and adjacent webs. The method includes positioning a spacer in a first portion of the interior space, positioning a membrane between the spacer and a second portion of the interior space, and positioning insulation in the second portion of the interior space. Additionally, the method includes pressing the membrane against the spacer, curing the membrane, and removing the spacer from the first portion of the interior space.
