Problems solved by technology

Forming composite splice joints between longer composite sections may be impractical, however, as commercial autoclaves may not be large enough to accommodate relatively long length parts such as wing stringers, spars, and frames

Embodiment Construction

[0050] figure 1 A general production unit 208 is shown that may be used to join elongate composite segments such as composite segments 104a, 104b, 104c to form a continuous structural member 104 such as, but not limited to, a stringer, spar, or frame. At least the first composite section 104 ( a ) and the second composite section 104 ( b ) are joined in end-to-end relationship using a structural bond forming a splice joint 110 . Composite sections 104 - 104c may be supported by a plurality of alignment bonded assembly fixtures 184 . Bonding assembly fixture 184 supports the aligned composite sections 104a-104c while allowing the latter to be drawn along their longitudinal axis 265 into bonding machine 186 at bonding stations 210, 212, respectively. Bonding stations 210 , 212 are positioned along the length of structural member 104 at locations where splice joint 110 is to be bonded.

Abstract

A composite structural member includes first and second composite sections spliced together by an overlapping composite splice member.

Description

technical field [0001] The present disclosure relates generally to composite structures, and more particularly to methods and apparatus for joining composite sections using bonded splices and composite structural members made therefrom. Background technique [0002] To make relatively long composite structural members, splices are sometimes used to join composite sections together. In aircraft manufacturing, for example, relatively long wing stringers, spars, frames, and other complex composite geometries can be formed by joining two or more longer composite segments using metal splice members and fasteners . However, metal splice members are not ideal for a number of assembly reasons. [0003] Composite splice members can be used to join composite structural members. But because commercial autoclaves may not be large enough to accommodate relatively long parts such as wing stringers, spars, and frames, forming composite splice joints between longer composite sections may...
