Assignee:

The Boeing Company - Chicago IL

International Classification:

B32B 27/00
B64C 3/20

US Classification:

156242, 156229, 156299, 1563069, 24412313

Abstract:

A stabilizing mechanism for resisting relative movement of upper and lower laminates of a composite structure having a core comprises a lower grip strip and at least one upper grip strip. The lower grip strip may be mounted to a tool upon which the composite structure may be processed. The lower grip strip may include an outer surface having at least one engagement feature for engaging at least one of the upper and lower laminates which make up the composite structure. The upper grip strip may have opposing outer surfaces which may include at least one engagement feature for engaging the lower strip and at least one of the upper and lower laminates.

Abstract:

A method of manufacturing curved composite structural elements can include fabricating a web ply in a flat curve over a removable substrate and laying up the ply on a curved web surface of a manufacturing tool. The method also can include laying up a diagonal ply with fibers oriented at +/−45 from the centerline of the web surface. The method further can include cutting a unidirectional composite tape into segments and laying up the tape segments to form a cross ply with a fiber orientation normal to the centerline of the web surface. One or both edges of the diagonal and cross plies may be folded over one or two sides of the manufacturing tool to form one or two flange surfaces. Additionally, a cap ply can be laid up on one or both flange surfaces using composite tape. The structural element layup can then be inspected and any excess composite material can be trimmed away.
