STACKED NOODLE FOR HIGH CAPACITY PULL-OFF FOR A COMPOSITE STRINGER

摘要

An apparatus comprises a composite elongate member having a side configured for attachment to a surface of a structure; a channel on the side extending along a length of the composite elongate member; and a number of composite structures configured for placement in the channel and configured to attach a portion of the side of the composite elongate member to the structure, wherein a composite structure in the number of composite structures comprises layers having different orientations selected to increase a capacity of the composite elongate member to withstand forces that pull the composite elongate member away from the structure, wherein the composite structure comprises groups of the layers that are laid up to form the composite structure and wherein a group in the groups of the layers comprises at least two layers, and wherein a layer in the group in the groups of the layers comprises fibers arranged at an angle selected from one of a first angle of about zero degrees with respect to an axis through the composite elongate member and a second angle between a range from about 45 degrees to about 50 degrees with respect to the axis through the composite elongate member.
