Abstract

A thrust reverser for a nacelle may comprise a composite track beam and a composite lug. The composite lug may be inserted through a through-hole in the composite track beam. Continuous fibers in the composite lug may provide strength in the in-plane direction.

First claim

We claim:

1. A composite lug for a track beam comprising:
a support extending from a first end to a second end in a lateral direction, the support defining a planar surface;
a first flange coupled to and substantially perpendicular to the planar surface of the support, the first flange defining a first aperture disposed therethrough;
a second flange coupled to and substantially perpendicular to the planar surface of the support, the second flange defining a second aperture disposed therethrough, the second flange disposed between the first flange and the second end of the support, the first flange disposed between the first end of the support and the second flange;
a first continuous fiber extending along the first flange, the support, and the second flange,
a second continuous fiber extending from the first end of the support to a distal end of the first flange; and
a third continuous fiber extending from the second end of the support to a distal end of the second flange, wherein:
the first flange and the second flange are configured to be inserted through a corresponding first aperture and a corresponding second aperture of a track beam, and
the planar surface is configured to fuse with a mating surface of the track beam.

2. The composite lug of claim 1 , wherein the composite lug comprises a thermoplastic material.

3. The composite lug of claim 1 , wherein the composite lug comprises a Pi-shape.

4. The composite lug of claim 3 , further comprising a fourth continuous fiber extending from the first end of the support to the second end of the support, wherein the fourth continuous fiber is not located within the first flange or the second flange.

5. The composite lug of claim 1 , wherein a first plane defined by the first flange is substantially parallel to a second plane defined by the second flange.

6. The composite lug of claim 1 , wherein a first length of the first flange is substantially equal to a second length of the second flange.
