Abstract
Official abstract text for this publication.
An annular bushing includes an annular cylindrical portion with a flange that defines a fastener aperture along an axis. A multiple of spacers extend from an outer surface of the annular cylindrical portion and the flange. The multiple of spacers are operable to control a bond line thickness.
First claim
Opening claim text (preview).
What is claimed is: 1 . An annular bushing, comprising: an annular cylindrical portion with a flange that defines a fastener aperture along an axis; and a multiple of spacers that extend from an outer surface of the annular cylindrical portion and the flange, the multiple of spacers operable to control a bond line thickness. 2 . The annular bushing as recited in claim 1 , wherein the multiple of spacers includes a multiple of ribs generally parallel to the axis. 3 . The annular bushing as recited in claim 1 , wherein the multiple of spacers include a helical rib. 4 . The annular bushing as recited in claim 1 , wherein the flange defines an angle of about 100 degrees. 5 . The annular bushing as recited in claim 1 , wherein the fastener aperture is countersunk. 6 . The annular bushing as recited in claim 1 , wherein the annular cylindrical portion and the flange are manufactured from a polyimide material. 7 . The annular bushing as recited in claim 1 , wherein the annular cylindrical portion and the flange are manufactured from a polyetherimide material. 8 . A laminated composite assembly, comprising: a first laminated composite component; a second component; an annular bushing bonded to the first laminated composite component; and a fastener through the annular bushing to at least partially retains the first laminated composite component to the second component. 9 . The assembly as recited in claim 8 , wherein the annular bushing is manufactured from a polyimide material. 10 . The assembly as recited in claim 8 , wherein the annular bushing is manufactured from a polyetherimide material. 11 . The assembly as recited in claim 8 , wherein the annular bushing is countersunk within the first composite laminate component. 12 . The assembly as recited in claim 8 , wherein the fastener is countersunk within the annular bushing. 13 . The assembly as recited in claim 8 , wherein the annular bushing is countersunk within the first laminated composite component and the fastener is countersunk within the annular bushing. 14 . The assembly as recited in claim 8 , wherein the fastener is a rivet. 15 . The assembly as recited in claim 8 , wherein the first laminated component is a gas turbine engine nacelle component. 16 . The assembly as recited in claim 8 , wherein the first laminated component is a skin of a gas turbine engine nacelle. 17 . A method of replacing an aperture in a laminated component, the method comprising: machining an aperture in place of a deformed aperture; and bonding an annular bushing into the aperture, the annular bushing including a multiple of spacers to control a bond line thickness between the annular bushing and the aperture. 18 . The method as recited in claim 17 , further comprising retaining the annular bushing within the countersunk aperture with a hole clamp during the bonding. 19 . The method as recited in claim 17 , further comprising countersinking the aperture.
