Adhesive bonded attachment assembly for an insulation blanket
First Claim
1. An adhesive bonded attachment assembly for supporting an insulation blanket on one side of a substrate, said attachment assembly comprising:
- an attachment member including an enlarged base defining a mounting surface having an extended surface area for adhesive bonded attachment to the one side of the substrate, and a fastener element; and
a cap fastener including a radially enlarged and thermally insulated cap member, and a fastener component for assembly with said fastener element of said attachment member;
at least one of said fastener element and said fastener component having a size and shape to extend at least partially into a mounting port formed in the insulation blanket, and said radially enlarged cap member having a size and shape to overlie said fastener element and further to overlie and engage the insulation blanket in a region surrounding said mounting port;
said insulated cap member comprising an inboard-side cap plate and an outboard-side cap plate cooperatively defining an internal cap chamber having an insulation material carried therein.

Abstract
An adhesive bonded attachment assembly is provided for supporting and retaining an insulation blanket on a substrate such as aircraft engine nacelle or the like. The attachment assembly includes a stud attachment having a base for adhesive bonded affixation to the nacelle substrate and a fastener element such as a threaded stud extending from the base at least partially into a grommet-lined mounting port formed in the insulation blanket. A radially enlarged, insulated cap fastener is secured to the fastener element to retain the insulation blanket on the nacelle substrate in a manner shielding surrounding structures and components from heat generated during engine operation. The insulated cap fastener projects radially beyond the associated grommet for improved heat-shielding of the adhesive bonded stud attachment, thereby safeguarding against debonding of the attachment base in response to high temperature exposure.

10. An adhesive bonded attachment assembly in combination with an insulation blanket having a mounting port formed therein and a substrate having a relatively high temperature environment at one side thereof, said attachment assembly supporting said insulation blanket on said one side of a said substrate at a position between said substrate and the high temperature environment, said attachment assembly comprising:
-
an attachment member including an enlarged base defining a mounting surface having an extended surface area for adhesive bonded attachment to said one side of the substrate, and a fastener element carried by said base; a bonding agent adhesively bonding said mounting surface of said enlarged base onto said one side of said substrate; and a cap fastener including a radially enlarged and thermally insulated cap member, and a fastener component carried by said cap member for assembly with said fastener element of said attachment member; at least one of said fastener element and said fastener component having a size and shape to extend at least partially into said mounting port formed in said insulation blanket, and said radially enlarged cap member having a size and shape to overlie said fastener element and further to overlie and engage said insulation blanket in a region surrounding said mounting port; said insulated cap member comprising an inboard-side cap plate and an outboard-side cap plate cooperatively defining an internal cap chamber having an insulation material carried therein. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
