Abstract
A washer comprises a ring and a composite structure attached to the ring. The composite structure has a slotted shape and a hole that is centrally located with respect to an axis passing through the ring.
Claims20
A method for manufacturing a washer, the method comprising:
- folding a plurality of composite layers of thermally insulating material over a ring to form a peripheral edge of folded composite layers for the washer, the peripheral edge having slots, the folded composite layers further defining a hole in the washer, and the peripheral edge being raised with respect to an inner portion of the folded composite layers.
A method for forming a washer comprising:
- folding a first patterned composite layer of thermally insulating material over a ring;
- and
- folding a second patterned composite layer of thermally insulating material over the first patterned composite layer at an angular orientation with respect to the first patterned composite layer, wherein folded composite layers are formed, wherein the folded composite layers define a hole in the washer and also define a peripheral edge, and wherein folding the second patterned composite layer includes forming slots in the peripheral edge, and wherein the slots are defined by an orientation of a first pattern of the first patterned composite layer relative to a second pattern of the second patterned composite layer.
A method for manufacturing a washer, the method comprising:
- creating a stack of plurality of composite layers of thermally insulating material;
- positioning a ring relative to the stack;
- and
- folding the plurality of composite layers of thermally insulating material over and onto a ring to form a peripheral edge of folded composite layers for the washer, the peripheral edge having slots, the folded composite layers further defining a hole in the washer, and the peripheral edge being raised with respect to an inner portion of the folded composite layers.
