## Abstract

A heat protective device includes a sheet having a first edge opposite a second edge. The sheet is comprised of a plurality of intertwined links that are movable with respect to each other. A strip is positioned between the first edge of the sheet and the second edge of the sheet. A fastener couples the first edge of the sheet and the second edge of the sheet to the strip to form a tubular shape. The fastener is configured to adjust a diameter of the tubular shape to releasably fix the heat protective device about an object. A method for manufacturing a heat protective device is also disclosed.

## Claims

### Claim 1

A heat protective device comprising:
a sheet having a first edge opposite a second edge, and comprised of a plurality of intertwined links that are movable with respect to each other;
a strip positioned between the first edge of the sheet and the second edge of the sheet; and
a fastener coupling the first edge of the sheet and the second edge of the sheet to the strip to form a tubular shape, the fastener being configured to adjust a diameter of the tubular shape to releasably fix the heat protective device about an object.

### Claim 2 (depends on 1)

The heat protective device of claim 1 wherein the sheet is comprised of a ceramic material selected from silicon carbide (SiC), zirconia (ZrO2), alumina, porcelain, aluminum titanate, silicate, or other ceramic material.

### Claim 3 (depends on 1)

The heat protective device of claim 1 wherein each link in the plurality of intertwined links has a three-dimensional, rectangular U-shape and a circular cross-section.

### Claim 4 (depends on 1)

The heat protective device of claim 1 wherein:
the sheet further comprises a third edge opposite a fourth edge; and
the fastener couples the third edge of the sheet and the fourth edge of the sheet to the strip, and the fastener is configured to releasably fix the heat protective device about the object.

### Claim 5 (depends on 4)

The heat protective device of claim 4 wherein the plurality of intertwined links at the first edge, the second edge, the third edge and the fourth edge of the sheet further comprise a loop, the loop configured to receive the fastener.

### Claim 6 (depends on 1)

The heat protective device of claim 1 wherein the strip is a continuous material comprised of a heat-resistant textile selected from meta-aramid polymers, composite textiles, ceramic-coated textiles, ceramic fiber textiles, or a solid sheet of heat-resistant material.

### Claim 7 (depends on 1)

The heat protective device of claim 1 wherein the strip has an arc length along the object, and the arc length is based on an average radius of the object.

### Claim 8 (depends on 7)

The heat protective device of claim 7 wherein the object has the average radius less than or equal to 12.7 mm, and the arc length of the strip is two times the average radius of the object.

### Claim 9 (depends on 7)

The heat protective device of claim 7 wherein the object has the average radius ranging from greater than 12.7 mm to less than 38.1 mm, and the arc length of the strip is 1.5 to 2 times the average radius of the object.

### Claim 10 (depends on 7)

The heat protective device of claim 7 wherein the average radius ranges from greater than or equal to 38.1 mm, and the arc length of the strip is 1.0 to 1.5 times the average radius of the object.

### Claim 11 (depends on 1)

The heat protective device of claim 1 wherein the fastener is a flexible linear component selected from a thread, wire, strap, cord, ribbon, lace, tie, or other method.

### Claim 12

A method for manufacturing a heat protective device comprising:
printing, by a 3D printer, a sheet having a first edge and a second edge, and the sheet being comprised of a plurality of intertwined links that are movable with respect to each other;
providing a jig having a base with a top surface, and a plurality of protrusions coupled to the top surface and extending above the top surface, each protrusion of the plurality of protrusions being spaced apart from one another;
placing the sheet on the top surface of the jig, the plurality of intertwined links of the sheet positioned between the plurality of protrusions of the jig;
applying heat to the sheet and the jig; and
removing the sheet from the jig to form the heat protective device;
wherein the sheet and the jig are comprised of the same material, and the jig is configured with dimensions to volumetrically shrink at the same rate as the sheet during the heating.

### Claim 13 (depends on 12)

The method of claim 12 wherein the jig is 3D printed.

### Claim 14 (depends on 12)

The method of claim 12 wherein the sheet and the jig are comprised of a ceramic material selected from silicon carbide (SiC), zirconia (ZrO2), alumina, porcelain, aluminum titanate, silicate, or other ceramic material.

### Claim 15 (depends on 12)

The method of claim 12 wherein each link in the plurality of intertwined links has a three-dimensional, rectangular U-shape and a circular cross-section.

### Claim 16 (depends on 12)

The method of claim 12 wherein the base of the jig has a thickness that is 1.0 to 2.5 times an average diameter of a link of the plurality of intertwined links.

### Claim 17 (depends on 12)

The method of claim 12 wherein each protrusion of the plurality of protrusions is T-shaped, and spaced apart from another protrusion according to a width of a link of the plurality of intertwined links.

### Claim 18 (depends on 12)

The method of claim 12 wherein each protrusion of the plurality of protrusions has a wall thickness of 0.25 to 1 time an average diameter of a link of the plurality of intertwined links.

### Claim 19 (depends on 12)

The method of claim 12 further comprises:
positioning a strip between the first edge of the sheet and the second edge of the sheet;
coupling a fastener to the first edge of the sheet and the second edge of the sheet to the strip to form a tubular shape, the fastener configured to adjust a diameter of the tubular shape to releasably fix the heat protective device about an object.

### Claim 20 (depends on 19)

The method of claim 19 wherein:
the strip is a continuous material comprised of a heat-resistant textile selected from meta-aramid polymers, composite textiles, ceramic-coated textiles, ceramic fiber textiles, or a solid sheet of heat-resistant material;
