Abstract
A method of manufacturing a tubular member includes stacking a plurality of materials on a rolling table and rolling the plurality of materials around a mandrel to form the tubular member. The plurality of materials include one or more bottom layers and an upper layer stacked on top of the one or more bottom layers. The upper layer comprises a fibrous material including (a) a first plurality of fibers that extend in a positive direction relative to a lengthwise direction of the upper layer and (b) a second plurality of fibers that extend in a negative direction relative to the lengthwise direction of the upper layer. The first plurality of fibers and the second plurality of fibers form an X-pattern.

A method of manufacturing a tubular member, the method comprising:
- stacking a plurality of materials on a rolling table, the plurality of materials including one or more bottom layers and an upper layer stacked on top of the one or more bottom layers, the upper layer comprising a fibrous material including (a) a first plurality of fibers that extend in a positive direction relative to a lengthwise direction of the upper layer and (b) a second plurality of fibers that extend in a negative direction relative to the lengthwise direction of the upper layer, the first plurality of fibers and the second plurality of fibers forming an X-pattern;
- and
- rolling the plurality of materials around a mandrel to form the tubular member.
A tubular member comprising:
- a sidewall including with a plurality of layers comprising a plurality of differing materials, a first material of the plurality of differing materials including (a) a first plurality of fibers that extend helically through the sidewall along a length of the tubular member in a positive direction and (b) a second plurality of fibers that extend helically through the sidewall along the length of the tubular member in a negative direction.
A method of manufacturing a tubular member, the method comprising:
- providing a first sheet of a first material, the first sheet having a first shape, the first sheet having a first material property;
- providing a second sheet of a second material, the second sheet having a second shape different than the first shape, the second material having a second material property different than the first material property;
- providing a third sheet of a third material, the third sheet having a third shape different than the first shape and the second shape, the third material having a third material property different than the first material property and the second material property;
- stacking the first sheet, the second sheet, and the third sheet on a rolling table;
- and
- rolling the first sheet, the second sheet, and the third sheet around a mandrel to form the tubular member.
