Abstract
A composite part is provided and includes a component, a first set of first composite plies with finite lengths and a second set of second composite plies with finite lengths. A respective end of each of the first composite plies is wrapped around the component in a clockwise wrapping direction and includes first fibers. A respective end of each of the second composite plies is wrapped around the component in a counter-clockwise wrapping direction and includes second fibers.
Claims5
A method of assembling a composite part, the method comprising:
- arranging first and second composite plies of finite lengths respectively comprising first and second fibers at first and second sides of an axis, respectively;
- disposing a component on the axis;
- wrapping an end of a first composite ply, which is closest to the first side of the axis, around the component in a counter-clockwise wrapping direction;
- wrapping an end of a first second composite ply, which is closest to the second side of the axis, around the component in a clockwise wrapping direction;
- wrapping an end of a next first composite ply, which is next closest to the first side of the axis, around the component in the counter-clockwise wrapping direction;
- and
- wrapping an end of a next second composite ply, which is next closest to the second side of the axis, around the component in the clockwise wrapping direction,
- wherein the arranging comprises disposing a first tube coaxially inside a second tube, cutting axial cuts into opposite sides of the first tube to form the first composite ply and the first second composite ply and cutting axial cuts into opposite sides of the second tube to form the next first composite ply and the next second composite ply, and wherein the first and second tubes are multi-ply tubes.

A composite part assembly method, comprising:
- arranging first and second composite plies respectively comprising first and second fibers at first and second sides of an axis, respectively;
- disposing, on the axis, a component comprising a bushing and an apex portion with a peak point;
- wrapping respective ends of first and second composite plies, which are closest to the first and second sides of the axis, respectively, around the bushing and the apex portion in counter-clockwise and clockwise directions, respectively;
- wrapping respective ends of next first and next second composite plies, which are next closest to the first and second sides of the axis, respectively, around the bushing and the apex portion in the counter-clockwise and clockwise directions;
- wherein the arranging comprises disposing a first tube coaxially inside a second tube, cutting axial cuts into opposite sides of the first tube to form the first composite ply and the first second composite ply and cutting axial cuts into opposite sides of the second tube to form the next first composite ply and the next second composite ply, and wherein the first and second tubes are multi-ply tubes.
