3D weaving material and method of 3D weaving for sporting implements
Methods for fabricating a 3D woven material and exemplary 3D woven material for sporting implements are disclosed. The exemplary weaves can be incorporated into any sporting implements, such as, baseball bats, lacrosse sticks, hockey sticks, rackets, helmets, and other protective equipment. The example sporting implement can be constructed, partially or entirely, with a woven or braided three dimensional structure. The 3D woven material can be a multi-directional layup having tows oriented in three directions (X, Y and Z) and also at any angle created by the combination of two or three directions. A single woven preform can be formed that can have a near net shape of the formed product, with the fibers oriented in a way that will be optimal for the particular application.
1. A sporting implement having a 3D woven material comprising:
a first plurality of tapes extending in a warp direction;
a second plurality of tapes extending in a weft direction;
a third plurality of tapes extending in the Z direction;
wherein the first plurality of tapes forms four intersections with the second plurality of tapes,
wherein the first plurality of tapes alternatingly extend at a first angle and a second angle relative to the z-axis and the second plurality of tapes alternatingly extend at a first angle and a second angle relative to the z-axis;
the sporting implement comprising a shaft having a first end and second end, wherein both the first end and second end of the shaft include the 3D woven material.
2. The sporting implement of claim 1 wherein the first angle that the first plurality of tapes alternatingly extends is greater than 20° from the z-axis and the second angle is less than −20° from the z-axis.
3. The sporting implement of claim 1 wherein the first angle that the second plurality of tapes alternatingly extends is greater than 20° from the z-axis and the second angle is less than −20° from the z-axis.
4. The sporting implement of claim 1 wherein the first angle that the first plurality of tapes alternatingly extends is 45° from the z-axis and the second angle is −45° from the z-axis.
5. The sporting implement of claim 1 wherein the first angle that the second plurality of tapes alternatingly extends is 45° from the z-axis and the second angle is −45° from the z-axis.
