Abstract
A fiber cushion body comprises a first portion in which fibers have a preferential orientation along a first direction and at least a second portion having a fiber orientation and/or density different from the first portion. The fiber cushion body is processed using laser radiation to form a laser cut or laser weld.
Claims16
A method of processing a fiber cushion body formed from thermally cross-linked fibers, the method comprising:
- applying laser radiation to the fiber cushion body to form at least a laser cut or a laser weld in the fiber cushion body, wherein the fiber cushion body to which the laser radiation is applied includes a first portion in which fibers have a preferential orientation along a first direction and a second portion having a fiber orientation and/or density different from the first portion.
A fiber cushion body comprising:
- a first portion in which fibers have a preferential orientation along a first direction;
- and
- a second portion having a fiber orientation and/or density different from the first portion,
- wherein the first portion and the second portion are integrally formed,
- wherein a laser cut and/or a laser weld is formed on at least one surface of the fiber cushion body,
- wherein a majority of the fibers of the first portion is oriented at an angle of less than 45° to a direction which is perpendicular to a major face of the fiber cushion body, and
- wherein the fiber cushion body is formed from thermally cross-linked fiber material.
