Abstract
A method of fabricating a conformal deltoid noodle includes providing a composite prepreg material having a predetermined length and a width, the predetermined length being aligned along a longitudinal axis; subjecting the composite prepreg material to a cutting process to form a notched section coextensive along the predetermined length; and rolling the composite prepreg material along its width to create the conformal deltoid noodle.

A method of fabricating a conformal deltoid noodle, comprising:
- providing a composite prepreg material having a length and a width, the length being aligned along a longitudinal axis;
- subjecting the composite prepreg material to a cutting process to form a notched section along the length;
- and
- rolling the composite prepreg material along its width to create the conformal deltoid noodle;
- wherein the notched section resides substantially at the center of the deltoid noodle.
A method of fabricating a conformal deltoid noodle, comprising:
- providing a composite prepreg material having a length and a width, the length being aligned along a longitudinal axis;
- subjecting the composite prepreg material to a cutting process to form a notched section along the length;
- and
- rolling the composite prepreg material along its width to create the conformal deltoid noodle;
- wherein the composite prepreg material comprises unidirectional fibers aligned along the longitudinal axis.
A method of fabricating a conformal deltoid noodle, comprising:
- providing a composite prepreg material having a length and a width, the length being aligned along a longitudinal axis;
- subjecting the composite prepreg material to a cutting process to form a notched section along the length;
- and
- rolling the composite prepreg material along its width to create the conformal deltoid noodle;

A method of fabricating a composite component having reinforcement fibers, comprising
- providing a platform having a length extending in a direction parallel to a plane;
- providing a body including a first portion which extends in a first direction and a second portion which extends in a direction lateral to the first direction;
- engaging the platform with the first portion to define a deltoid cavity;
- forming a deltoid noodle comprising chopped fibers and unidirectional fibers;
- inserting the deltoid noodle in the deltoid cavity;
- and
- performing a curing process to bond the platform and the body to the deltoid noodle, thereby to form the composite component;
- wherein the forming of the deltoid noodle further comprises:
- providing a composite prepreg material having a second length and a width, the second length being aligned along a longitudinal axis;
- subjecting the composite prepreg material to a cutting process to form a notched section along the second length;
- and
- rolling the composite prepreg material along its width to create the deltoid noodle.
