Abstract
A method of forming a radius filler may include providing an upper portion having substantially constant width composite plies, providing a base portion as a stack of variable width composite plies, and stacking the upper portion onto the base portion to form a radius filler stack.
Claims20
A method of forming a radius filler, comprising the steps of:
- providing an upper portion having substantially constant width composite plies;
- providing a base portion as a stack of variable width composite plies;
- and
- stacking the upper portion onto the base portion to form a radius filler stack.

A method of forming a radius filler, comprising the steps of:
- providing an upper portion having substantially constant width pre-preg composite plies;
- providing a base portion as a stack of variable width composite plies;
- stacking the upper portion onto the base portion to form a radius filler stack;
- and
- applying heat and pressure to the radius filler stack to form a final radius filler having a variable cross-sectional shape.

A method of forming a radius filler, comprising the steps of:
- forming a tip portion with a generally triangular cross-sectional shape;
- forming a keyway portion as a stack of substantially constant width composite plies;
- stacking the tip portion on the keyway portion to form an upper portion;
- providing a base portion as a stack of variable width composite plies;
- stacking the upper portion onto the base portion to form a radius filler stack;
- applying heat and pressure to the radius filler stack to form a final radius filler having a variable cross-sectional shape;
- and
- contouring opposing radius filler sides complementary to opposing radii of a radius filler region of a composite structure.
