Abstract
A method and apparatus for forming a radius filler. A lattice is formed of connecting elongate members having a three-dimensional shape of the radius filler. A resin is placed within the lattice.
Claims20
An apparatus that comprises:
- a lattice shaped as a one-piece additive manufactured structure that comprises unified elongate members that form a first curved peripheral side, a second curved peripheral side, and a third peripheral side, wherein:
- a first elongate member of the unified elongate members extends from the first curved peripheral side to the second curved peripheral side:
- and
- a second elongate member of the unified elongate members extends from the first curved peripheral side to the third peripheral side;
- and
- a resin that fills all space between the unified elongate members in the lattice and forms a radius filler.

A radius filler that comprises:
- a lattice shaped as a one-piece additive manufactured structure that comprises a sintered metal powder configured to form unified elongate members that comprise:
- a first curved peripheral side, a second curved peripheral side, and a third peripheral side, configured to fill a channel in a composite part, wherein:
- a first elongate member of the unified elongate members extends from the first curved peripheral side to the second curved peripheral side;
- and
- a second elongate member of the unified elongate members extends from the first curved peripheral side to the third peripheral side;
- and
- a resin that fills any space between the unified elongate members, wherein the lattice and the resin comprise a number of desired performance parameters that comprise a stiffness.

A lattice shaped as a single additive manufactured structure configured to fill a void formed between walls of connected parts, such that the lattice comprises:
- unified elongate members that form a first curved peripheral side, a second curved peripheral side, and a third peripheral side, of the lattice, wherein:
- a first elongate member of the unified elongate members extends from the first curved peripheral side to the second curved peripheral side;
- and
- a second elongate member of the unified elongate members extends from the first curved peripheral side to the third peripheral side;
- the lattice conforms to a shape of the void and is configured to touch every wall of the void such that loads applied to the lattice distribute along an x-axis, a y-axis, and a z-axis;
- and
- an interior infused with a resin that fills any space between the unified elongate members.
