Composite structures and methods of forming composite structures

A composite structure, comprising:

• a first component, wherein the first component includes a panel incorporating a plurality of sheets of fiber reinforced thermoplastic material;
• a second component, wherein the second component includes a panel incorporating a plurality of sheets of fiber reinforced thermoplastic material;
• a first composite insert, wherein the first composite insert includes a plurality of reinforcing fibers and a thermoplastic material, and wherein at least a portion of the first composite insert is located within a first portion of an interior volume located between an interior surface of the first component and an interior surface of the second component;
• and
• a second composite insert, wherein the second composite insert includes a plurality of reinforcing fibers and a thermoplastic material, wherein at least a portion of the second composite insert is located within a second portion of the interior volume located between the interior surface of the first component and the interior surface of the second component, wherein the first and second components are fused to one another along at least a first joint portion, wherein the first composite insert is fused to at least one of the first and second components, and wherein the second composite insert is fused to at least one of the first and second components.
