Abstract: Examples are disclosed herein that relate to vehicles, composite parts, and methods for forming a composite part for a vehicle. In one example, a vehicle comprises a composite part comprising a skin comprising one or more material layers. The composite part further comprises a stiffener comprising one or more material layers, wherein the stiffener comprises a flange and a web. The composite part also includes an additively manufactured sub-structure positioned between at least a portion of the skin and at least a portion of the stiffener. The additively manufactured sub-structure comprises at least one flange portion, at least one radius, and at least one radius filler. A polymer matrix is co-infused within the skin, the stiffener, and the additively manufactured sub-structure.

Abstract: Disclosed herein are methods for fabricating a composite structure by forming, via additive manufacturing, a solid-phase component; positioning the solid-phase component and a reinforcement into a mold cavity; and consolidating, in the mold cavity, the solid-phase component, the reinforcement, and a liquid-phase component to form the composite structure.

Abstract: The invention relates to a coating system, in particular a coating system containing an organometallic layer which allows the selective removal of post coating layers from substrates without detrimental impact to their “in-service” performance. The organometallic layer comprises (a) an organic polymer containing multi-chelating functionalities; and (b) a metallic agent which forms an organo metallic complex with the organic polymer containing multi-chelating functionalities and is located between an optionally coated substrate and at least one post coating layer of a coating system.

Abstract: The present invention generally relates to self healing polymer materials comprising thermoset and thermoplastic polymers. The present invention also relates to a method of manufacturing self healing polymer materials, methods of post-curing and healing the self healing polymer materials, composite materials comprising self healing polymer materials and methods of preparing the composite materials. In an attempt to develop improved structural materials, polymers and polymer materials have been identified that can be used in materials to act as self healing agents to repair structural damage occurring in the materials. The self healing polymer materials that have been identified are capable of being healed under post-curing or healing conditions.
