Composite components and methods for forming composite components are provided. For example, a composite component of a gas turbine engine comprises a composite material, a plurality of piezoelectric fibers, and an anti-icing mechanism. The anti-icing mechanism is in operative communication with the piezoelectric fibers such that the anti-icing mechanism is activated by one or more electrical signals from the piezoelectric fibers. In exemplary embodiments, the composite component is a composite airfoil and the anti-icing mechanism is one or more heating elements. Methods for forming composite components may comprise forming piezoelectric plies comprising piezoelectric fibers embedded in a matrix material; forming reinforcing plies comprising reinforcing fibers embedded in the matrix material; laying up the piezoelectric and reinforcing plies to form a ply layup; and processing the ply layup to form the composite component. Methods including forming a piece of piezoelectric material that is adhered to a composite component also are provided.

An ergonomic frame-filler placement tool is manually operable to supply a vacuum fluid flow at a distal end of the tool that can be used by a worker to pick up and hold a piece of frame-filler material to the distal end of the tool, which enables the worker to manipulate the tool to position the piece of frame-filler material over a desired location of a fuselage mandrel and then manually stop the vacuum fluid flow at the distal end of the tool to position the piece of frame-filler material at the desired location on the mandrel.

Systems and methods of forming fiber reinforced polymer (FRP) composites with electrostatic dissipative properties are described herein. The FRP composite is bonded to a surface and integrates a grounding system to dissipate electro-static energy, thus eliminating the potential risk of explosion. The system can be used for structures that require reinforcement and that are susceptible to electro-static explosions.

A method of forming a polyolefin-perovskite nanomaterial composite which contains oriented electrically and thermally conductive pathways. The method involves milling a polyolefin with particles of a perovskite nanomaterial, molding to forma composite plate, and subjecting the composite plate to an AC voltage. The AC voltage forms oriented electrically and thermally conductive pathways by partial dielectric breakdown of the composite. The presence of the oriented electrically and thermally conductive pathways gives the polyolefin-perovskite nanomaterial electrical and thermal conductivity and dielectric permittivity higher than the polyolefin alone.

A joint structure includes a first member having a fit-in groove, a second member made of a material different from a material of the first member and having an insertion section to be inserted into the fit-in groove, and a plurality of bonding layers having different hardness and formed between the fit-in groove and the insertion section.
