A yarn for reinforcing composite material includes carbon nanotubes. The yarn has also been treated to promote interaction with a resinous matrix.

A laminate structure may include: an aluminum layer; a glass composite layer adjacent to the aluminum layer; and/or a carbon composite layer adjacent to the glass composite layer, opposite to the aluminum layer. The glass composite layer may include one or more glass-fiber-reinforced thermoplastic prepreg plies. The carbon composite layer may include one or more carbon-fiber-reinforced thermoplastic prepreg plies. A laminate structure may include: a first aluminum layer; a first glass composite layer adjacent to the first aluminum layer; a first carbon composite layer adjacent to the first glass composite layer, and opposite to the first aluminum layer; and/or a second glass composite layer adjacent to the first carbon composite layer, and opposite to the first glass composite layer. The first glass composite layer may include one or more glass-fiber-reinforced thermoplastic prepreg plies. The first carbon composite layer may include one or more carbon-fiber-reinforced thermoplastic prepreg plies.

The disclosure relates to polymer-containing composite materials and to unusually low-pressure consolidation methods for forming composite parts from such materials. More specifically, for example, the disclosure relates to use of a certain “PEEK-PEDEK” copolymer in low-pressure consolidation methods, using as little as 1 bar pressure (or using atmospheric pressure acting on a consolidation that is held under vacuum) to provide composite parts that are substantially void-free.

A structure includes a skin and a foam member. The foam member has a molded contour, the mold contour being configured to provide tooled surface for the skin. When the skin is a composite skin, the foam member provides support for the skin so that the skin can be cured under heat and pressure. A method of making the foam member for a foam stiffened structure includes creating a mold having an interior cavity which resembles a desired shape the foam member. A subsequent step involves introducing a foam mixture into the mold. Next, the foam mixture is allowed to polymerize so as to expand and distribute within the cavity of the mold. The method further includes selectively controlling a density of the foam member in the mold. The foam member is at least partially cured. The foam member is assembled with a skin to produce the foam stiffened structure.

A method of making the asphalt shingles includes applying a substrate to a layer of shingle-forming material, the substrate having indicators at predetermined spaced-apart distances, with the indicators being sensed as the shingle-forming layer is moved along a predetermined path, with adhesive zones being applied to the shingle such that the application of the adhesive zones is synchronized in response to sensing the locations of the indicators, and with the shingle-forming layer then being cut into individual shingles.

A composite structure comprises stacked sets of laminated fiber reinforced resin plies and metal sheets. Edges of the resin plies and metal sheets are interleaved to form a composite-to-metal joint connecting the resin plies with the metal sheets.

The invention relates to a wind turbine blade having a leading edge erosion shield. The erosion shield comprises an inner layer of a first thermoplastic material, the inner layer being an integral part of the shell body of the wind turbine blade. The erosion shield further comprises an outer layer of a second thermoplastic material attached to the inner layer.
