Abstract: A composite hat stringer for stiffening a panel includes a plurality of composite fabric plies arranged to form a cap, a pair of flanges and a pair of webs respectively connecting the cap with the pair of flanges. The cap includes at least one 0° composite tape ply interleafed in the composite fabric plies within the cap.

Abstract: A method, apparatus, and system for managing a composite part. An acceptable level of a warpage is identified for the composite part. The warpage for the composite part is a change in the composite part as manufactured that deviates from design specifications for the composite part. Orientations in a stacking sequence for plies in the composite part are selected that result in the composite part having the acceptable level of the warpage and a desired strength to form selected orientations. The composite part is manufactured using the selected orientations.

Abstract: A material system may include: an aluminum layer; a glass composite layer adjacent to the first aluminum layer; and a carbon composite layer adjacent to the first glass composite layer, and opposite to the first aluminum layer. A method of manufacturing a material system may include: stacking an aluminum layer, glass composite layer that may include thermoplastic prepreg plies, and carbon composite layer so that the aluminum layer is adjacent to the glass composite layer, and the glass composite layer is adjacent to the carbon composite layer; and consolidating the thermoplastic prepreg plies to soften the aluminum layer. A method of manufacturing a material system may include: stacking an aluminum layer, glass composite layer that comprises thermoplastic resin, and carbon composite layer so that the glass composite layer is between the aluminum and carbon composite layers; and adjusting temperature and pressure to consolidate the stack.

Abstract: 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.
