摘要： Systems and methods for detecting damage in composite components are disclosed. A first attachment feature and a second attachment feature may be coupled to a composite component. A transmitting device may be coupled to the first attachment feature. A receiving device may be coupled to the second attachment feature. A signal may be transmitted from the transmitting device, through the first attachment feature, through the composite component, and through the second attachment feature to the receiving device. The signal may be analyzed to detect damage in the composite component.

摘要： An end effector for the through thickness reinforcement of a fibrous preform includes a needle cleaning material configured to contact a needle to clean resin from the needle during or between through thickness reinforcement operations. The needle cleaning material may extend from a presser foot toward the needle. The needle cleaning material may slidingly engage the needle in response to movement of one of the needle or the presser foot moving (e.g., translating and/or rotating) with respect to the other of the needle or the presser foot.

摘要： An aerospace component may comprise a fiber reinforced composite material. The fiber reinforced composite material includes a plurality of fiber layers and a carbon matrix surrounding the plurality of fiber layers. A plurality of ceramic particles is dispersed in the carbon matrix. A first fiber layer of the plurality of fiber layers may include a carbon fiber, and a second fiber layer of the plurality of fiber layers may include a non-carbon fiber. A hardness of the non-carbon fiber is greater than a hardness of carbon fiber.

摘要： An acoustic liner may include a core with a plurality of resonator chambers, a perforated top sheet coupled to the core, and a backskin coupled to the core. A thermoacoustic speaker including nanomaterials may be coupled to at least one of the core, the backskin, and the perforated top sheet. A voltage may be applied to the thermoacoustic speaker. The thermoacoustic carbon nanotube speaker may create a dynamic excitation within a resonator chamber in the core. The dynamic excitation may change the liner acoustic impedance to achieve optimum noise attenuation over a wide range of frequencies or engine operating conditions.

摘要： During a manufacturing method, a preform is arranged with a plurality of grips. The preform includes a stack of a plurality of layers of material. The grips are disposed along a periphery of the stack. The preform is formed into a shaped body. The forming includes pressing a die against the stack and gripping the stack with the grips during the pressing of the die. The gripping includes asynchronously gripping the stack with at least some of the grips.
