Systems and methods for manufacturing large contoured parts from thermoplastic laminate sheets
A system for manufacturing a part that includes a mold, a first fixation component, fixed to the mold, second fixation components, each configured to be fixed to a consolidated laminate sheet, third fixation components, each fixed to the mold. The system also includes tension straps. The first fixation component is configured to attach the consolidated laminate sheet to the mold so that the consolidated laminate sheet does not translationally move relative to the forming surface of the mold. Each one of the second fixation components is configured to attach the tension straps to the consolidated laminate sheet. Each one of the third fixation components is configured to attach the tension straps to the mold so that the tension straps are movable relative to the mold. The system also includes a heating assembly and a strap retraction mechanism, configured to retract the tension strap.

Method for the design and efficient manufacture of fiber-composite parts
A method for designing fiber-composite parts in which part performance and manufacturing efficiency can be traded-off against one another to provide an “optimized” design for a desired use case. In some embodiments, the method involves generating an idealized fiber map, wherein the orientation of fibers throughout the prospective part align with the anticipated load conditions throughout the part, and then modifying the idealized fiber map by various fabrication constraints to generate a process-compensated preform map.
Molding device and method for producing a shell element reinforced with supporting elements and composed of fiber composite material
A molding device for producing a shell element reinforced with supporting elements and composed of fiber composite material, including a mold part with a mold surface including a cavity for receiving a supporting element of the shell element, and a mold core to be arranged in the cavity and to support the supporting element on the shell element when the supporting element of the shell element is arranged in the cavity. The molding device enables prevention of the mold cores from falling out in an uncontrolled manner when the shell element is removed from the mold as the mold core includes a holding device to engage with the supporting element of the shell element to be produced located in the cavity and to hold the mold core on the supporting element when the shell element to be produced is released from the mold part.

MOLD FOR MANUFACTURING A TURBINE ENGINE FAN CASING FROM A COMPOSITE MATERIAL
A mold for manufacturing a turbomachine fan casing of composite material, includes a mandrel around which a fibrous preform of the fan casing is to be wound; counter-mold angular sectors assembled on the external contour of the mandrel which are intended to close the mold and to compact the fibrous preform wound on the mandrel; wherein each angular sector includes a first lateral flange positioned at the first end of the angular sectors and a second lateral flange positioned at a second end of the angular sectors, the first and second lateral flanges cooperating respectively with the second and first lateral flanges of the adjacent angular sectors. An angular sector includes a first groove formed in the first of second lateral flange, a first seal being positioned in the first groove, the first seal to be compressed between the first and second lateral flanges of two adjacent angular sectors.
SILENCER FOR AUTOMOBILE AND MANUFACTURING METHOD THEREOF
The present invention discloses a silencer for automobile. The silencer is formed by press molding. The silencer has a first molded surface and a second molded surface which are opposite to each other in a thickness direction. The silencer at least includes a first fiber layer on which the first molded surface is formed and a second fiber layer integrated with an opposite surface to the first molded surface, the opposite surface being on the first fiber layer. Fibers of the second fiber layer exist partly on the opposite surface on the first fiber layer.
