Patent number: 11179901Abstract: A method and an apparatus for molding composite articles are disclosed. The method generally involves the saturation of reinforcing fibers (e.g. glass fibers, carbon fibers, etc.) with a matrix (e.g. resin, epoxy, cyanate ester, vinyl ester, polyester, etc.) in/on a mold using a conventional resin transfer molding (“RTM”) process (e.g. “RTM-light”) or a vacuum assisted resin transfer molding (“VARTM”) process (e.g. advanced VARTM or “A-VARTM”), and, once saturation is completed, the vibration of the matrix-infused fibers using controlled ultrasonic sound waves transmitted through the mold. By vibrating the matrix-infused fibers with the ultrasonic sound waves, the method and apparatus allow voids present between fibers to be closed and localized pockets of gases to be dislodged and degassed, and also allow the fibers to compact, thereby producing composite articles with reduced porosity and higher compaction.Type: GrantFiled: January 8, 2019Date of Patent: November 23, 2021Inventor: Eric Hurdle

The cutting mechanism (40) is moved in a return path from the completion of the cutting path in the extrudate direction away from the die face (18), away from the conveyance mechanism (12), and then towards the die face (18) to the initiation of the cutting path. The cutting mechanism (40) is spaced from and does not physically contact the conveyance mechanism (12) at all times in the cutting path so that the individual piece is cut from the extrudate in mid-air.Type: ApplicationFiled: May 8, 2009Publication date: November 11, 2010Inventors: James N. Weinstein, Susan M. Hayes Jacobson, Terry G. Reishus, Cara J. Sekerak, Michael Viland, Laura Burant

Publication number: 20100180407Abstract: Apparatus and process are described for forming projections on a substrate for use as hook-type fasteners in touch fastening systems, wherein vibration energy may be used to soften a substrate which may be positioned between a mold and a source of vibration. The mold may include a plurality of cavities into which the softened substrate may be forced to form the projections. The substrate may comprise a film, sheet, web, composite, laminate, etc. and be useful as an attachment strip for temporary or permanent fastening. The source of vibration may be an ultrasonic horn. The process to form such projections may be operated in a continuous, semi-continuous or intermittent manner.Type: ApplicationFiled: January 20, 2010Publication date: July 22, 2010Inventor: Gerald ROCHA

Publication number: 20090324765Abstract: An apparatus for the forming of a lay-up of fibre composite material, in particular in the aerospace sector is provided. In this case, the apparatus has at least one forming tool, which has a surface contour corresponding to a desired geometry of the lay-up after the forming, and a tool carrier, to which the at least one forming tool is releasably fastened. From a further viewpoint, the invention makes available an apparatus with a modular structure, it then being possible for any desired forming tools to be combined with the tool carrier according to requirements. This leads in particular to less laborious handling, since it obviates the need for handling of the comparatively large tool carrier.Type: ApplicationFiled: March 31, 2008Publication date: December 31, 2009Inventors: Hauke Lengsfeld, Olaf Rocker, Rainer Graeber
