20080286564 | NANOTUBE-ENHANCED INTERLAYERS FOR COMPOSITE STRUCTURES - Carbon nanotube interlayer assemblies, methods of manufacturing carbon nanotube interlayer assemblies, and methods of manufacturing composite parts with carbon nanotube interlayer assemblies are disclosed herein. In one embodiment, a method of manufacturing a composite structure in accordance with an embodiment of the invention includes producing a plurality of carbon nanotubes on one or both sides of a substrate, and attaching the substrate to a first fiber layer. The method can further include positioning a second fiber layer adjacent to the first fiber layer to position the plurality of carbon nanotubes between the first and second fiber layers. The method can additionally include infusing the first and second fiber layers with resin, and curing the resin. In one embodiment, the carbon nanotube substrate can be attached to the first fiber layer by melt-bonding. In another embodiment, the carbon nanotube substrate can be attached to the first fiber layer with stitches. | 11-20-2008 |
20080289743 | HIGHLY POROUS INTERLAYERS TO TOUGHEN LIQUID-MOLDED FABRIC-BASED COMPOSITES - Materials and Methods are provided for producing preform materials for impact-resistant composite materials suitable for liquid molding. An interlayer comprising a spunbonded, spunlaced, or mesh fabric is introduced between non-crimped layers of unidirectional reinforcing fibers to produce a preform for use in liquid-molding processes to produce composite materials. Interlayer material remains as a separate phase from matrix resin after infusion, and curing of the preform provides increased impact resistance by increasing the amount of energy required to propagate localized fractures due to impact. Constructions having the interlayer materials melt-bonded to the reinforcing fibers demonstrate improved mechanical performance through improved fiber alignment compared to other fabrication and preforming methods. | 11-27-2008 |
20100003881 | METHODS AND APPARATUS ASSOCIATED WITH NARROW TOWS FABRICATED FROM LARGE-TOW PREFORMS - A method for using a tow incorporating a large number of fibers to form a composite part that has the quality of parts made with tows incorporating a small number of fibers is described. The method includes spreading the tows incorporating a large number of fibers to form a relatively wide, flat, and continuous, unidirectional fabric, holding the fabric under tension to maintain the orientation and flatness, subjecting the flattened fabric to melt-bonding while held under tension to maintain the flattened configuration, and slicing the melt-bonded, unidirectional fabric into a plurality of narrow fiber tows and subsequently using these to produce braided, woven, and other fabric forms. | 01-07-2010 |
