  • Patent number: 8617442
    Abstract: A process for the bonding of a fiber-reinforced material to an injection-molding material and an article produced by the process. The process improves the bond between a fiber-reinforced starting material and a material applied by injection. A further plastics material is inserted under pressure into a fiber-reinforced plastics material. This results in interlock bonding between the further plastics material and the fibers of the fiber-reinforced plastics material. This type of bonding is substantially more stable than known bonding.

  • Patent number: 8486321
    Abstract: Polymer articles are often reinforced by addition of fibers which may be assembled into a structured reinforcement such as a woven mat or sheet and the mat or sheet serves as the reinforcement. Such woven fiber-reinforced polymer composite articles may exhibit undesirable variations in surface height which mimic the geometry of the underlying reinforcements, a phenomenon known as print through. By forming, on the surface of the article, a relatively thin, layer of a compatible polymer incorporating closely-spaced, short, carbon nanotubes more or less uniformly dispersed throughout the layer and oriented normal to the article surface, print through may be reduced or eliminated. Methods for fabricating such an article are detailed.

  • Publication number: 20130171409
    Abstract: A system and method for the production of cellular materials. Several geometries such as honeycomb, chiral, auxetic are described. The pre-formation of the cellular structure is by penetration of a reinforcement fabric by means of punches properly structured. Punches housed on one of the matrices of the device allow obtaining several geometries without need of complex fabric pre-formations operations or of manual placement of the fabric in the interstices of the mold.

  • Patent number: 8460592
    Abstract: A hollow golf club head with a concave portion is disclosed and claimed. The club head includes a metallic portion and a light-weight portion, which may be formed of plastic, composite, or the like. The concave portion allows the club designer to make a club head having very thin portions while still maintaining the requisite structural integrity. Convex bulges may optionally be provided to house weight inserts to enhance the playing characteristics of the golf club. The metallic portion of the club head may take on the appearance of a frame, into which several light-weight inserts are positioned. These light-weight inserts may be positioned in the crown, skirt, and sole of the club head. The club head may be formed by co-molding, eliminating the need for welding or adhesives, freeing mass to be used in more beneficial ways. The club head may be large to increase playability and forgiveness.
