A manufacturing process and the semi-finished product of thermoplastic material obtained therefrom, for obtaining products with aesthetic patterns which can be perceived in semitransparency also in depth is disclosed. The process includes: (i) producing at least two initial elements of thermoplastic material with even but different aesthetic patterns, having a different concentration of the dominating coloring, at least the dominating coloring being of the bleeding type in the specific thermoplastic material; (ii) shaping the two initial elements into strips or loaves being of a submultiple width, not below ⅕ of a characteristic dimension of the desired finished product; (iii) inserting at least two of the strips or loaves having different concentration of the dominating coloring, into a workform, arranging them side by side according to a direction of side-by-side arrangement; and (iv) undergoing pressure and heat to allow the melting and hardening of the thermoplastic material into a single body.

A method of forming a barrel portion including obtaining a mandrel shaped to define at least an inner surface of a barrel portion of the bat, wrapping a first plurality of layers of fiber composite material about the mandrel, placing a removable material over a first portion of the first plurality of layers, and wrapping a second plurality of layers of fiber composite material over the removable material and the portion of the first plurality of layers not covered by the removable material for form an assembly. The method further includes separating the mandrel from the assembly, inserting an expandable member within the assembly, inserting the assembly into a barrel-forming mold, and molding the assembly in a single molding cycle, curing the first and second layers with the removable material to form the barrel portion of the bat, and removing the removable material and the member from the barrel portion.

Embodiments disclosed herein relate to polymer resins having a first thermoset and one or more additional components (e.g., a second thermoset and/or a thermoplastic), composite laminates including the same, methods of making and using the same, and composite laminate structures including the same.

Methods of compression molding polymeric parts for improved impact resistance are provided. The components are particularly suitable for use in a vehicle or an automobile. The compression molded polymeric component comprises a central region or core comprising integrally formed foam, e.g., a foam core, that can sustain high impact load and does not lead to visible surface cracking or material cracking. The polymeric component may be a reinforced plastic composite (FRP). Such methods can produce lightweight, impact resistant, FRP components that may be used in various structural applications, including in automobiles.

A lightweight composite material includes a substrate and a carbon fiber layer. The substrate has a first surface and a second surface opposite to each other, and is prepared by impregnating glass fibers with a resinous matrix which is formed by mixing hollow glass microspheres with a thermosettable resin material. The carbon fiber layer is bonded to one of the first and second surfaces of the substrate by thermosetting the thermosettable resin material.

Aspects hereof relate to a multi-part mold for molding articles of footwear having sole regions of differing materials forming a desired outsole surface material pattern. The multi-part mold includes a carrier mold portion and a tray mold portion. The carrier mold portion provides definition to the lateral surfaces of a resultant co-molded product. The tray mold portion cooperates with the carrier mold portion and provides definition to another (e.g., bottom) surface of the resultant co-molded product. The tray mold portion generally includes at least one pod or cavity for receiving a first material that when cured/catalyzed, defines a patterned other (e.g., bottom) surface of the resultant product. A multi-part mold having the structure as described herein permits interchangeability of multiple tray mold portions with a single carrier mold portion.

Waterproof, breathable garments and methods of making are provided. The garments may include a laminate of a seamless ePTFE membrane and at least one textile. The garment is conformable over a range of sizes, and may be shaped to fit numerous sizes and shapes of forming molds. The ePTFE membrane may shrink to fit, or, alternatively, be stretched to fit, a mold having a desired size to form a garment. Such a conformable ePTFE membrane may allow for forming multiple sizes of garments with various sizes and shapes of molds. In embodiments where the ePTFE membrane is seamless and continuous, the garment eliminates the need for a waterproof seam tape, which is conventionally used to make garments waterproof.

A composite foam article is disclosed herein. The composite foam article comprises a polyurethane foam core presenting a first surface and a second surface facing opposite the first surface. A first skin is disposed on the first surface and a second skin is disposed on the second surface. The polyurethane foam core has a density of 15-80 kg/m.sup.3. The first and second skins comprise a plurality of fibers and a polymeric binder. The composite foam article has a weight per unit area of 500-1000 g/m.sup.2 and a strength of greater than 17 N at a post-compression thickness of greater than 2 mm when tested in according with SAE J949 at 23° C.

A method may include placing a dry fabric over a tool; pressing a first resin film over the dry fabric while the dry fabric is draped over the tool to create an outer layer of the laminate composite structural component; repeating the placing and pressing process until a desired thickness of the outer layer is achieved; compressing a second resin film and a dry fiber fabric between two rollers to tack the second resin film to the dry fiber fabric to create a resin-fabric sheet comprising a resin film layer and an dry fiber fabric layer; cutting the resin-fabric sheet to a pre-determined shape to create at least one resin-fabric preform; and draping a first resin-fabric preform over at least a portion of the outer layer, wherein one or more edges of the first resin-fabric preform overlap the outer layer to create an internal edge.

The present invention provides, medical rubber parts that do not physically and chemically affect the quality of preparations. The present invention relates to a medical rubber part obtained by press-molding an unvulcanized rubber mainly containing a rubber for forming a liquid-contacting portion and an unvulcanized rubber mainly containing a butyl-based rubber for forming a non-liquid-contacting portion, wherein a color difference dE between the liquid-contacting portion and the non-liquid-contacting portion is 6.0 or more in NBS units.
