An aquatic gliding board which incorporates a subassembly that includes a hollow inner shell which is covered with a casing made of foam capable of being machined. The invention also relates to a hollow gliding board, such as a surfboard, that includes at least one longitudinal partition, such partition(s) connecting upper and lower portions of the subassembly. The partition(s) is (are) made of a foam, such as an elastic foam.

Aquatic gliding board

Laminated composite material usable to make articles of manufacture, such as boots or other sports articles in particular. The laminate is a new basic material particularly directed to articles of manufacture having drastic mechanical requirements and which are very inexpensive and lightweight. The laminate has a sandwich structure having a core between two layers. More particularly, the core and the two layers are composites, and at least a portion of the fibers of the core have a mechanical strength significantly lower than that of at least a portion of the fibers of one and/or the, other layers. In a particular embodiment, the laminate has a thickness of 3 mm or less. The layers are sheets of carbon fabric embedded in an epoxy resin, and the core is made from non-woven polyamide micro-fibers having a thickness equal to 0.32 mm. The invention also relates to the manufacture of the laminate.

Thin composite laminate and use thereof in making sports articles, especially boots

A reinforcement for a boot, in particular a sports boot, more particularly a cross-country ski boot. The boot reinforcement makes it possible to improve the torsional stiffness, efficiency, durability, lightness, cost, foot protection, and industrial workability. To achieve this goal, the boot reinforcement according to the invention includes a front zone A from the front end up to the beginning of the plantar arch, a median zone B corresponding to the plantar arch, a rear zone C. The reinforcement includes, at least in the zones B and C, at least one 'sandwich' structure constituted by at least one core inserted between at least two layers, and, in the zone A, it is flexible in a substantially longitudinal direction and torsionally stiff. The layers of the sandwich structure are made of composite, carbon fibers/polymeric resin, whereas the core of this sandwich structure is made of synthetic foam, wood or honeycomb. Each zone A, B, C has a longitudinal flexural strength RfA, RfB, RfC, such that RfA&#x3c;RfB&#x2266;RfC. The invention also relates to a sports boot including such a reinforcement.

A structural subassembly provided to produce an aquatic gliding board. The subassembly includes a hollow inner shell which is covered with a casing made of foam capable of being machined. The invention also relates to a method of making such a subassembly and to a board made by covering the preceding subassembly with a layer of resin-coated fibers.

A golf club shaft having a hollow body comprised of a fiber and resin composite and a tube-shaped stiffener substantially surrounding a lower portion of the body which comprises a material other than a fiber and resin composite. The stiffener is preferably a metal and comprises a pre-formed sheath.

Golf shaft and method of manufacturing the same

An improved apparatus for manufacturing a reinforced golf club shaft having a complex shape. An inflatable bladder is positioned over a mandrel having a simple shape. Layers of fiber material are then rolled over inflatable bladder to produce a sub-assembly. The sub-assembly is placed in a mold defining a negative of the shape of the final shaft that is to be produced. The impression may have enlarged or narrowed regions for producing irregularities in the shape of the shaft. The bladder is expanded within the mold so that the composite structure is radially displaced and compressed between the bladder and the mold. The inflatable bladder has a variable thickness that conforms to the shape of the impression so that the composite structure undergoes a uniform and minimum displacement along its entire length, which improves the mechanical properties of the final shaft.

A golf ball consisting of a multi-piece cover surrounding a core. The cover consists of a multi-sheet structure which includes at least three thin layers of thermoplastic with each layer having a thickness of no more than 0.030 inches. The hardness of the multi-sheet structure varies between adjacent layers so that the reaction of the ball varies depending upon the amount of deformation of the ball upon impact with a golf club. The method of manufacturing a golf ball includes producing a cover from a multi-layer member, with at least one layer having a thickness of no more than 0.030 inches.

Multi-layer golf ball and method of manufacturing

A solid golf ball having a core, a cover, an intermediate skin between the core and the cover defining a generally continuous inner annular surface, wherein the inner annular surface of the skin is stretched over the core. Desirably, to prevent breakage, the annular surface is at least 1/4 inch wide. Preferably, the skin has a substantially uniform thickness and covers substantially the entire outer surface of the core so that the golf ball will react in a uniform manner regardless of where on the cover the ball is struck. The skin preferably comprises a polymeric material which is stretched so as to have a predetermined amount of initial strain so as to reach a certain level of crystallization of material. This predetermined amount of initial strain is desirably 150%, preferably 200% and, most preferably 400%. A method of manufacturing a golf ball having a stretched intermediate skin is also disclosed.

Process of manufacturing a golf club shaft made of composite materials, including the successive steps of fitting a tubular, flexible impermeable bladder around a rigid mandrel, dressing the mandrel with a composite structure including fibers impregnated with a synthetic resin matrix, placing the mandrel in the mold, and then carrying out a molding operation by applying at least one internal pressure exerted by feeding a fluid inside the bladder.

A solid golf ball having a core, a covers an intermediate layer between the core and the cover formed of a soft elastomeric material. Preferably, the layer has a thickness of 0.1-1.3 mm and is formed by dipping the core into a liquid dispersion latex having a cured hardness between 40 and 100 Shore A. The ball provides improved feel and controllability which can be varied by varying the characteristics of the intermediate layer.

The invention relates to a process for decorating a composite article including the preparation of a decorated complex to be assembled with a reinforcement structure of the article made of a resin, that is capable of flowing when heated, during a subsequent cycle of hot pressing, wherein it includes a first cycle, during which the transfer of a decoration is undertaken using the method for imprinting sublimate ink(s) on the first surface of a layer made of a transparent or translucent plastic material; and a second cycle during which one undertakes, by means of an adhesion film, the hot or press assembly, on the first surface thus decorated, of a contrast sheet made out of a material selected from the group constituted by the non-anodized aluminum, the synthetic dry fiber, wood. The invention enables the decorative patterns to be developed by means of varied and very attractive backgrounds effects, such as woven, metallized or grained backgrounds, depending upon the type of contrast sheet used.
