摘要:
A method for manufacturing a golf club having a hollow golf club head which is filled with a gas under pressure. The interior surface of the golf club head is coated with a solidified layer of a sealant material. The pressurized gas permits the use of thinner face plates by compensating for forces generated when the face plate strikes a golf ball. The sealant is preferably applied by rotating the golf club head to coat the interior surface of the golf club head.

The invention relates to a method of bonding two members together utilizing a stack of solid film adhesive and a layer of solid film adhesive, both disposed between the members. A pressure-applying device may be utilized to apply low pressure to force the members together. The pressure may force the stack to compress and expand in varying directions in order to substantially remove air-bubbles between the layer and one of the members. A heating device may be utilized to change the layer and the stack into liquid states in order to bond the members together with a void-free bond-line.

Composite sections for aircraft fuselages and other structures, and methods and systems for manufacturing such sections, are disclosed herein. A method for manufacturing a shell structure in accordance with one embodiment of the invention includes applying composite material to an interior mold surface of a tool to form a skin extending 360 degrees around an axis. The method can further include positioning a plurality of stiffeners on an inner surface of the skin. After the stiffeners have been positioned, a vacuum bag can be installed over the stiffeners and evacuated to press the stiffeners and the skin outwardly against the interior mold surface of the tool. Next, the skin/stiffener combination can be cocured to bond the stiffeners to the skin and harden the shell structure.

A method of transferring an uncured composite laminate skin from a lay-up surface of a male mandrel tool to a female cure tool includes defining multiple vacuum zones on the lay-up surface, each zone corresponding to one of a multiple of portions into which the skin is to be separated. For example, to separate the skin into two portions, a low profile seal of a first membrane to the lay-up surface is formed at a first vacuum zone and a second low profile seal for a second membrane is formed at a second vacuum zone. The method further includes laying up a composite laminate skin over all the vacuum zones; separating the composite laminate skin into portions, for example, a first portion over the first vacuum zone and a second portion over the second vacuum zone; and releasing the portions individually into cure tools having an outside mold line surface.

An apparatus and method for forming a composite workpiece are provided. An electromagnetic field generator induces a current in a susceptor, thereby heating the workpiece in a die cavity. An elastomeric bladder in the cavity is inflated and urges the workpiece against a contour surface corresponding to a desired configuration of the workpiece. Coolant fluid can also be circulated through the die cavity to cool the workpiece. Thus, the workpiece can be heated, formed, and cooled quickly and without substantial heating of other components, thereby reducing the time and energy relative to conventional forming methods.
摘要:
A golf club head comprising a main body portion formed by a steel casting; a face plate formed of forged steel, and having a periphery, a ball striking front face, and a rear side; provisions for joining the periphery of the face plate at the main body portion to form a high strength, forged face plate for the golf club head; and the main body portion forming a first rearwardly re-entrant recess directly communicating with the face plate rear side over the major area of the rear side. The face plate may alternatively consist of consolidated metal powder.
