Golf club patent
VARTM cuts costs
US THERMOPLASTIC composites supplier Phoenixx TPC has been awarded a patent for its reinforced thermoplastic golf club shafts. Phoenixx has developed a manufacturing technology and claims to be the only company currently producing golf club shafts from high performance thermoplastic composites. The patent covers the process for manufacturing tapered tubular thermoplastic composite products, not just golf shafts, although that is the chief application at present. The company has other patents pending for its thermoplastic composites and manufacturing processes. David Park, company president and co-inventor of the process, says that the future will
LOCKHEED Martin Space Systems (LMSS) has demonstrated the capability of vacuresin um-assisted transfer moulding (VARTM) to form one of the largest and most complex composite components of its Trident missile system. Costs are reduced substantially over existing production methods because the structure is produced as a single co-cured item rather than as many separate items bonded and fastened together. In a demonstration project carried out by its Advanced Technology Centre working with structural design engineers from the US Fleet Ballistic Missile programme, LMSS produced a quarter section of the equipment bay for the Trident II D5 missile. Labour, time and overall cost were all reduced, with cost savings as high as 75% being made, as the previous 61-part assembly was consolidated into a single item and 376 fasteners were eliminated.
see more and more goods made from thermoplastics. Manufacturing volumes for thermoplastic resins already exceed those for thermoset resins by a factor of eight in the USA. Using thermoplastic composites is said to improve the ‘feel’ for the player and result in a more consistent shot accuracy than those made using thermoset composites. The latest golf shafts are available through leading specialist distributors. In addition to golf club shafts, Phoenixx TPC supplies thermoplastic composites for a variety of aerospace, military/ defence, industrial and leisure applications.

The equipment section accounts for more than half the total structure cost for the D5 missile. The project demonstrated the ability of various infusion techniques to assure uniform resin penetration and distribution, even in complex geometries. Testing of coupons revealed mechanical properties similar to those produced using conventional autoclave routes. Lockheed Martin Space Systems, which has been producing missiles for the US Navy since 1955, hopes that autoclave-free infusion processes like VARTM will contribute towards cost reduction on future submarine launched missiles. ballistic Present Trident II (DS) manufacturing are based in operations Sunnyvale, California.

ORION Aviation, Ohio, USA, has completed developing the tooling for manufacturing composite parts for its Orion-TS 4+2 turboprop aircraft. It claims that the manufactured parts will automatically align and will not require further work during assembly. The tooling is said to produce an improved bond and mating surface that simplifies the surface finishing process of the joining area. The development began with the production of high quality part plugs. To ensure precision and part symmetry, all of the Orion-TS flying surfaces and fuselage were created using computer controlled five axis
milling machines. The computer cut plugs were hand finished to a 1600 grit smooth surface finish, which was transferred to the final moulding tools and then to the manufactured parts. According to Orion, the process eliminates the need to spend extra time working on the part to achieve a proper fit. It says that the tooling removes guess work and reduces the number of steps during assembly, while minimizing the need for tooling, and fixtures.
