News in brief - March/April 2003

Connect, no. 123, March/April 2003, p.8


TWI's low density, fire resistant and thermally insulating material has been granted a patent covering Europe, South Africa and Australia. The US patent is pending, and should be granted in 2003/4. This means that companies now have the opportunity to obtain licenses from TWI to manufacture Barrikade Binder systems, for pre-coating of vermiculite to produce the hard nuggets that make up Barrikade, or for the fabrication of end products, including spraying on to various substrates.

Due to the versatility of the Barrikade material, it can be modified to produce required properties, and end applications, and combined with a range of binder systems for bonding and producing composite components.

TWI's research and development work will continue to investigate new products and applications for Barrikade, such as fire doors, interior walls for buildings, EMI shielding, stealth coatings, sound attenuation and cavity wall insulation.

2002 SMART Fellow Awards

The latest recipients of SMART Fellowships were announced at the European Surface Mount Conference held in Brighton at the end of 2002. SMART Fellowships are awarded to individuals to thank them for their active participation in the furtherance of aiding the electronics manufacturing industry. This year, one of the recipients was Gordon Pryor of TWI who has been instrumental in the EPPIC-Faraday project.

New offshore Group Sponsored Project

TWI has recently launched a new Group Sponsored Project to examine materials selection for dissimilar joints in subsea hub applications.

Steel to weld-deposited nickel alloy interfaces exist in a wide variety of components, either where nickel alloy claddings are used or where there are dissimilar joints between steels and a range of corrosion resistant alloys. The project will address the concerns raised by recent failures in subsea hubs using A1S1 8630 and ERNiCrMo-3/ERNiCrMo-15 combinations by exploring the variables influencing the failure.

Once the controlling factors have been identified, guidelines for the safe manufacture and use of steel to nickel alloy joints in subsea applications will be formulated.

The project began in January 2003 with five sponsors, ABB Vetco Gray, Chevron Texaco, Cooper Cameron, FMC and Statoil. For further information contact the project leader, Andrew Leonard.
