The Performance of Adhesive Joints (PAJ) - A UK Initiative
To operate effectively, UK manufacturing industry requires consistent test methods to assess engineering materials and their processing routes. The Department of Trade and Industry (DTI) supports this need through the Measurement Technology and Standards (MTS) budget. Adhesive bonding is a key enabling technology for improving the competitiveness of industry. The Centre for Adhesive Technology (CAT), based at TWI, was therefore commissioned by the DTI to establish specific areas where validated test methods would increase confidence in predicting the performance of adhesive joints. The CAT consulted about 100 organisations, by both telephone and direct interview over the period November 1991-January 1992. Opinions from industrial sectors were obtained, including aerospace, automotive, marine, building and construction, machine tools, light engineering, electrical, electronics, precision instruments, packaging and footwear. These views were evaluated, leading to recommendations on priority 'areas for measurement work.
The survey identified measurement methods for use in design, environmental durability and process control as priority areas and five projects were defined. Tendering took place in July 1992 and contracts were placed for work to start in December 1992 to a total value of £5.4m over three years, funded 100% by the DTI.
A brief review of the main results is presented.
