Nondestructive testing of defects in adhesive joints

temperature mechanical properties, barrier properties) of the engineering polymers. However, a
success in developing technology for true nanocomposites based on engineering thermoplastics
would take polymers to new market arena, bettering metals with easier processibility,
recyclability, design flexibility and lighter weight. Hence, development of a successful
technology for exfoliation and dispersion of nanoclays in engineering or high-temperature
thermoplastics, would bridge the gap between the technology and the market need with the right
cost-benefit balance. In this presentation, the recent efforts in development of modified nanoclays
for high temperature applications have been reviewed. A comparison of the thermal stability of
the conventional, as well as, of the new high-temperature modifiers, have been made with respect
to the processing temperature required for different common commercial polymers.
An effort is made to give a comprehensive picture of the field from the point of view of the
present status, and the industry needs in terms temperature requirements for melt processing of
different thermoplastics.
