Brief Abstract:
This activity aims at conducting an FMEA study to analyze the different impacts and effects on the quality of adhesively bonded structures for automotive sub-assemblies. The study implements experimental and modeling efforts to capture the effect of each process (operational window) on the final quality of bonds. Additionally full analyses e.g. thermo-gravimetric, viscosity are done for the adhesive material to evaluate its sensitivity to environmental conditions (humidity) and curing profiles.
Impact:
Better understanding of the effects of each process from the manufacturing chain on the final bond quality. Reduction in quality issues and defects counts.
Project Schedule:
Initiated in 2007 and completed in 2008

Preliminary Results:
New processes control windows have been developed.Improved engineering standards with more specific testing procedures.
Root cause database for the different defectives encountered.
