Abstract

This thesis is concerned with the linear vibration welding of nylons reinforced with chopped glass fibers. This process and these materials are already used to make automotive air induction modules. To further integrate more parts into these modules, it is sometimes necessary to use higher temperature more expensive amides. The weld geometries used included mainly T-joint samples, and also butt welds were done, and some further analyses were done on CWF and shear samples made previously. Three different Design of Experiments (DOE) matrices were used to create three sets of T-joint samples which were analyzed to understand the interactions among the process parameters. The usual analysis of variance was extended by multivariate analysis to better define the individual roles of each of the process parameters. Cross-sections of the various types of welds were examined. DOE matrices were also performed on butt welds where the samples were either 3 mm thick welded to 3 mm thick samples, or 6 mm thick to 6 mm thick welds. A set of resistance welds was also done, as this method had produced very strong welds in induction heated samples.
