Abstract

Recent developments were oriented on the analysis of the mechanical performance at local (knit lines and welds) and bulk (molded part) areas, with the influence of molding and welding conditions. It has been found that for non-reinforced and reinforced nylon, the mechanical performance in the knit planes and welded areas are approximately equal to the mechanical performance of a base resin (matrix).

The observations on similarities and differences in the formation of knit and weld lines are presented in Part I of this paper. Analysis of mechanical performance at weld at knit lines of various nylons is discussed in Part II.
