Search in Google ScholarPA6 can absorb up to 7% (by weight) water under high humidity or submerged in water. This can result in dimensional changes up to 2% and a corresponding reduction of physical properties. Proper design techniques can frequently compensate for this factor.

Some conclusions are presented here. Surface fractography of the plate treated by the three routes: (a) and (d) route I (b), (e) route II, and (c) and (f) route III, in which (a)–(c) were obtained with a magnification of 500, and (d)–(f) were obtained with a magnification of 1,000 times. From the aforementioned comparisons, it can be concluded that the dimensional accuracies of the undried parts treated by route II are the highest for the peripheral dimensions and the diameter of the central hole. Nevertheless, its corresponding dried part can also basically meet the accuracy requirements. But in the usage of the plate, moisture should be prohibited to ensure its insulating and antibreakdown properties; hence, re-drying after the boiling water bath is recommended. 4.2 Mechanical property improvements of the plate treated by the three routes Effect of hygrothermal aging on mechanical and tribological behaviors of short glass-fibers-reinforced PA66.

Performing measurements using a micrometer showed that the dimensional accuracies were improved after the three treatment routes; however, there exist some nonnegligible differences between the accuracies obtained with the three routes. 4.1.1 Dimensional accuracy of the central holecycles, in every cycle: −40 to 130°C, 10°C/h, the highest and lowest temperatures were maintained for 4 h, room temperature was maintained for 2 h.
