The tensile strength, elongation at failure in the
tensile tests, tearing strength, resistance to accelerated
weathering, and resistance to exposure outdoors of
the six polyamide samples were determined.
Tensile strength and elongation were determined
at various temperatures and humidities after conditioning
the specimens. The test specimens were
cut with die D [10]. The results obtained utilizing
two different machines are described in tables 2
and 3. A typical stress-strain curve obtained with
an autographic strain gage system is shown in
figure 3.
