The shape of the tensile bar
is similar to specimen 5A from DIN EN ISO 527-2, and according to DIN 53504 suitable for thermoplastic elastomers.
The transducers were placed with clamps at the surface of the tensile bar
between the sensor arms of the extensometers (Figure 2).
The as-molded samples were then cryogenically fractured at three locations on the tensile bar
with liquid nitrogen, as shown in Fig.
samples were immersed in a 50% aqueous solution (by weight) of zinc chloride for 200 hr at 23 [+ or -] 2[degrees]C.
Furthermore, a jointed tensile bar
had to be constructed to join plates at either end of the Bar to counter a tendency to push out at either side.
Table 2 shows example tensile bar
results from the trials.
Compared with a tensile bar
injected at both ends to form a weld line in the middle, but with no push-pull action, tensile strengths were as much as 177% to 532% higher, respectively.
5 inches) with the impact specimen's center of length corresponding to the center of length of the tensile bar
As test samples, the parallel area between the shoulders of the tensile bar
were used (50 mm x 10 mm x 4 mm).
Both responses from the dynamic tensile bar
analysis are shown graphically in Fig.
The PLA/CSP ecocomposites was compressed into a tensile bar
using compression-molding machine model GT 7014A, Gotech.
