Abstract
Data have been obtained regarding the tensile and impact behavior of pure poly(ethylene terephthalate) (PET) and polyamide 6,6 (PA) and blends of PA in PET in concentrations of 5, 10, 25, 30 and 35 percent by weight of PA. The measurements were carried out at −40, 23 and 70°C. Dispersion and sample preparation were carried out in a reciprocating screw injection‐molding machine. All blends exhibited brittle behavior and low strength, when compared to pure components. Although some enhancement of mechanical properties might be realized by orientation, it is suggested that the observed behavior might be attributed to the low quality of dispersion achievable in injection molding process. This conclusion is supported by microscopic evidence.
