Pre-yield tensile set of a semi-crystalline polymer, its blend and composite

Tensile set was studied at low strains on polypropylene, aliphatic polyketone, rubber toughened blends and CaCO 3 particle toughened composites. The rubber in the rubber toughened blends had a particle size of 0.7 lm. The CaCO 3 particles had a size of 0.7 lm and had been coated with stearic acid.Step-cyclic loading was applied in 1% strain incrementals at a strain rate of 10 -2 s -1 . The maximum strain applied was 20%. The temperature of the test bar was studied with an infra-red camera. Pre-yield deformation is normally assumed to take place in a nonlinear elastic manner. However, for polypropylene and polyketone elastoplastic deformation starts at low strains. For PP the onset of tensile set is at very low strains and increases with strain. The tensile set at the yield point was only 50% and at the drawing strain 100%. Polyketone had a similar tensile set development but shifted to slightly higher strains. Here too the tensile set at the yield point was about 50% and at the drawing strain 100%. The temperature of the non yielded material was found to rise in polyketone a 7°C.The rubber toughened blends had at low strains a higher tensile set, but after the yield strain the set was similar to the base polymer. At 5% strain the tensile set increased with rubber content. The sub micron CaCO 3 particle toughened composites increased the tensile set too. The tensile set is a simple technique for studying the pre-yield behaviour of multi phase systems.

“…It is clear that in aPKeCaCO 3 the voids are present up to the fracture plane. The aPKerubber blend has a relaxation layer next to the fracture surface [29]. Such a relaxed layer was not observed in these aPKeCaCO 3 composites.…”

“…These aPK have a high yield stress and high unnotched fracture toughness; however, with a notch they fracture in a brittle manner. The aPK can be toughened with rubber particles at the cost of the modulus [29]. Studies are on whether aPK can be toughened with CaCO 3 particles and how effective is this toughening when compared to rubber particles.…”

ABSTRACT:The linear viscoelastic behaviors of nylon1212 blends toughened with (styrene-[ethylene-(ethylene-propylene)]-styrene block copolymer) (SEEPS) elastomer were carried out. The results show that dynamic storage modulus (G 0 ) curves of the blends are located between those of virgin nylon and SEEPS within the frequency (x) tested, and the G 0 of blends increases with increasing of the SEEPS content. Moreover, the predictive results of Palierne emulsion model show that it is unsuitable for describing the viscoelastic behaviors of the double phase systems toughened with elastomer, especially for the system with high content of elastomer. The positive deviation in the plots of G 0 vs. blend composition demonstrates that the blends are immiscible. From the point of phase transition, the phase inversion region for these blends was predicted to be in the range of 30-50 wt % of SEEPS, which agrees with the morphology analysis of nylon1212/SEEPS blends. In addition, ''Cole-Cole'' plots of modulus at different temperatures show that the microstructures of blends are unstable in the phase transition region.
