This paper presents a characterization of PA6 and the blend PA6+EPDM (60/40) by tensile tests in order to evaluate several mechanical properties for impact resistance applications. Results were found be dependend on test rate (10 mm/min, 250 mm/min 1000 mm/mm). SEM investigation point out homogenous structure. The has better value energy at break, higher speed: v=250 this characteristic break 2...

Polyamide (PA6) and hydroxyapatite (n-HAp) have intrinsic sorption properties for metal ions. Their association by melt compounding allows manufacturing a composite material (PA6/n-HAp) efficient the binding of uranyl rare earth ions (REEs) in acidic solution (in pH range 2–2.5). The shows enhanced capacities (5–7 times) compared with single PA6 material. structuration slightly improves textura...

To enhance the possibilities in lightweight constructions terms of processability and recyclability, fiber reinforced thermoplastics are a promising class materials. In this context, fiber-matrix interface has major influence on mechanical properties composite. With polyamide 6 (PA6) being hygroscopic thermoplastic, effects elevated humidity temperature behavior must be considered [1]. This stu...

In the automotive sector, which is one of sectors where polymers are mostly used, their behaviour and compatibility in secondary processes such as painting coating applications important preference according to usage areas well mechanical thermal properties. this context, it known that surface wettability a polymer material great importance for different application can be stated wetting non-we...

This study was carried out to compare the tribological performances of 35wt.% graphite-added polytetrafluoroethylene (35G/PTFE) composite and 10wt.%PTFE filled polyamide 6 (10PTFE/PA6) polymer blend at different speeds used in rolling bearing applications. Tribological tests were on a pin-on-disc wear test rig sliding 1.0, 1.5 2.0m / under loads 50N 150N. Tests conducted against AISI 316L stain...

Attempts to maintain or expand primitive hematopoietic stem cells in vitro without the concomitant loss of their differentiative and proliferative potential in vivo have largely been unsuccessful. To investigate this problem, we compared the ability of three cloned bone marrow (BM) stromal cell lines to support the growth of primitive Thy-1lo Sca-1+H-2Khi cells isolated by fluorescence-activate...

Abstract Microcellular foamed polymers have been widely used in the traffic field. However, it is difficult to successfully manufacture microcellular products that simultaneously possess good cell morphology, small size, high density, and great surface quality. In this paper, polyamide 6 (PA6) injection foams were manufactured via short-shot core-back foaming process investigate effect of on qu...

The direct flight muscles of Drosophila melanogaster are innervated by the anterior dorsal mesothoracic (ADM) nerve and the mesothoracic accessory (MAC) nerve. Each of the four conspicuously large axons in the ADM nerve serves one of the muscles designated/>aV,/><24 andpa5. Muscle pa4 is additionally innervated by a very small neurosecretory axon. Muscle pa6, also innervated by the ADM ne...
