Neste trabalho, a poliamida 6 (PA6) foi tenacificada com o terpolímero de acrilonitrila-EPDM-estireno (AES), utilizando etileno-propileno-dieno enxertado anidrido maleico (EPDM-MA), como agente compatibilizante. As blendas foram preparadas em uma extrusora rosca dupla corrotacional e, posteriormente, moldadas por injeção. propriedades resistência ao impacto, à tração e morfologia avaliadas. Os ...

The preadipose cell line, PA6, can support long-term hemopoiesis. Frequency of the hemopoietic stem cells capable of sustaining hemopoiesis in cocultures of bone marrow cells and PA6 cells for 6 wk was 1/5.3 x 10(4) bone marrow cells. In the group of dishes into which bone marrow cells had been inoculated at 2.5 x 10(4) cells/dish, 3 of 19 dishes (16%) contained stem cells capable of reconstitu...

The poly(vinylidene fluoride) (PVDF)/polyamide 6 (PA6) interfacial adhesion has been measured, and morphology and mechanical properties of the binary blends have been investigated. The lap shear strength of the PVDF/PA6 pair indicates a high interfacial adhesion, which is evidence for specific intermolecular interactions between the two polymers. Immiscibility of PVDF and PA6 has clearly been o...

Thermoplastic elastomer of PA6/NBR reinforced by various nanoparticles have wide application in many industries. The properties of these materials depend on PA6, NBR, and nanoparticle amount and characteristics. In this study, the simultaneous effect of NBR and graphene nanoparticle content on mechanical, thermal properties, and morphology of PA6/NBR/Graphene nanocomposites investigated by Cent...

The development of lightweight automotive parts is an important issue for improving the efficiency of vehicles. Polymer composites have been widely applied to reduce weight and improve mechanical properties by mixing polymers with carbon fibers, glass fibers, and carbon nanotubes. Polypropylene (PP) has been added to carbon fiber-reinforced nylon-6 (CF/PA6) composite to achieve further weight r...

ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(pan)-based carbon fiber. the surface characteristics of carbon fibers were characterized by x-ray photoelectron spectroscopy (xps). the interfacial properties of carbon fiber reinforced polyamide 6 (cf/pa6) composites were investigated by means of the single fiber pull-out tests. as a result, it...

Poliamit-6 polimerine ilave edilen EPDM elastomeri, malzemenin çekme dayanımı ve elastiklik modülü gibi değerlerini azaltırken cam elyaflar kompozitin kopma uzamasını azaltmaktadır. Dolayısıyla endüstrinin talep ettiği yüksek mekanik özelliklere yani mukavemet, rijitlik üstün kırılma tokluğu (darbe enerjisi) sahip kompozitlerin elde edilebilmesi için elastomer elyaf takviyeli polimer birlikte ü...

The processing during extrusion can be done either in the steady or transient state. In the first case, all components are added continuously in the extruder and the machine produces great quantities of mixed compound. In the transient state, the polymer that will form the matrix is fed continuously in the extruder and all other components are added as a single or multiple pulse. The mixed mate...
