Experimental investigation on tribological behaviours of PA6, PA6-reinforced Al2 O 3 and PA6-reinforced graphite polymer composites

Simple Method for the Preparation of Composites Based on PA6 and Partially Exfoliated Graphite

Melting of PP/PA6 Polymer Blends in Single Screw Extruders – An Experimental Study

A prototype modular single screw extruder fitted with a screw extracting device is used to monitor melting of an immiscible polymer blend (PP/PA6, with different weight ratios) in this popular type of processing equipment. As anticipated, the observed phenomena are much more complex than those involved in extruding PP or PA6, when the well known Maddock/Tadmor mechanism is valid. Consequently a...

Interfacial studies of polyamide 6 composites filled with oxidation carbon fiber

In this work, ozone modification method and air-oxidation are used for the surface treatment of polyacrylonitrile(PAN)based carbon fiber. The surface characteristics of carbon fibers are characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber reinforced polyamide 6 (CF/PA6) composites are investigated by means of the single fiber pull-out tests. As a ...

Lactoferrin suppress the adipogenic differentiation of MC3T3-G2/PA6 cells.

Lactoferrin accelerates the differentiation of osteogenic and chondrogenic lineage cells, whereas it inhibits the myogenic and adipogenic differentiation of pluripotent mesenchymal cells; however, the effect of lactoferrin on the differentiation of preadipocytes is unknown. In this study, we examined the effect of lactoferrin on adipogenic differentiation using a mouse preadipocyte cell line, M...

Fracture Failure Mechanisms of Long Single PA6 Fibers

The present study investigates the failure mechanisms of industrial fiber materials, using a custom designed fiber cutting performance test bench. The fracture morphologies of single PA6 fibers are examined by scanning electron microscopy. The analysis reveals that fiber cutting can be distinguished according to four distinct stages of fiber failure represented by shearing, cutting, brittle fra...
