Polymers, 2023 Polyamide 4 (PA4) is a biobased and biodegradable polyamide. The high hydrogen bond density of PA4 bestows it with a high melting point that is close to its thermal decomposition temperature, thereby limiting the melt processing of PA4. In this study, PA4 was blended with polyamide 6 (PA6) and further modified with copolyamide 4/6 (R46). The effects of

Polyamide‐6/Silica Nanocomposites [PDF]
Advanced Engineering Materials, 2004 New strategies were developed which incorporate silica nanoparticles (<30 nm) into a nylon‐6 matrix, to form technically interesting hybrid nanocomposites with improved stiffness. Silica particles retained their original shape and size (10–30 nm), are mono‐dispersed and mainly non‐agglomerated as shown by TEM. Mechanical tests on the composites were

Bulk fatigue damage evolution in polyamide‐6 and in a polyamide‐6 nanocomposite
Polymer Composites, 2005 AbstractThe mechanical response of a polyamide‐6 montmorillonite clay nanocomposite and of a polyamide‐6 was monitored during axial fatigue tests performed at R‐ratios of 0.1 and −1. For both materials, two transitions were usually observed in the evolution of all the stress‐strain‐time parameters studied after similar numbers of loading cycles ...

Novel Biobased Polyamide 410/Polyamide 6/CNT Nanocomposites [PDF]
Polymers, 2018 Biobased polyamide 410 (PA410)/multiwall carbon nanotube (CNT) nanocomposites (NCs) were obtained by melt-mixing in a twin screw extruder a Polyamide 6 (PA6)-based masterbatch (with 15 wt % CNT content) with neat PA410. Directly mixed PA410/CNT NCs were also obtained for comparison purposes.

Fatigue crack initiation and propagation in polyamide‐6 and in polyamide‐6 nanocomposites
Polymer Composites, 2004 AbstractRecent developments in polymer nanocomposites have led to improvements in conventional short‐term, but the long‐term mechanical properties have received little attention. The objective of the present study was to characterize the effect of nanoparticles on the fatigue crack initiation and propagation mechanisms and on the fatigue properties of ...

Characterization of polyamide 6 - polypropylene laminates [PDF]
AIP Conference Proceedings, 2019 Wover-fiber reinforced composites become more and more important for lightweight construction components, smart textiles and numerous other applications. The interaction between the two components of the composite depends on the chemical, physical and mechanical properties, and on the manufacturing process of the composite.

Miscibility of Chitosans/Polyamide 6 Blends [PDF]
Polymer Journal, 1997 Chitosans with different degrees of deacetylation were prepared by a chemical method, and miscibility between chitosan and polyamide 6 was examined as a function of the degree of deacetylation in chitosan. From dynamic mechanical analysis and solution viscosity measurement, it may be concluded that there are specific interactions between amorphous ...

Polypropylene/Polyamide 6 in situ Composite [PDF]
Polymer Journal, 1997 The in situ composite consisting of polypropylene (PP) and polyamide 6 (PA6) was obtained with extrusion method in a single screw extruder. It was found that PA6 being the dispersed phase could fibrillated in PP matrix and fibrillation occurred in the channel of the extruder.

Synthesis of Polyamide 6-block-Vinyl Polymers Using New Polyamide 6 Radical Initiators [PDF]
Polymer Journal, 1999 Two polyamide 6 (PA6) radical initiators (PA6ini), AI and AIA types (A : PA6 segment, I : azo group), were prepared from 4,4′-azobis-2-cyanopentanoyl chloride and PA6 prepolymers having controlled average molecular weights. Various PA6-block-vinyl polymers were synthesized by radical polymerizations of vinyl monomers, such as styrene, methyl ...

On Blends of Polyamide 6 and a Hyperbranched Aramid
Macromolecular Materials and Engineering, 2003 AbstractThe hyperbranched (HB) aromatic polyamide synthesised by direct polycondensation of 5‐(4‐aminobenzoylamino)isophthalic acid (ABZAIA) has been solution‐ and melt‐ blended with polyamide 6 (PA6) incorporating different end groups. The concentration of p(ABZAIA) in PA6 has been varied from 5 to 30 wt.‐% in order to evaluate the influence of ...
