Bulk fatigue damage evolution in polyamide-6 and in a polyamide-6 nanocomposite

Evolution of collective damage in a polyamide 6–silicate nanocomposite

The microvoiding in crack-tip plastic zone in a partly exfoliated polyamide 6–silicate nanocomposite is investigated through the experimental measurement of microvoid size distribution and the computer simulation in context of nonlinear fracture mechanics. In order to analyze the effect of silicate content on fracture resistance, the evolution of the collective microvoids induced by the silicat...

Expandable graphite/polyamide-6 nanocomposites

Polyamide-6 (PA-6)/graphite nanocomposites were prepared by melt blending, using a variety of graphites, including virgin graphite, expandable graphites and expanded graphite. The resulting nanocomposites were characterized by X-ray diffraction, thermogravimetric analysis, cone calorimetry, and tensile mechanical analysis. Nanocomposite formation does occur, as denoted by the nanometre dispersi...

Flame-Retardant Polyamide 6/Carbon Nanotube Nanofibers: Processing and Characterization

Polyamide 6 (PA6) was melt-blended with an intumescent flame retardant (FR), multi-wall carbon nanotubes (MWNTs), and nanoclay particles to produce multi-component FR-PA6 nanocomposites. FR-PA6 nanofibers were processed from varied nanocomposite formulations via electrospinning. Electrospinnability, morphology, along with combustion and thermal properties of the nanofibers were investigated. Bo...

Flexural strength of polyamide 6 intercalated/exfoliated cements

Polyamide 6 intercalated/exfoliated (PIE) cements are fabricated and characterized. With the reinforcing nanointerphase, the flexure strength of a PIE cement is higher than that of ordinary cements by an order of magnitude. The optimum nanointerphase content is around 10 wt.%. This technique has great potential in developing advanced precast and repair technologies. © 2005 Elsevier B.V. All rig...
