Fracture behaviour of poly[ethylene–(vinyl alcohol)]/organo-clay composites
(WileySociety of Chemical Industry, 2009)
BACKGROUND: Ethylene–(vinyl alcohol) (EVOH) copolymer/organo‐modified montmorillonite (OMMT) composites were investigated. Composites with two different percentages by weight of OMMT were prepared using a melt‐extrusion ...
Effect of the unidirectional drawing on the thermal and mechanical properties of PLA films with different L-isomer content
(Wiley Periodicals, Inc., 2013-02)
This work simulates the thermoforming process of two different L-isomer content PLA grades (95.6 and 98%), studying the influence on the induced morphology and the variation in the thermal and tensile properties. The ...
Adhesion enhancement of powder coatings on galvanised steel by addition of organo-modified silica particles
(Elsevier, 2014-08)
The addition of organo-modified silica particles (OSP) to organic monolayer coatings has been investigated as an alternative to the use of primers or surface pretreatments in galvanised steel substrates. A commercial ...
Effect of the Strain Rate and Drawing Temperature on the Mechanical Behavior of EVOH and EVOH Composites
(Wiley, 2013-03)
The effect of the strain rate and draw temperature on the mechanical behavior of ethylene vinyl alcohol (EVOH) and EVOH composites was analyzed. When EVOH is stretched at moderate strain rates, evidence of strain-induced ...
Effect of the recycling and annealing on the mechanical and fracture properties of poly(lactic acid)
(Springer US, 2010)
The aim of this work is to evaluate the use of Poly(lactic acid) (PLA) industrial waste as a source of raw material for certain applications, as well as to understand the effects of the annealing on the fracture behavior ...
Influence of femtolaser notch sharpening technique in the determination of essential work of fracture (EWF) parameters
(Elsevier, 2009-06)
The fracture behaviour of a 0.5 mm thick ethylene-propylene block copolymer is analyzed using the essential work of fracture method, using DENT-type specimens. The influence of three experimental parameters in the technique ...
The Essential Work of Fracture (EWF) method – Analyzing the Post-Yielding Fracture Mechanics of polymers
(Elsevier, 2009-12)
The Post-Yielding Fracture Mechanics describe the fracture behaviour of pre-cracked films and thin sheets that show yielding phenomenon at the crack tip during fracture. The Essential Work of Fracture method (EWF) has been ...
Modification of Nafion Membranes with Polyaniline to Reduce Methanol Permeability
(Electrochemical Society, 2015)
The modification of Nafion membranes with polyaniline (PAni) has been studied as an alternative for reducing methanol crossover in direct methanol fuel cells (DMFC). The modification has been performed by directly polymerizing ...
Influence of crystallinity on the fracture toughness of poly(lactic acid)/montmorillonite nanocomposites prepared by twin-screw extrusion.
(© 2010 Wiley Periodicals, 2011-04)
The aim of this work was to study the effect of crystallinity degree on the thermal, mechanical, and fracture properties of poly(lactic acid)/organomodified montmorillonite (PLA/OMMT) nanocomposites. Samples with two ...
Fracture behavior of quenched poly(lactic acid)
(BME-PT, 2011)
The effect of a quenching treatment applied on heated cast sheet extruded films of two poly(lactic acid) (PLA)
commercial grades, with different optical purities, was studied. The thermal and mechanical properties of the ...
