Technical Article Briefs
Using graphene to toughen rigid poly(vinyl chloride)
The easy dispersion and high flexibility of crumpled multi-layer graphene permit a novel manufacturing approach for nanocomposite materials.
Properties of polyamide-6/cellulose composites enhanced by lignin-containing fibers
The mechanical properties and stability of cellulose-fiber-reinforced polyamide-6 can be improved by carefully controlling processing properties, employing a lubricant, and using high-lignin-content fibers.
Interparticle confinement in nanocomposites
In addition to their reinforcing potential, nanoparticles may affect properties indirectly by acting on the polymer matrix of a nanocomposite, in particular through nucleation and interparticle confinement.
Conformal cooling efficiencies in stretch blow molding
Simulating and measuring mold temperatures and stress crack performance helps improve quenching and petaloid base performance.
Investigating rapid heat cycle molding
New molding technology affects the mechanical properties of fiber-reinforced polymer materials.
Interfacial modification of alkali-treated kenaf fiber
The creation of a compatible interface with a polymer matrix enhances the interaction between the fibers and unsaturated polyester composites.
Magnetite nanocomposite films for radiation shielding
Light and flexible polyvinyl alcohol films containing magnetite nanoparticles 6-11nm in diameter provide shielding from gamma rays.
Evaluating the effects of low-velocity impacts in sandwich composites
A new 3D numerical simulation approach considers facesheet intralaminar damage, interlaminar delamination, and honeycomb plastic deformation, as well as compression after impact.
Predicting shrinkage of plastic films and sheets
A new relaxation model has been developed to predict the level of shrinkage that occurs during continuous annealing processes.
Dispersion of graphite nanoplates during melt mixing
The behavior of pristine and functionalized particles within polypropylene was investigated with the use of a prototype small-scale mixer.
Investigating the crystallization behavior of poly(lactic acid) materials
The poly(L-lactide)-to-poly(D-lactide) block length ratio of star-shaped asymmetric stereoblock copolymers is a key control on the crystallization of stereocomplex crystallites.
Improved processability of linear low-density polyethylene copolymers
Increasing short-chain branching length by even just a few carbon atoms reduces extrudate distortion.
Efficient manufacturing of lightweight composite car seats
A new optimization approach combines the use of fiber-reinforced materials, laying and stacking design methods, as well as integrated forming and injection molding processes.
Tuning the structure of microcellular-injected polypropylene
A new microcellular injection process that uses gas counter pressure and movement of the core-back mold results in low-density polypropylene parts with well-controlled cellular structures.
A walk around the color sphere
The size distribution of titanium dioxide pigment particles affects the whiteness they impart to a plastic article.
Reducing the water uptake of environmentally friendly polypropylene composites
Spent coffee ground particles are treated with a fatty acid derivative in a novel hydrophobic method that improves particle dispersion and impact properties.
Enhancing the properties of low-density polyethylene composites
Mechanical treatment, with the use of a Supermasscolloider, of sugar cane bagasse significantly improves the mechanical and thermal characteristics of composites made with this material.
New impact-modified polycarbonate/polyester blends
A refractive index matching approach can be used to develop transparent/translucent materials with improved impact strength and transmittance properties.
Influencing the strength and biodegradability of polylactide blown films
The morphology and enzymatic degradation of polylactide compositesâ€â€plasticized with acetyl tributyl citrate and blended with glycidyl methacrylate-grafted poly(ethylene octene)â€â€have been investigated.
