Technical Article Briefs
Microcellular injection molding with improved surface quality
Increasing the interfacial mold-polymer temperature by insertion of an insulator layer allows elimination of bubble tracks on the surface before melt solidification.
Oil-palm fiber as natural reinforcement for polymer composites
The importance of natural fibers as reinforcement or fillers in polymers is increasing, but limitations have prevented them from totally replacing synthetic fibers.
Consolidation and fracture of self-reinforced polypropylene composites
Greater matrix-reinforcement adhesion reduces the number of acoustic-emission events, which also occur nearer to final failure.
Intercalation pathways and mechanical properties of epoxy-clay nanocomposites
Intercalation pathways between galleries impact the strain at failure of epoxy-clay hybrid nanocomposites.
Freeze-thawed hydrogels for modeling blood vessels
Artificial materials that match both the physical dimensions and mechanical properties of biological blood vessels could be useful in biomedical simulation experiments.
Improving melt processing of thermoplastic polyurethanes
Addition of low-molecular-mass-containing urethane groups leads to both a reduction in intrinsic viscosity and an increase in melt-flow stability.
Stability of wood/polyvinyl chloride composites under UV-light aging
UV light affects the mechanical and structural stability of composite materials, which can be reduced successfully by employing an acrylic protecting layer.
Bilateral stress in resin feed is important for solids conveying
Laboratory measurements of the bilateral stress of resin feed samples show that it is unique to polymer type and form.
A unique, high-flow, drapable, soft reprocessable material
A new pelletizable, reprocessable composition can be converted into a nonwoven material or a fabric suitable for spin bonding.
Resin pressure inside composite laminates
Resin pressures are uniformly distributed in the through-thickness and in-plane directions during zero-bleeding autoclave processing.
Visco-elastic properties of modified poly(lactic acid)/ spruce-wood-flour composites
Composite mechanical behavior is critically influenced by interfacial compatibility between the filler and polymer matrix.
Using a torque rheometer to characterize flow in poly(vinyl chloride) composites
An instrument that is basically a batch mixer provides valuable data regarding the processability of polymer micro- and nanomaterials, and is also a useful tool in quality control and product development.
Efficient extruder and slot-die purging
Cleaning an extrusion system can have many benefits, including quick product changeover, reduced contamination defects, and faster, more successful screw removal.
Organoclays enhance photodegradation of polyethylene film
Manganese- and cobalt-based layered double hydroxides intercalated with fatty acids are excellent photodegradation organoclay additives for low-density polyethylene films.
Simulation of parison shape at pinch-off in blow molding
Predictions of the multilayer-parison shape during extrusion blow molding are aided by finite-element calculations.
Improving interfacial adhesion of composites with treated fibers
Surface modification of natural fiber using physical or chemical methods can improve the interfacial adhesion of the composites
Tensile and fatigue properties of a short-fiber-reinforced polyamide-6,6
The effects of melt temperature and hold pressure depend on the fabrication method of injection-molded polymer/fiber composites.
Nanocomposite dispersions based on cellulose whiskers and acrylic co-polymer
Addition of methacryloxypropyl triethoxysilane stabilizes the dispersion and favors anchoring of the whiskers onto polymer particles.
Production of highly transparent polypropylene sheets
A combination of quick quenching and suitable heat treatment can improve the transparency of polypropylene extrusion sheets.
Supercritical carbon dioxide dissolves in potato starch and its derivatives
The solubility of supercritical carbon dioxide in potato starch is in the characteristic range of typical synthetic polymers.
