Rheological and nutritional properties of corn based extrudates incorporated with selected dehulled legumes (black gram, green gram, lentil and peas) made using low cost collet extruder at 5%, 10% and 15% levels were studied. There was a decreasing trend of all viscosity properties and degree of gelatinization with increase in legumes incorporation level. With increase in legumes incorporation,...

The melting of an amorphous polymer filament through the hot end a material extrusion process is addressed using computational multiphase fluid dynamics coupled to heat transfer. Only flow block investigated. air gap between and interior extruder accounted for. polymer/air interface implicitly tracked by level-set method. system equations solved finite element method with time-marching Three ve...

In order to develop a polycarbonate (PC)/ acrylonitrile-butadiene-styrene (ABS) product with a high content of recycled PC, a low molecular weight virgin PC was added to recycled PC to minimize batch-to-batch property variations in the compounded product. Six PC/ABS blends were prepared on a twin screw extruder by mixing 50 wt% virgin ABS and 0-25 wt% low molecular weight virgin PC with 25-50 w...

Polypropylene/Multiwall carbon nanotubes/Montmorillonite (PP/MWNTs/MMT) hybrid nanocomposites were prepared by using twin-screw extruder incorporating the polypropylene grafted maleic anhydride (PP-g-mA) as compotibilizer is used for better dispersion of nanoclay in the polymer matrix. The effect of MWNTs and MMT on the polypropylene matrix was investigated in terms of mechanical properties of ...
