Mechanical And Thermal Characteristics Of Polypropylene Reinforced With Spheri-glass-3000 Produced By Twin Screw Extruder

Continuous Granulation with a Twin-Screw Extruder

Glass Fiber Reinforced Polypropylene Mechanical Properties Enhancement by Adhesion Improvement

Glass fibers (GF) are the reinforcement agent most used in polypropylene (PP) based composites, as they have good balance between properties and costs. However, their final properties are mainly determined by the strength and stability of the polymer-fiber interphase. Fibers do not act as an effective reinforcing material when the adhesion is weak. Also, the adhesion between phases can be easil...

Wet granulation in a twin-screw extruder: implications of screw design.

Wet granulation in twin-screw extrusion machinery is an attractive technology for the continuous processing of pharmaceuticals. The performance of this machinery is integrally tied to its screw design yet little fundamental knowledge exists in this emerging field for granulation to intelligently create, troubleshoot, and scale-up such processes. This study endeavored to systematically examine t...

Static and fatigue behaviour of glass-®bre-reinforced polypropylene composites

This paper is concerned with fatigue of polypropylene/glass-®bre thermoplastic composites produced from a bidirectional woven cloth mixture of E glass ®bres and polypropylene ®bres. The latter becomes the matrix after the application of heat and pressure. This composite was manufactured with a ®bre volume fraction Vf of 0.338. The e€ect of layer design on the static and fatigue performance was ...

Properties of Polypropylene Composites Fabricated Using Twin-screw Extrusion

Sunflower hull sanding dust (SHSD) filled polypropylene (PP) composite was prepared using a twin-screw extruder. Mechanical and thermal properties of the SHSD/PP composite were characterized contrasting to organically modified clay /PP composite. Differential scanning calorimetry (DSC) analysis showed that the crystallization temperature and the degree of crystallinity of PP exhibited changes w...
