Preparation and characterization of vinyl silane crosslinked thermoplastic composites filled with natural fibres
(University of the Free State (QwaQwa Campus), 2012-12)
In this work sisal nanowhiskers (SNW) extracted from sisal fibres were used to reinforce polyethylene matrices, high-density polyethylene (HDPE) and low-density polyethylene (LDPE). The nanocomposites were prepared by ...
The effect of crystalline phase morphology on the structure and properties of polypropylene impact copolymers
(University of the Free State (Qwaqwa Campus), 2012-12)
The present study covers the preparation and the characterisation of β-nucleated impact polypropylene copolymer (NA-IPC), and its fractions prepared through temperature rising elution fractionation (TREF). Calcium stearate ...
The morphology and properties of EVA/Malaysian empty fruit bunch composites
(University of the Free State (Qwaqwa Campus), 2010-12)
Composites based on ethylene vinyl acetate copolymers (EVA18 and EVA28) containing different vinyl acetate (18 and 28% VA) contents and empty fruit bunch (EFB) fibre were studied in this project. The EVA-EFB composites ...
