Production and Evaluation of Biodegradable Composites Based on Polyhydroxybutyrate and Polylactic Acid Reinforced with Short and Long Pulp Fibers
In this study, two biodegradable polymers, polylactic acid (PLA) and polyhydroxybutyrate (PHB), were mixed with short and long fiber pulps using a torque rheometer. PLA/PHB-fiber composites consisting of up to 40 wt% paper pulp were produced through a unique procedure and evaluated using various techniques including thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray dif...
متن کاملEffects of Biomass in Polyethylene or Polylactic Acid Composites
There is need for bioplastics to replace some of the total petroleum plastics used in the world, and help alleviate environmental pollution. Compounding bioplastics with Polyethylene (PE) or Polylactic acid (PLA) containing a dairy-based bioplastic resulted in composites with good mechanical properties. In this study, mass ratios of a dairy-protein-based material (DBP) ranging from 0, 5, 10 and...
متن کاملPREDICTING THE STIFFNESS OF BIAXIAL BRAIDED FIBER COMPOSITES BY INCORPORATION OF CARBON NANO FIBER
In this study, carbon nano fibers (CNFs) were mixed into epoxy resin through a magnetic stirrer and again mixed using ultra sonicator. Using hand layup technique, biaxial braided fiber composites were prepared with unfilled, 0.2, 0.5 and 1 wt% CNF. Tensile test and shear test was performed to identify the tensile strength and shear strength of the composites. Fractured surface of the tensile sp...
متن کاملPolylactic acid composites incorporating casein functionalized cellulose nanowhiskers
BACKGROUND Polylactic acid (PLA) is considered to be a sustainable alternative to petroleum-based polymers for many applications. Using cellulose fiber to reinforce PLA is of great interest recently due to its complete biodegradability and potential improvement of the mechanical performance. However, the dispersion of hydrophilic cellulose fibers in the hydrophobic polymer matrix is usually poo...
متن کاملFlow, strength, stiffness and radiopacity of flowable resin composites.
OBJECTIVE This study was undertaken to characterize 9 currently available proprietary flowable composites with respect to key properties of flow, flexural strength, stiffness (modulus of elasticity) and radiopacity. METHODS Seven proprietary flowable composites (Aelite Flo, Filtek Flow, Heliomolar Flow, PermaFlo, Revolution Formula 2, Tetric Flow, Wave) and 2 flowable compomers (Compoglass Fl...
