Effect of Sisal Fiber Surface Treatments on Sisal Fiber Reinforced Polypropylene (PP) Composites

Advanced Materials Research, 2014
Abstract: The Interface of sisal fiber which was treated by using alkali, potassium permanganate, atmospheric plasma and silane reinforced polypropylene composites were investigated by single fiber pull-out testes and surface morphology were studied. The results indicated that the morphological changes observed on the sisal fiber surface were obviously

Preparation and characterization of benzylated sisal fibers

Journal of Applied Polymer Science, 2003
AbstractSisal fibers were benzylated under different conditions and were characterized with infrared spectroscopy, X‐ray diffraction, thermal analysis, and scanning electron microscopy. The benzylation reaction was monitored by the mass gain as a function of the reaction time. In the first stage, there was a mass loss associated with the loss of lignin

Mechanical Behavior of Natural Sisal Fibers

Journal of Biobased Materials and Bioenergy, 2010
Natural fibers are gaining a significant amount of attention as reinforcement in composite materials. In this work we present a systematic experimental investigation on the mechanical performance of sisal fibers. Tensile tests were performed and Young’s modulus determined.

Effect of surface treatment on the morphology of sisal fibers in sisal/polylactic acid composites

Journal of Reinforced Plastics and Composites, 2012
Sisal fibers were pretreated by alkali and alkylation, and then mixed with polylactic acid to make sisal fiber-reinforced polylactic acid composites, respectively. The architecture and aspect ratio of sisal fibers before and after mixing, the micro-morphology of fracture surface, and the properties of composites were investigated.

Investigation on Mechanical Behavior of Sisal Fiber Reinforced Polylactic Acid and Sisal/Epoxy Composites

Key Engineering Materials, 2020
. Natural fibers have been found to be an alternative resource for synthetic materials. Natural composites are found to be a one hundred percent bio degradable product. Natural composites are also found to be having a great strength to weight ratio. In this process, hybrid sisal and polylactic bio composites are reinforced together by using the hand ...

Preparation of Polypropylene/Sisal Fiber Composites and Study on the Fiber Orientation

Advanced Materials Research, 2014
The polypropylene/sisal fiber composites were prepared by twin screw extruder and vane extruder, respectively. The tensile test specimens perpendicular to the extrusion direction and parallel to the extrusion direction were prepared from the extruded composites, respectively.

Recyclability analysis of PLA/Sisal fiber biocomposites

Composites Part B: Engineering, 2019
Abstract This study presents the recyclability analysis of PLA/Sisal biocomposites comprising sodium bicarbonate treated Sisal fibers (30 wt%). The biocomposites were recycled (8 times) using the extrusion process. The tensile strength of injection molded biocomposites declined by 20.9% up to the third recycle.

Interfacial Characteristics of Sisal Fiber and Polymeric Matrices

The Journal of Adhesion, 2006
Sisal-fiber-reinforced composites, as a class of eco-composites, have attracted much attention from materials scientists and engineers in recent years. In this article, the effects of fiber surface treatment on fiber tensile strength and fiber-matrix interface characteristics were determined by using tensile and single fiber pullout tests, respectively.
