Effect of Sisal Fiber Surface Treatments on Sisal Fiber Reinforced Polypropylene (PP) Composites
Advanced Materials Research, 2014Abstract: 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

Flexural Strengthening of RC Beams with Sisal Fiber Composites and Sisal Fiber Rods
Materials Science Forum, 2016The present study is conducted to examine the effectiveness of sisal fiber in flexural strengthening of reinforced concrete (RC) beams. In order to obtain this objective, two different strengthening configurations are adopted (use of sisal fiber composites and use of sisal fiber rods). A total of five flexural strengthened reinforced concrete beams are

Composites Part A: Applied Science and Manufacturing, 2010
Abstract Sisal fibers were mercerized, under tension and no tension, to improve their tensile properties and interfacial adhesion with soy protein resin. Mercerization of fibers under tension is known to minimize fiber shrinkage and to lower the microfibrillar angle by aligning them along the fiber axis. Mercerization improved the fracture stress and

Polymer Composites, 2017
Sisal fiber (SF) and waterborne polyurethane adhesive were used to prepare SF‐based sound absorption material through hot press molding. SF with elastic polyethylene (PE) film interlayers was also fabricated as a new type of sound absorbing composite. The effects of SF treatment methods and PE film on sound absorption coefficient were evaluated.

Sisal fiber‐reinforced green composites: Effect of ecofriendly fiber treatment
Polymer Composites, 2017This research endeavor explores the effect of economical and environment‐friendly treatment of sisal fibers, prior to their incorporation into poly‐lactic acid (PLA). Biocomposites incorporating sisal fibers (30% [w:w]) treated with sodium bicarbonate (10% [w:v]) aqueous solution for varying time periods (24, 72, 120, and 168 h) were developed using ...

Some structural aspects of sisal fibers
Journal of Applied Polymer Science, 1976A critical account has been presented of the recent investigation on the chemical modification of lignocellulosic sisal fibers. The molecular structure of the paracrystalline cellulose, which forms the major constituent of the fiber, was studied by x-ray diffraction technique.

Rheological characterization of HDPE/sisal fiber composites
Polymer Engineering & Science, 2007AbstractThe present paper summarizes an experimental study on the molten viscoelastic behavior of HDPE/sisal composites under steady and dynamic mode. Variations of the melt viscosity and die swell of the composites with an increase in shear rate, fiber loading, and coupling agent concentration have been investigated using capillary rheometer.
