Effect of surface treatment on the morphology of sisal fibers in sisal/polylactic acid composites
Journal of Reinforced Plastics and Composites, 2012Sisal 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.

Mechanical Behavior of Natural Sisal Fibers
Journal of Biobased Materials and Bioenergy, 2010Natural 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.

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

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

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.

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

Preparation and characterization of benzylated sisal fibers
Journal of Applied Polymer Science, 2003AbstractSisal 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
