Effect of Sisal Fiber Surface Treatment on Properties of Sisal Fiber Reinforced Polylactide Composites [PDF]

International Journal of Polymer Science, 2011
Mechanical properties of composites are strongly influenced by the quality of the fiber/matrix interface. The objective of this study was to evaluate the mechanical properties of polylactide (PLA) composites as a function of modification of sisal fiber with two different macromolecular coupling agents. Sisal fiber reinforced polylactide composites were

Influence of contents of chemical compositions on the mechanical property of sisal fibers and sisal fibers reinforced PLA composites [PDF]

Journal of Natural Fibers, 2018
The influence rule of the content ratio of cellulose, hemicellulose, and lignin on the tensile strength of sisal fibers (SFs) and the interfacial strength of SFs and poly lactic acid (PLA) matrix were investigated. Study showed that the microstructure and mechanic property of SFs were changed by alkali treatment. The proper contents ratio of cellulose,
