Effect of particle size on the surface properties and morphology of ground flax [PDF]

open access: yes, 2013
Flax fibers were ground with a ball-mill and four fractions with different size ranges were collected by sieving. These were tested for water sorption, degree of polymerization (DP), copper number, hydroxyl number and analyzed by X-ray diffraction (XRD),

Modification and Characterization of Hemp and Sisal Fibers

open access: yesJournal of Natural Fibers, 2014
This work is to investigate the effectiveness of the surface treatment technique of fiber impregnation in polymer solution in improving compatibility of natural fibers with matrix. Hemp and sisal fibers were treated through polymer coating in comparison to acetylation, alkalization/acetylation, and silanization.

Comparative Evaluation of Structure–Processing–Property Relationships in Flax, Hemp, and Cattail Discontinuous fiber Thermoset Composites

open access: yesPolymer Composites, EarlyView.
Needle punching reorients fibers from in‐plane direction toward z‐direction of the web, resulting in mechanical interlocking of fibers and reduction in the nonwoven mat thickness. ABSTRACT Replacement of glass fiber mats, utilized in large and complex composite parts in the transportation industry, with natural fiber mats requires knowledge of natural ...

Effects of UV‐Thermal Exposure Sequence on the Compressive Performance of FDM‐Printed Polymers

open access: yesPolymer Engineering &Science, EarlyView.
These findings establish aging sequence as a key design parameter for FDM polymers, enabling safer material selection and improved durability of load‐bearing printed components. ABSTRACT Ultraviolet (UV) radiation and elevated temperatures can alter the compressive performance of fused deposition modeled (FDM) polymers, but the combined effects, and ...

Short-Term Durability of Hemp Fibers

open access: yesProcedia Engineering, 2017
Abstract Short-term durability tests on hemp-fiber confined concrete cylinders made up of one layer of hemp-fiber bundles were conducted to study their behavior. Compression test was performed after wetting and drying cycles in both water and seawater. Moreover, uniaxial tension test on hemp-fiber bundles was conducted to study the effect of extended

Compatibilization and Reinforcement of PHB/PBAT Blends via Sequential Blending of Surface‐Modified Cellulose

open access: yesPolymer Engineering &Science, EarlyView.
Sequential blending improved the mechancial properties of PHB/PBAT/cellulose composites as compared to the one‐step batch mixing method. ABSTRACT Polyhydroxybutyrate (PHB) is a natural and biodegradable polymer generated by bacteria. While its applications to potentially replace petroleum‐based plastics are severely limited due to its brittleness and ...
