Ionized‐Air‐Treated Curaua Fibers as Reinforcement for Phenolic Matrices

open access: yesMacromolecular Materials and Engineering, 2008
AbstractCuraua fibers were treated with ionized air to improve the fiber/phenolic matrix adhesion. The treatment with ionized air did not change the thermal stability of the fibers. The impact strength increased with increase in the fiber treatment time.

Materials prepared from biopolyethylene and curaua fibers: Composites from biomass

open access: yesPolymer Testing, 2012
AbstractComposites of high-density biopolyethylene (HDBPE) obtained from ethylene derived from sugarcane ethanol and curaua fibers were formed by first mixing in an internal mixer followed by thermopressing. Additionally, hydroxyl-terminated polybutadiene (LHPB), which is usually used as an impact modifier, was mainly used in this study as a ...
