Materials prepared from biopolyethylene and curaua fibers: Composites from biomass

Polymer 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 ...

Processing and properties of continuous and aligned curaua fibers incorporated polyester composites

Journal of Materials Research and Technology, 2013
AbstractThis paper presents systematic studies carried out on the processing and characterization of continuous and aligned curaua fibers-polyester composites. Laminates of these composites with (0 to 40 vol. %) curaua fibers were press-molded at room temperature, cured for 24hours and tested for strength properties.

Cement composites reinforced by short curaua fibers [PDF]

Matéria (Rio de Janeiro), 2010
The development of an eco-friendly material that could reduce CO2 emission and that could aggregate value to a natural fiber, setting man at the countryside and raising the income of populations from poor regions is a challenge. Lignocellulosic fibers are cheap and are a readily available reinforcement, requiring only a low degree of industrialization ...

Weibull analysis for the diameter dependence of the elastic modulus of curaua fibers [PDF]

Matéria (Rio de Janeiro), 2013
The curaua fiber is one of the strongest lignocellulosic fibers and is currently being considered as reinforcement of polymer composites for industrial applications such as automobile interior components and bicycle helmets. The tensile strength of the curaua fiber was found to display an inverse variation with its corresponding equivalent diameter ...

Ballistic behavior of a hybrid composite reinforced with curaua and aramid fabric subjected to ultraviolet radiation

Journal of Materials Research and Technology, 2018
Mobile ballistic armors, particularly those intended for personal protection, are also designed with lowest possible weight. Composite materials are the best choice for this kind of application, especially laminated composites reinforced with high ...

Performance of natural curaua fiber-reinforced polyester composites under 7.62 mm bullet impact as a stand-alone ballistic armor

Journal of Materials Research and Technology, 2017
A multilayered armor system (MAS) is intended to personal protection against high kinetic energy ammunition. MAS layers are composed of materials such as a front ceramic and a back composite that must show both high impact resistance and low weight ...

Mechanical properties of composites with graphene oxide functionalization of either epoxy matrix or curaua fiber reinforcement

Journal of Materials Research and Technology, 2020
In the present work, two types of composites were produced, both reinforced with 30 vol% of curaua fibers (CF). In the first type, only the fiber was functionalized with graphene oxide (GO), producing the GOCF/EM composite.

Curaua fiber reinforced high-density polyethylene composites: effect of impact modifier and fiber loading [PDF]

Polímeros, 2016
Short fibers are used in thermoplastic composites to increase their tensile and flexural resistance; however, it often decreases impact resistance. Composites with short vegetal fibers are not an exception to this behavior. The purpose of this work is to
