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 ...

The Development And Characterization Of Curaua Fibers/ Glass Fibers Polyester Composites

International Journal of Advance in Scientific Research and Engineering (IJASRE), 2020
The curaua fiber is one of the strongest ligno cellulosic and is being currently considered as reinforcement of polymer composite for industrial application. The present work investigates the properties of polyester matrix composites reinforced with continuous curaua fiber and E glass fiber. The developed composites will be tested for tensile, bending,

Thermal and mechanical characteristics of polyurethane/curaua fiber composites

Journal of Thermal Analysis and Calorimetry, 2008
Polyurethane composites reinforced with curaua fiber at 5, 10 and 20% mass/mass proportions were prepared by using the conventional melt-mixing method. The influence of curaua fibers on the thermal behavior and polymer cohesiveness in polyurethane matrix was evaluated by dynamic mechanical thermal analysis (DMTA) and by differential scanning ...

Hybridization effect on the mechanical properties of curaua/glass fiber composites

Composites Part B: Engineering, 2013
The aim of this paper was to evaluate the effect of hybridizing glass and curaua fibers on the mechanical properties of their composites. These composites were produced by hot compression molding, with distinct overall fiber volume fraction, being either pure curaua fiber, pure glass fiber or hybrid.

Dynamic and Ballistic Performance of Graphene Oxide Functionalized Curaua Fiber-Reinforced Epoxy Nanocomposites. [PDF]

Polymers (Basel), 2022
Graphene oxide (GO) functionalized curaua fiber (CF) has been shown to improve the mechanical properties and ballistic performance of epoxy matrix (EM) nanocomposites with 30 vol% fiber. However, the possibility of further improvement in the property and performance of nanocomposites with a greater percentage of GO functionalized CF is still a ...
