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 ...

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.

Modificação das propriedades das fibras de curauá por acetilação Modification of the properties of curauá fibers by acetylation

Revista Brasileira de Engenharia Agrícola e Ambiental, 2011
Nos compósitos cimentíceos as fibras vegetais podem sofrer vários graus de degradação quando expostas ao ambiente alcalino. O meio alcalino degrada os componentes macromoleculares das fibras, principalmente pela solubilização da lignina e a desfibrilação
