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

open access: yesJournal 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.

Composites of natural rubber with curaua fibers [PDF]

open access: yesPolímeros
This paper analyzed the thermal and mechanical properties of natural rubber/curaua fiber composite with different weight contents (2.5% to 15%). Alkali treatment was used to modify the surface of curaua fiber and improve interfacial bonding.

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

open access: yesRevista 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

Curaua/polypropylene composites: Phase compatibilization and alternative micromechanics modeling

open access: yesIndustrial Crops and Products
Curaua strands, a natural fiber scarcely explored for reinforcement applications, were investigated as the dispersed phase in polypropylene composites. Although maleic anhydride-grafted polypropylene (MAPP) is widely used as a compatibilizer in natural ...
