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/polypropylene composites: Phase compatibilization and alternative micromechanics modeling

Industrial 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 ...

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
