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]
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.

Curaua/polypropylene composites: Phase compatibilization and alternative micromechanics modeling
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 ...
