Mechanical Properties of Hybrid PVA-Natural Curaua Fiber Composites. [PDF]

Materials (Basel), 2022
This work presents the experimental study of hybrid cement-based composites with polyvinyl alcohol fiber (PVA) and alkali-treated, short, natural curaua fiber. The objective of this research is to develop composites reinforced with PVA and curaua fiber to present strain-hardening behavior with average crack width control.

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 ...

Curaua fiber reinforced high-density polyethylene composites: effect of impact modifier and fiber loading [PDF]

Polímeros, 2020
Short fibers are used in thermoplastic composites to increase their tensile and flexural resistance; however, it often decreases impact resistance. Composites with short vegetal fibers are not an exception to this behavior. The purpose of this work is to

Composites of natural rubber with curaua fibers [PDF]

Polímeros
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.

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.
