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

open access: yesPolímeros, 2016
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

Hemicellulose Removal in Curaua (Ananas erectifolius) Fibers for Polyester Composites

open access: yesNova Scientia, 2018
Introduction: Alkaline treatments extract hemicellulose from the fibers, which can be reused in the manufacture of other materials, and the cellulosic portion can be applied as reinforcement in a composite.

Study of the dynamic fragility of polymer nanocomposites: Correlation with damping

open access: yesPolymer Composites, Volume 44, Issue 9, Page 5619-5632, September 2023., 2023
The dynamic fragility and activation energy were calculated and analyzed on the basis of the dynamic mechanical data of a series of polymer nanocomposites. A general trend of a decreasing dynamic fragility with increasing Tg was found. No monotonic effect of the nanofiller loading on the fragility was detected. Abstract In this work, an extensive study

Mechanical and thermal properties of recycled polyethylene/surface treated hemp fiber bio‐composites

open access: yesPolymer Composites, Volume 44, Issue 8, Page 4976-4992, August 2023., 2023
This study presents the production of economic, mechanically, and thermally stable polymer composites via their sustainable and reusable components with an environmentally friendly approach. Abstract Hemp is a good option for polyethylene additives because of its high cellulose and fibrous content. This study aims to modify natural hemp fibers with the

Recent trends in nanocomposite packaging films utilising waste generated biopolymers: Industrial symbiosis and its implication in sustainability

open access: yesIET Nanobiotechnology, Volume 17, Issue 3, Page 127-153, May 2023., 2023
Utilisation of residual biomass could act as green and sustainable approach to lessen the waste burden on Earth and fulfiling the demand for bio‐based goods. Using waste as a raw material through industrial symbiosis should be taken into account as one of the strategies to achieve more economic and environmental value through inter‐firm collaboration ...

Processing, thermal and mechanical properties of composite laminates with natural fibers prepregs

open access: yesPolymers and Polymer Composites, 2022
This work manufactured prepregs by impregnating discontinuous curaua fibers with B-stage epoxy resin. The prepreg layers were then stacked to produce laminates by hot compression.
