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

Modification of Brazilian Curaua Fibre Properties
, 2021 Natural fibres extracted from plant bast and other parts are talented resources to the engineering polymers. Especially plant fibres extracted from amazon base are precious with cellulosic resulting stronger to bear mechanical loading. However vegetable fibres are naturally coated with wax and other deposits to protect from environmental attacks and ...

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