Cement composites reinforced by short curaua fibers [PDF]
Matéria (Rio de Janeiro), 2010 The development of an eco-friendly material that could reduce CO2 emission and that could aggregate value to a natural fiber, setting man at the countryside and raising the income of populations from poor regions is a challenge. Lignocellulosic fibers are cheap and are a readily available reinforcement, requiring only a low degree of industrialization ...

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
