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

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

International Journal of Polymer Science, Volume 2023, Issue 1, 2023., 2023 Various environmental concerns motivate scientists and researchers to look out for unique new materials in science and technology. In order to address the demand for polymeric materials with partial biodegradability, the usage of lignocellulosic fibre in the polymer matrix has risen. Lignocellulosic fibres are a cheap, easily renewable resource that is

Advances in Materials Science and Engineering, Volume 2023, Issue 1, 2023., 2023 Currently, hybridizing natural fibers with synthetic fiber is considered as the best solution for reducing the environmental pollution and the cost of materials. This is due to the lower mechanical properties and high water absorption capacity problems of natural fiber reinforced composites and nonbiodegradability and high‐cost problem of synthetic ...
