Polyurethane composites synthesized using natural oil-based polyols and sisal fibers
(Scrivener Publishing, 2017-09-13)
Elastomeric polyurethanes were prepared from a reference polyurethane system modified with biobased polyols synthesized using rapeseed or palm oils. The reference material was modified by replacement of the commercial ...
1-3 castor oil-based polyurethane/PZT piezoelectric composite as a possible candidate for structural health monitoring
(2020-10-26)
In this study, we obtained and characterized a piezoelectric composite with 1-3 connectivity from castor oil polyurethane (PUR) and lead zirconate titanate (PZT) rods. Two samples were obtained, one with 15% PZT volume and ...
Dielectric and pyroelectric properties of a composite of ferroelectric ceramic and polyurethane
(Springer, 2002-05-01)
Flexible piezo- and pyroelectric composite was made in the thin film form by spin coating. Lead Zirconate Titanate (PZT) ceramic powder was dispersed in a castor oil-based polyurethane (PU) matrix, providing a composite ...

Sugarcane Bagasse Fibers Reinforced in Polyurethane for Sorption of Vegetal Oil
(2020-01-01)
To enhance the removal of vegetal oil from water, the influence of the concentration of fibers from sugarcane bagasse pretreated by the steam explosion as reinforcement in polyurethane foam was used. The composites were ...
Polyurethane composite membranes
(2014-01)
Fibrous nanostructured polyurethane composite membranes were developed using electrospinning process. Membranes of polyurethane having silver and zinc oxide as additives were prepared by electrospinning of solutions having ...
Wood flour - Recycled polyol based polyurethane lightweight composites
(Sage Publications Ltd, 2009-11)
This work is focused on the production and characterization of lightweight polyurethane (PU) composites reinforced with pine wood flour (WF), which can have applications in car interior panels, construction, and acoustic ...
