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 ...
Cure Kinetic of Castor Oil-Based Polyurethane
(Wiley-Blackwell, 2011-12-05)
This research presents the kinetic studies on the cure reactions of a new material, castor oil-based polyurethane resin. Thermal analysis by isothermal differential scanning calorimetry was used, as a variety of factors ...
