High Performance of Rutile Titanium Dioxide Whiskers/Epoxy Resin Composites

Abstract:

Rutile TiO₂ whisker/epoxy resin composites were prepared by hot-pressing process method. The effects of different content of TiO₂ whiskers on the microstructure, microwave dielectric properties and flexural strength for TiO₂/epoxy resin composites were investigated. Results show that flexural strength increased firstly, which can reach the maximum value (105.53 Mpa), then decreased with the content of TiO₂ whisker (v%) increase. Moreover, the dielectric constant and dielectric loss of the TiO₂/epoxy resin composites increase with the increased of TiO₂ whisker (v%). When the content of TiO₂ whisker is 60 v%, the TiO₂ whisker/epoxy resin composites exhibit a higher permittivity (ε_r = 10.74) and relatively low dielectric loss (tanθ= 0.021).
