Fabrication of Cork Fiber with Nano Strontium Titanate by Twin Screw Extruder

Research aims on natural fibers using nano materials according to health studies. In this research, cork powder was used as a raw natural and ecofriendly material which was doped with nano strontium titanate. The composite was extruded by twin screw extruder to obtain composite fibers. The strength of the composites produced was investigated and the results revealed that all samples containing cork with nano particles have better strength, which can be used in textile industry. On the other hand, the composite UV protection was studied and the result showed the final composite has excellent protection against UV transmission which is so important in today's world. Also, water uptake was investigated and the SEM images proved the distribution of nano particles and cavity forms of cork after extrusion.
