Sandwich Injection Moulding and Physical Properties of Cup-Stacked Carbon Nanotube / Polypropylene and Polypropylene

Abstract

This study describes the manufacturing method and physical properties of sandwich structure tubes using cup-stacked carbon nanotube/polypropylene and polypropylene. The effectiveness of sandwich structure produced by sequential injection moulding to enhance the axial and transverse compressive properties of thermoplastics was investigated. It was shown that compressive properties of the sandwich tubes effectively improved by proportionally f f positioning rich nanotube materials to the outer layer.
