Effect of Adding Multiwall Carbon Nanotubes on the Mechanical Properties of Carbon Fiber Based Polymer Composites
Abstract
The main objective of this paper was to providing simple method for adding CNTS into CF/polymer composite and also to understand the effect of multiwall carbon nanotubes (MWCNTS) additives on the elastic behaviors of textile based composites. The materials consist of three phases namely, carbon fibers fabric, Epoxy matrix and carbon nanotubes. Different weight ratio of MWCNTs was used (0% as reference, 0.5%, 1%, 1.5%, 2% and 2.5%). A set of mechanical tests as tensile test, shear Beam Test and three point bending tests were performed. A damage initiation and cracks propagation in composite specimens were controlled. The experimental results show an increase in the mechanical performance of the composite up to 2% of MWCNTS additives. However, beyond this value, the material strength shows a significant decay investigation.
