Abstract
The effect of strain rate and short glass fiber loading on tensile and flexural properties of Polyamide 66 and Polytetrafluroethylene (PA66/PTFE) blend based composites was studied. Thermoplastic blend of 80 wt. % PA66 / 20 wt. % PTFE has been used as the matrix. The composite was prepared by reinforcing the matrix with different weight fraction percentage of short glass fibers (5, 10, 20 and 30 wt. %). These material systems were developed using melt mix method using twin screw extrusion technique followed by injection molding. The effect of different strain rates (5, 25 and 50 mm/min) on tensile properties was evaluated as per ASTM D630 respectively. The experimental results revealed that tensile properties of SGF reinforced PA66/PTFE composites vary as a linear function of strain rates. Increase in tensile strength was noticed because of increase in strain rate. This can be attributed to increase in strain energy of a material. The fractured surfaces were studied using Scanning Electron Microscope (SEM) images.
