摘要

The mechanical properties like tensile, pin bearing and impact properties have been studied for composites containing Fly Ash (FA) and Impact modifier (IM) in Polyvinyl Chloride (PVC) for furniture and pipe applications. Pin-bearing test is an important tool to evaluate the ability of the material to retain fasteners and the ability of the material to sustain load during the service life. The present paper evaluates the effect of variation of FA and IM on the pin bearing strength, tensile strength, modulus elongation at break and impact strength. Scanning electron microtopography indicates that the impact modifier forms a co-continuous phase at 10% of IM in PVC. Increase in void content decreases impact strength and tensile strength. As void content increases moisture absorption also increases. The results of pin bearing tests were analogous to tensile test and correlate well. Results were in accordance with impact modification theory. Moisture absorption was studied keeping in view outdoor applications.
