Effect of Untreated Wollastonite on Mechanical Properties of Nylon6

Abstract

Nylon-6/untreated Wollastonite composites were prepared with different loading of 15, 25 and 35 % w/w of Wollastonite (acicular ratio-15-20%) by co-rotating twin screw extruder. Mechanical properties of injection molded specimens of Nylon-6/ untreated Wollastonite composites were evaluated. Mechanical properties like flexural strength, flexural modulus, tensile strength, impact strength, hardness and abrasion resistance were evaluated for these composites. Wollastonite improves flexural modulus, flexural strength, hardness and abrasion resistance of the composites. The results suggest application of Nylon-6/Wollastonite in automotive parts, electric motors, gears, power tool housings etc. Due to fibrous nature, Wollastonite replacing short milled glass fibers for both thermoplastics & thermo-sets and short-fiber Asbestos which are hazardous to human health as well as difficult to handle.
