Effect of Untreated Wollastonite on Mechanical Properties of Nylon6

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.

Study on Effect of Wollastonite on the Thermal Properties of Nylon-6 and Morphological Analysis

Nylon-6/Wollastonite composites were prepared with different concentration of 15, 25 and 35 % w/w of Wollastonite (acicular ratio-15-20%) by co-rotating twin screw extruder. Heat Deflection Temperature (HDT) of injection molded specimens of Nylon-6/ Wollastonite composites was evaluated; Differential Scanning Calorimetric (DSC) and Thermo Gravimetric Analysis (TGA) were studied for these composites. Scanning Electron Microscope (SEM) of tensile fractured sample was revealed uniformity of filler distribution throughout the matrix of Nylon-6/Wollastonite. Wollastonite improves Heat Deflection Temperature (HDT) of the Nylon-6/Wollastonite composites with reduction of product cost. 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.

Effect of untreated Cenosphere on Mechanical properties of Nylon-6

Untreated CS-PA 6 composites were prepared with different loading (10, 20 and 30 % w/w) of CS (5-100 µm) by co-rotating twin screw extruder. Injection molded specimens were prepared to evaluate mechanical properties of developed composites. Mechanical properties like Flexural strength, Flexural modulus, Tensile strength, Impact strength, and Hardness and Abrasion resistance were evaluated for these composites. Addition of Cenosphere improves flexural modulus, flexural strength, and hardness and abrasion resistance besides reducing cost of the final product. As Cenospheres are generated from fly ash in thermal power plant, they are environment friendly, eco-friendly and help to preserve natural virgin filler. The results suggest application of Cenosphere filled Nylon-6 in light weight automotive parts instead of glass filled Nylon-6. DOI: 10.17762/ijritcc2321-8169.15076

Evaluation of Thermal and Morphological Properties of Nylon 6/Cenosphere Composites

PA6/CS composites were prepared with different loading (10, 20 and 30 % w/w) of CS (5-100 µm) by co-rotating twin screw extruder. Injection molded specimens were prepared to evaluate thermal properties of developed composites. Thermal properties like Heat Deflection Temperature (HDT), Differential Scanning Calorimetry (DSC) and Thermo Gravimetric Analysis (TGA) were evaluated for these composites. Morphological properties were also studied for these composites. Addition of Cenosphere improves HDT of Nylon 6 besides reducing cost of the final product. SEM of fractured surface revealed the evenly distribution of Cenosphere in the matrix.
