INVESTIGATION BEHAVIOR OF POLYMER GEAR MATERIAL
JOURNAL OF MECHANICS OF CONTINUA AND MATHEMATICAL SCIENCES, 2022 This work primarily focuses on the polymer matrix composite comprising Nylon 6 and Basalt fibre pooled together for the purpose of wear reduction in spur gear material. The method employed here using the Nylon 6 and Basalt fibre is employed through the Injection Moulding method, the fibres are combined in the ratio of (80:20) & (70:30).
