In this research work, brake pad friction composite materials based on binary and ternary combinations of ceramic-organic fibres have been realized, following evaluation of braking performance parameters on Krauss friction testing machine adopting ECE R-90 regulations and PVW-32 standard test protocol. The obtained experimental performance data has been further used for the assessment of performance based ranking using hybrid AHP-TOPSIS technique. The order of relative weights or priority order of performance defining criteria as obtained by AHP is µ-Performance (µ_p) ~ Stability Coefficient (α) > % µ-Recovery > Wear (g) > % µ-Fade > DTR (°C) > Friction Fluctuations (∆µ) > Variability Coefficient (γ). The consistency verification highlights that λ_max = 8.0391, consistency index = 0.0045579, and consistency ratio (CR) = 0.00323 << 0.1 (upper bound limit for acceptance of CR). The aramid fibre 5-7.5 wt.% in combination with other fibres 25-22.5 wt.% (for binary combination) and 12.5/12.5 - 11.25/11.25 wt.% (for ternary combinations) has been found to impart the best overall performance level relative to other combos of the friction composites under investigation. The sensitivity analysis of performance defining criteria's and ranking orders of the compositions in the respective formulations gives robust/stable observations as the weights changes from ± (10-20)%. The hybrid AHP-TOPSIS technique in-conjunction-with sensitivity analysis might sever as an effective tool in the decision making whenever there are finite material alternatives and finite performance determining criteria having conflicting nature.

AHP-TOPSIS混合技术在有机陶瓷纤维增强摩擦复合材料制动性能敏感性分析中的应用

在这项研究工作中，通过在采用ECE R-90规定和PVW-32标准测试协议的Krauss摩擦试验机上评估制动性能参数，已经实现了基于陶瓷-有机纤维的二元和三元组合的刹车片摩擦复合材料。获得的实验性能数据已进一步用于使用混合AHP-TOPSIS技术评估基于性能的排名。通过AHP获得的相对权重或性能定义标准的优先顺序为µ-性能（µ _p）〜稳定性系数（α）>％µ-回收率>磨损（g）>％µ-Fade> DTR（°C） ）>摩擦波动（∆µ）>变异系数（γ）。一致性验证突出了_λmax= 8.0391，一致性指数= 0.0045579，一致性比（CR）= 0.00323 << 0.1（接受CR的上限）。已经发现5-7.5重量％的芳族聚酰胺纤维与25-22.5重量％的其他纤维（对于二元组合）和12.5 / 12.5-11.25 / 11.25重量％的（三元组合）组合具有最佳的整体性能。相对于正在研究的摩擦复合材料的其他组合的水平。当重量从±（10-20）％变化时，性能定义标准的敏感性分析和组合物中各组合物的排名顺序给出了可靠/稳定的观察结果。
