Formulation design

Abstract

Different materials used in formulation designs and their basic role in any given formulation and process are enumerated in simplistic terms. Multiple dimensional fillers and reinforcements with their effect on strength and other performance and wear characteristics are explained in this chapter. Dispersion strengthening and selection of a specific design of experiments as an option are provided. An account of fractional factorial design, use of some of the critical raw material members as constituents of the design, factors that can affect frictional stability, and a good model of a design control plan have been provided for achieving good control on the quality of the BFMC design. The sequence of the design approval process with some of the critical raw material specification inputs are explained in detail with their role in the formulation design. Analytical techniques like NMR, GPC analysis as a support with their significance in the formulating materials are explained. A note on advanced BMI polymer and its usefulness in friction material formulations are explained in this chapter. Material selection and process selection sequences are given with details for a disk brake pad grouping and classification with criteria. A list providing the raw material constituents used in BFMC formulation designs given in this chapter would provide a useful input for a beginner.
