This document provides information on composite materials from multiple sources. It discusses the matrix and dispersed phases of composites, different types including metal matrix, ceramic matrix, and polymer matrix composites. It also addresses particulate, fibrous, and laminate composites. Manufacturing processes are covered such as wet layup, resin transfer molding, and filament winding. Key factors for selecting a manufacturing process include the number of parts, material types, product size and shape. Composites offer advantages like strength and weight savings but also challenges such as manufacturing difficulties and variability.
