522 Chapter 19 Plastics and Composite Materials: Forming and Shaping

The design of plastic parts must take into account their low strength and stiffness
and their physical properties, such as high thermal expansion and generally low
resistance to temperature. Inspection techniques are available to determine the in-
tegrity of these products.
Because of their expanding use in critical applications, the processing of metal-
matrix and ceramic-matrix composites has undergone important developments to
ensure product integrity and reduce costs. Metal-matrix composites are processed
by liquid-phase, solid-phase, and two-phase processes. Ceramic-matrix compos-
ites can be processed by slurry infiltration, chemical synthesis, or chemical-vapor
infiltration.
Because of the wide variety of low-cost materials and manufacturing techniques
available, the economics of processing plastics and composite materials is an im-
portant consideration, particularly when compared with that of metal compo-
nents. The relevant factors include machinery and die costs, cycle times, and
production rate and volume.
