8-22. What are some attractive engineering properties of polymeric materials?
Polymeric materials tend to be light weight, corrosion resistant materials. They are relatively inexpensive and are readily formed into a wide variety of useful shapes.
8-108. What are hybrid composites?
Hybrid composites involve two or more different fibers in a common matrix.
8-34. How might electrical conductivity be imparted to a plastic?
Electrical conductivity is typically imparted to plastics by filling insulating base polymers with conductive additives.
8-58. What are some outstanding physical properties of ceramic materials?
8-63. How does one produce tempered glass?
Tempered glass uses rapid cooling of the surfaces to induce residual surface compression. The surfaces cool, contract, and harden. As the center then cools and tries to contract, it compresses or squeezes the surface.
8-84. What is a composite material?
A composite material is a nonuniform solid consisting of two or more different materials that are mechanically or metallurgically bonded together.
