codes

a systemized body of laws; a set of principles, as of ethics

composite

solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially in structural material made of plastic within fibrous material (as silicon carbide) is embedded

decision matrix

finishing

machining a surface to size with a fine feed produced in a lathe, milling machine, or grinder

forming

manufacturing

to make into a product suitable for use; to make fro raw materials by hand or by machinery; to produce according to an organized plan and with division of labor

material

mechanical proporties

metals

any of various opaque, fusable, ductile, and typically lustrous substances that are good conductors of electricity and heat

physical properties
