Composite Ply Orientation Defined by ASTM Standard.A new standard for how to describe the orientation of continuous-fiber reinforced composites is available from the American Society for Testing and Materials (ASTM ASTM abbr. American Society for Testing and Materials ), W. Conshohocken, Pa. Standard D 6507, "Practice for the Fiber Reinforcement Orientation Codes for Composite Materials composite material or composite, any material made from at least two discrete substances, such as concrete. Many materials are produced as composites, such as the fiberglass-reinforced plastics used for automobile bodies and boat hulls, but the ," helps users establish orientation codes for two-dimensional laminates and braids. The code may also be used for filamentwound materials. The standard describes a consistent practice for providing information on how the plies plies 1 v. Third person singular present tense of ply1. n. Plural of ply1. are stacked. Without an exact description of such ply (mathematics, data) ply - 1. Of a node in a tree, the number of branches between that node and the root. 2. Of a tree, the maximum ply of any of its nodes. orientation, designers would not know what material they have, making property data meaningless. Users now can compare and exchange information accurately. |
