(Practice)Standard Practice for Fiber Reinforcement Orientation Codes for Composite Materials
Standard Practice for Fiber Reinforcement Orientation Codes for Composite Materials
SIGNIFICANCE AND USE
4.1 The purpose of a laminate orientation code is to provide a simple, easily understood method of describing the lay-up of a laminate. The laminate orientation code is based largely on a combination of industry practice and the codes used in the NASA/DOD Advanced Composites Design Guide,5 CMH-17-2G, and ISO 1268-1.
4.2 The braiding orientation code provides similar information for a two-dimensional braid, based largely on Standard Test Methods for Textile Composites.6
SCOPE
1.1 This practice establishes orientation codes for continuous-fiber-reinforced composite materials. Orientation codes are explicitly provided for two-dimensional laminates and braids. The laminate code may also be used for filament-wound materials. A method is included for presenting subscript information in computerized formats that do not permit subscript notation.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5. Reference SystemSystems
5.1 A reference set of reference coordinate axes and associated reference plane and direction are selected before writing the
orientation code. The reference plane is selected as the bottom or top layer for the laminate orientation code. For laminates
symmetric about their midplane, the orientation code using the top layer as the reference plane is identical to the orientation code
using the bottom layer as the reference plane; selection of the reference plane effectively determines the positive z- or three-axis
of the lamin
