Laminate Orientation Codes, 1 This practice establishes orientation codes for 4.

Laminate Orientation Codes, 1 This practice establishes orientation codes for continuous-fiber-reinforced composite materials. A method is included for presenting s 1. Common types include unidirectional, angle-ply, cross-ply, balanced, . Orientation codes are explicitly provided for two The purpose of a laminate orientation code is to provide a simple, easily understood method of describing the lay-up of a laminate. Examples of Typical Callouts* A shorthand code for ply fiber orientations has been adapted for use in design lay-outs and studies. Thus the principal material (natural) coordinates of 4. The laminate code may also be used for filament-wound materials. 1 This practice establishes orientation codes To clearly indicate the lay-up of a laminate, it is common to use the so-called laminate orientation code , i. A balanced laminate is such that for every layer with orientation $\theta$, there exists another layer with the same material and same thickness and with an orientation -$\theta$.
