3 TERMS AND DEFINITIONS
The following terms are defined as their use applies in this Standard.
3.1 Adhesive
adhesive: a substance apable of holding two materials together by surface attachment (CMH-17).
3.2 Annotated Model
annotated model: a combination of model, annotation, and attributes that describe a product (ASME Y14.41). .
3.3 Annotation
annotation: dimensions, tolerances, notes, text, or symbols visible without any manual or external manipulation (ASMEY14.41).
3.4 Attribute
attribute: a dimension, tolerance, note, text, or symbol required to complete the product definition or feature of the product that is not visible but available upon interrogation of the annotated model (ASME Y14.41).
3.5 Band
band: the width of the collection of tows or tape that a machine can lay down on the work surface.
3.6 Bond
bond: the adhesion of one surface to another, with or without the use of an adhesive as a bonding agent (CMH-17).
3.7 Braid, Biaxial
braid, biaxial: braided fabric with two-yarn systems, one running in the +0 direction, the other in the -0 direction as measured from the axis of braiding (CMH-17).
3.8 Braid, Triaxial
braid, triaxial: a biaxial braided fabric with laid-in yarns running in the bias of braiding (CMH-17). .
3.9 Braid Angle
braid angle: the acute angle measured from the axis of braiding (CMH-17).
3.10 Braiding
braiding: a textile process where two or more strands, yarns, or tapes are intertwined in the bias direction to form an
integrated structure (CMH-17).
3.11 Composite Material
composite material: a material made by embedding load carrying fibers within an essentially homogeneous resin matrix.
3.12 Composite Part
composite part: an inseparable assembly of composite material(s) that may include non-composite material(s). SeeFigures 3-1 through 3-3.
3.13 Core
core: a component used to separate structural laminates (e.g, face sheets, skins, sandwich faces) that are bonded to it.
3.14 Core Ribbon Direction
core ribbon direction: an indicator that shows the direction of maximum shear strength and rigidity along the continuous webs of material.
3.15 Cure
cure: to change the properties of a thermosetting resin irreversibly by chemical reaction. Cure may be accomplished by addition of curing agents, with or without catalyst, and with or without heat and pressure (CMH-17).
3.16 End ltem
end item: an item, such as an individual part or assembly, in its final or completed state (ASME Y14.24).
3.17 Fabric, Nonwoven
fabric, nonwoven: textile structure produced by bonding or interlocking of fibers, or both, accomplished by mechanical, chemial, thermal, or solvent means, and combinations thereof (CMH-17).
3.18 Fabric, Woven
fabric, woven: a generic material construction consisting of interlaced yarn or fibers, usually a planar structure. Specifically, cloth woven in an established weave pattern from advanced fiber yarns and used as the fibrous constituent in anadvanced composite ply.
3.19 Fiber Orientation Array
fiber orientation array: an array of discrete locations on the laminate reference surface used to define the primary(e.g.0°)and/or secondary (e.g.. 90°) fiber orientation directions.
3.20 Filament Winding
filament winding: a reinforced-plastics process that employs a series of continuous, resin-impregnated fibers applied to amandrel in a predetermined geometrical relationship under controlled tension.
3.21 Helical (Helix) Ply
helical (helix) ply: two windings, one for each of the plus/minus orientations.ASME Y14.37 pdf download.
