18、l Roll Cross Section 22iiiFOREWORDThis Standard establishes engineering practices for the definition of Composite Parts andtogether with related documentation practices in the Y14 Series will enable full composite partdefinition.When this Standard is specified as a requirement, its defined requireme
19、nts are assumed to beconsistent with the needs of the user. Therefore, each user provides appropriate applicationconsistent with the environment in which it is applied. Those who use this Standard as a require-ment for contractual purposes should keep the following facts in mind:(a) This Standard sh
20、ould be tailored to meet any specific needs. All users shall take carefulnote of the necessity of tailoring this Standard and the contents. The extent of tailoring will inlarge part be governed by drawing ownership and the logistics intent.(b) It is not the intent of this Standard to prevent individ
21、ual organizations from designingspecific drawing practices that meet their individual needs, but rather to provide common engi-neering delineation standards to aid the increasing interchange of drawing among industry,government, and other users.It is well recognized that individual companies have ma
22、ny detailed requirements for theirspecific method of operation. Consequently, the minimum requirements set forth in this Standardwill provide them flexibility in implementation.The successful creation and release of this Standard is attributed to the subcommittee membersand their respective companie

29、nnotation: dimensions, tolerances, notes, text, or sym-bols visible without any manual or externalmanipulation (ASME Y14.41).3.3 Bandband: the width of the collection of tows or prepreg tapethat a machine can lay down on the work surface.3.4 Bondbond: the adhesion of one surface to another, with orw
30、ithout the use of an adhesive as a bonding agent(MIL-HDBK-17).3.5 Braid Anglebraid angle: the acute angle measured from the axis ofbraiding (MIL-HDBK-17).3.6 Braid, Biaxialbraid, biaxial: braided fabric with two-yarn systems, onerunning in the +0 direction, the other in the 0 directionas measured fr
31、om the axis of braiding (MIL-HDBK-17).3.7 Braid, Triaxialbraid, triaxial: a biaxial braided fabric with laid-in yarnsrunning in the bias of braiding (MIL-HDBK-17).3.8 Braidingbraiding: a textile process where two or more strands,yarns, or tapes are intertwined in the bias direction toform an integra
32、ted structure (MIL-HDBK-17).3.9 Cocuredcocured: simultaneously cured and bonded to anotherprepared surface.3.10 Composite Materialcomposite material: a material made by imbedding loadcarrying fibers within an essentially homogeneous resinmatrix.ASME Y14.37-20123.11 Composite Partcomposite part: an i
33、nseparable assembly of compositematerial(s) that may include noncomposite material(s).See Fig. 3-1, illustrations (a) and (b).3.12 Corecore: an internal item of a sandwich construction towhich the sandwich faces or skins are attached.3.13 Core Ribbon Directioncore ribbon direction: an indicator that

See Fig. 3-1.(l) Manufacturing process specification.NOTE: Composite parts are highly dependent on the manufac-turing process utilized. Pro
48、cess parameters such as cure and postcure cycles, splices and darts, orientation deviation, temperatureramp rate, thermal soak cycles, vacuum, pressure, material condi-tioning, and manufacturing environment can all have significantimpact on the end product performance. Because verification ofendprod
