26、 designate ply lay-up sequence for test laminates The abbreviated code to be used to designate the ply lay-up sequence of laminate test pieces shall be generated by the following rules: NOTE: the abbreviated code used to designate the ply lay-up sequence of composite components is defined in EN 3074
27、 - “Drawing annotation for composite structures“. a) The constituent plies shall be listed in sequence (left to right) starting from the chosen reference side, and the full listing enclosed in square brackets. e.g. + 45/- 451 b) Each unidirectional (tape) ply shall be represented by a number showing
28、 the orientation, in degrees, of the fibre direction with respect to the selected reference axis of the multi-ply test laminate. When the f or the 7 symbols are used with unidirectional plies, two adjacent plies are indicated, with the top sign being the first of the two. e.g. fibre axis + 45“ P * f
29、ibre axis - 45“ c) For a fabric ply, both angles subtended by the warp and the weft axes shall be indicated, and separated by a comma. However, for a fabric ply at an angle of 45“, it is normal practice to shorten to a single angle code preceded by a f or a T symbol, the top sign being the first of
30、the two. e.g. (+ 45,- 45) or (f 45) d) Fibre orientation angles shall be denoted as positive when measured in an anticlockwise direction from the reference axis as viewed from the reference side of the laminate. Angles between O“ and 90“ only shall be used, with a negative sign (together with the ac
31、ute angle) being used to indicate any obtuse angles. For all single plies at positive angles, the positive sign is normally omitted, but all negative signs shall be included. e.g. 45/- 451 e) Fabric plies shall be differentiated from unidirectional plies by inserting their ply codes in round bracket
32、s. e.g. 45/- 451 - unidirectional plies (I 45) - fabric plies STD-AECMA PREN 7000-1L-ENGL 1999 1012311 00Lb592 Lbb Page9 prEN 7000-1 I : 1999 f) Adjacent plies of differing orientation shall be separated by a slash. e.g. 45/- 451 or (k 45)/(0,90) g) Adjacent plies of the same orientation shall be in
33、dicated in abbreviated form by attaching a numerical subscript to the ply angle to denote their number. h) Specific sequences of plies which are repeated within the laminate are termed “sets”. Adjacent sets shall be indicated in abbreviated form by enclosing in square brackets and attaching a numeri
34、cal subscript to denote the number of sets. A set shall be coded in accordance with the same rules that apply to a single Ply. e.g. II(+ 4)/(0,90)141 NOTE: Square brackets are also used in rule a), but this double use is unlikely to result in any misinterpretation. i) A subscript “s” following the d
35、efinition of a laminate having an even number of plies indicates that the code for only one half of the laminate is shown, the other half being its mirror image. When the IS subscript is used for laminates having an odd number of plies, the centre ply shall be overlined, and the remaining laminate c
36、onstruction mirrored around this centre ply. e.g. (? 45)2/(0,90)s or (I 45)2/(0,90)s j) A subscript IR” (for “Reversed”) following the definition of a ply within a laminate indicates that the reference face of that ply (the reference face is that face of an assymetric ply in which the warp fibres pr
37、edominate) is further away from the laminate reference side than the non-reference face. When the reference face of the ply is closer to the laminate reference side than the non-reference face, then a subscript is not required. e.g. (I 45)/(+ 45)R/(0,90)s STD*AECMA PREM 7000-11-ENGL 2999 m LO123LL 0
