Equipment for the ‘production’ or inspection of ‘composite’ structures Specially designed components and accessories to include: (a) Filament winding machines, of which the motions for positioning, wrapping and winding fibres are coordinated and programmed in three or more ‘primary servo positioning’ axes, specially designed for the manufacture of ‘composite’ structures or laminates, from ‘fibrous or filamentary materials’. (b) ‘Tape-laying machines’, of which the motions for positioning and laying tape are coordinated and programmed in five or more ‘primary servo positioning’ axes, specially designed for the manufacture of ‘composite’ airframe or missile structures. (c) Multidirectional, multidimensional weaving machines or interlacing machines, including adapters and modification kits, specially designed or modified for weaving, interlacing or braiding fibres for ‘composite’ structures. (d) Equipment specially designed or adapted for the ‘production’ of reinforcement fibres, as follows: 1. Equipment for converting polymeric fibres (such as polyacrylonitrile, rayon, pitch or polycarbosilane) into carbon fibres or silicon carbide fibres, including special equipment to strain the fibre during heating; 2. Equipment for the chemical vapor deposition of elements or compounds, on heated filamentary substrates, to manufacture silicon carbide fibres; 3. Equipment for the wet-spinning of refractory ceramics (such as aluminium oxide); 4. Equipment for converting aluminium containing precursor fibres into alumina fibres by heat treatment; 5. Equipment for producing prepregs specified in VII.A1.003, paragraph ‘d’, under ‘Materials’, by the hot melt method; 6. Non-destructive inspection equipment specially designed for ‘composite’ materials, as follows: a. X-ray tomography systems for three dimensional defect inspection; b. Numerically controlled ultrasonic testing machines of which the motions for positioning transmitters or receivers are simultaneously coordinated and programmed in four or more axes to follow the three dimensional contours of the component under inspection. Notes: 1. For the purposes of this ‘tape-laying machines’ have the ability to lay one or more ‘filament bands’ limited to widths greater than 25 mm and less than or equal to 305 mm, and to cut and restart individual ‘filament band’ courses during the laying process. 2. The technique of interlacing includes knitting.

Notes

• ‘Tape-laying machines’ of which the motions for positioning and laying tape can be co-ordinated and programmed in two or more axes, designed for the manufacture of composite airframes and missile structures;Note:For the purposes of 6.B.1.a. and 6.B.1.b., the following definitions apply:1.A ‘filament band’ is a single continuous width of fully or partially resinimpregnated tape, tow, or fibre. Fully or partially resin-impregnated ‘filament bands’ include those coated with dry powder that tacks upon heating.2.‘Fibre/tow-placement machines’ and ‘tape-laying machines’ are machines that perform similar processes that use computer-guided heads to lay one or several ‘filament bands’ onto a mold to create a part or a structure. These machines have the ability to cut and restart individual ‘filament band’ courses during the laying process.3.‘Fibre/tow-placement machines’ have the ability to place one or more ‘filament bands’ having widths less than or equal to 25,4 mm. This refers to the minimum width of material the machine can place, regardless of the upper capability of the machine.4.‘Tape-laying machines’ have the ability to place one or more ‘filament bands’ having widths less than or equal to 304,8 mm, but cannot place ‘filaments bands’ with a width equal to or less than 25,4 mm. This refers to the minimum width of material the machine can place, regardless of the upper capability of the machine.
• Equipment designed or modified for the production of fibrous or filamentary materials as follows:1. Equipment for converting polymeric fibres (such as polyacrylonitrile, rayon, or polycarbosilane) including special provision to strain the fibre during heating;2. Equipment for the vapour deposition of elements or compounds on heated filament substrates;3. Equipment for the wet-spinning of refractory ceramics (such as aluminium oxide);
• Equipment designed or modified for special fibre surface treatment or for producing prepregs and preforms, including rollers, tension stretchers, coating equipment, cutting equipment and clicker dies.Note:Examples of components and accessories for the machines specified in 6.B.1. are moulds, mandrels, dies, fixtures and tooling for the preform pressing, curing, casting, sintering or bonding of composite structures, laminates and manufactures thereof
• Filament winding machines or ‘fibre/tow-placement machines’, of which the motions for positioning, wrapping and winding fibres can be coordinated and programmed in three or more axes, designed to fabricate composite structures or laminates from fibrous or filamentary materials, and co-ordinating and programming controls;
