Definitions
- the present invention relates in its various aspects to a moulding tool, a tool set, a method of manufacturing a moulding tool, and a method of manufacturing a part such as a composite part.
- US 5902535 describes an inner mould line (IML) tool for resin film infusion moulding a component in a single-step moulding operation.
- the IML tool comprises a plurality of mandrels in a modular design.
- the mandrels may be individually assembled over a preform assembly, such that the surface configurations on the underside of the mandrels match with the stringers and intercostals of the preform assembly.
- a further aspect of the invention provides a tool set comprising:
- a second mandrel configured to fit into the mandrel recess and form a second component which has a different shape or size to the first component.
- the tool can be used in a modular tool set, in which a variety of mandrels can be interchangeably fitted into the mandrel recess(es) to form a desired component.
- moulding tool can accommodate mandrels for stringers and also for additional components such as rib feet, spars and/or rib posts.
- a further aspect of the invention provides a method of manufacturing a part, the method comprising:
- the panel may be a variety of elements, depending on the application.
- the panel is either a wing skin or part of a capping layer which is wrapped around the moulding tool.
- the method further comprises:
- a further aspect of the invention provides a method of manufacturing a part, the method comprising:
- the layer is formed by wrapping around the or each inner mould line tool.
- the or each inner mould line tool is rotated as the layer is wrapped around the inner mould line tool(s), for instance by a filament winding machine.
- FIG. 7 shows the upper and lower Outer Mould Line (OML) used in the assembly of Figure 6;
- a flexible surface covering (such as a laminate of pre-cured plies) may be bonded or bolted to the upper moulding surface before the mandrel recesses have been formed.
- the flexible surface covering can then be machined to form a desired moulding profile, and punched through to form the tool and mandrel locating holes.
- Figures 5 to 1 1 illustrate a process for manufacturing a full wing-box composite part.
- rib foot channels 51 Only the upper rib foot channels 51 are shown in Figure 5, but similar rib channels are formed in the hidden lower moulding surface. Islands 58 are located between the channels. Rib post recesses 57 are formed in the leading and trailing moulding surfaces in line with the rib foot channels 51. Only two rib post recesses 57 are shown in Figure 5, but a third rib post recess may be provided in line with the rib foot channel 51 at the far end of the tool. Flats are formed in the lower moulding surface in the desired positions of manholes in the finished wing box. Only a single flat 56 at the root end of the IML tool is shown in Figure 5, but a number of such flats are positioned along the length of the hidden lower moulding surface.
- Stringers, rib feet and spar caps are formed in a similar manner to the stringers, rib feet and spar caps shown in Figure 3, and fitted in place in their respective recesses on the IML tool 50.
- Rib posts (not shown) are also moulded onto back-to-back tools similar to the tool stringer tool 10 shown in Figure 3, and the tools are fitted into the rib post recesses 57.
- the capping layer 58 comprises a series of capping plies.
- the fibres in most of the capping plies are likely to run at an angle of approximately 90° to the spanwise direction of the tool (that is, the axis of rotation of the tool). However, angles of up to 45° may be achieved by moving the spool of the filament winding machine at an angle to the shaft as the spool unwinds.
- the MLG IML tool 51 and Pylon IML tool 52 are then positioned in place as shown in Figure 6.
- the MLG IML tool 51 is shown in detail in Figure 8.
- the tool 51 is symmetrical about its centre line, so only the upper half will be described in detail.
- the upper half comprises an upper caul plate with an upper face 60 which engages the upper skin 59 and a side face 64 which engages the capping layer 58.
- the side face 64 extends into a flange with a pilot hole 61.
- a pin 62 has a nut 63 threaded onto its distal end (not shown). The nut 63 engages the nut carried by the lower caul plate, and one or both of the nuts can be rotated to adjust the spacing between the caul plates, thus ensuring accurate thickness for the upper and lower skins 57,59.
- the tool 51 may extend along the length of the tool 50, or may be located in line with the landing gear pad-up recess 52.
- the tool 50 has a pilot hole 65 aligned with the pilot hole
- the OML tools are then removed, and the IML tools removed from the larger root end of the full wing-box part. Manholes and any other critical areas are then machined to provide a part ready for assembly.
- rib webs are passed through the root end of the wing-box and bolted to the rib posts and rib feet. Some additional bolting of the spar caps to the skins 57,59 may be required in areas of high shear.
- FIGs 11-16 illustrate an alternative process for manufacturing a half wing-box composite part. The process is similar to the process shown in Figures 1-4, and only the differences will be described in detail.
- An IML tool 100 shown in Figure 13 is formed from a billet 101 shown in Figure 11 which is first machined to form the inner mould line surface, spar channels and pad-up recesses as shown in Figure 12, and then machined to form the stringer and rib foot recesses as shown in Figure 13.
- the tool 100 receives the same mandrels as the tool 1, and these are shown individually in Figure 13 prior to insertion into their respective mandrel recesses.
- Figure 14 shows the mandrels and preforms in place, and
- Figure 15 shows a capping layer 102 which is then draped onto the tool.
- Caul plates 103 ,104 are then fitted to the leading and trailing edges as shown in Figure 16.
- a skin 105 is laid onto an OML tool 106.
- the tool 100 is placed onto the skin 105 as shown in Figure 18, and dowel pins extending from a plate 111 are inserted into holes in the OML tool and caul plates to accurately position the parts.
- Four of the dowel pins 107-110 are shown in Figure 18, the other dowel pins being hidden.
- the assembly of Figure 18 is then bagged, and cured in an autoclave.
- Figures 19-22 illustrate an alternative process for manufacturing a full wing-box composite part.
- a pair of IML tools 120,121 similar to the IML tool 100 are fitted with preforms as shown in Figure 21.
