Definitions
- the central structural insert may comprise a thermoplastic pressing.
- the grid is composed of higher density foam than that of the blocks.
- the central structural insert may comprise a thermoplastic material.
- the thermoplastic material may be adhesively bonded or fusion welded to the first and second contoured surfaces.
- Figure 16 is a perspective view of the structural element of Figure 15;
- the structural insert 24 comprises a sheet of interwoven fibres 26.
- the fibres 26 extend in orthogonal directions (i.e. a waip direction and a weft direction). When incorporated into the structural element 2 comprising the foam body, the fibres may extend in a 0° and 90° orientation or a +45° and -45° orientation.
- Each fibre 26 may have a circular cross-section.
- Each fibre 26 is preformed so as to have a non-linear longitudinal shape, namely to have portions that are inclined to the longitudinal direction of the fibres 26, In the illustrated embodiment, each fibre 26 has a longitudinally extending truncated zig-zag configuration with opposite and alternating outer lateral sections 28, parallel to the longitudinal direction, interconnected by alternating inclined sections 30.
- the outer lateral sections 28 may optionally extend as far as the outer surfaces 12, 14 of the opposed foam bodies 8, 10,
- the shuttle apparatus 400 includes a fixed lower mould tool 402 and an upper mould tool 406 which moves between two opposed sides A and B and has a central moulding position C.
- the upper mould tool 406 has two different laterally spaced mould parts 408,410.
- the lower mould tool 402 and a first upper mould part 408 have planar moulding surfaces 412, 414 for moulding a major outer surface of a respective lower and upper foam core part 416, 418.
- the second upper mould part 410 has a contoured moulding surface 422 for moulding a structural insert 424 having surfaces 426 which are orthogonal or inclined to the width direction of the mould cavity 428 for moulding the foam core incorporating the structural insert.
- the embodiments may utilise only two top tools, for sequentially moulding the lower and upper foam bodies, but three or more top tools may be employed when additional layers are to be moulded.
- the moulded pail could be removed from a mould and placed into a new tool for subsequent over-moulding.
- it is more convenient to use a single base mould with a changing top tool machine because the foam remains hot and so it is easier to achieve each subsequent welding or fusion cycle.
- the structural inserts of embodiments of Figures 3 to 5 may be utilised in such a sequential progressive moulding method, and such embodiments also provide structural inserts with +/-45° shear enhanced structure.
- the foam cores of the embodiments of Figures 10 to 20 may be made using this variant of the progressive moulding technique.
- the progressive moulding can provide a central low density foam-containing core with high density skins, and also high density webs and/or fingers, also of foam, extending in a through thickness direction between the skins.
- the creation of a foam with a fine cell size and no defects is also important to improve the mechanical properties of the foam, in particular the strength, and to prevent excess resin absorption into the foam body to keep the final density low.
- Ultrasonic welding could be used during application of the tape to the foam surface. Such localised ultrasonic welding would prevent extended heating and consequential damage to the foam, Ultrasonic welding uses a high energy depth focused short time interval, high temperature weld. It is therefore possible to weld a high structural performance, or multi-layered, thermoplastic structural insert to the opposed foam bodies.
- Another method is a pre-preg process.
- the first low density foam body is loaded into a tool.
- a random fibre mat is placed on top to facilitate drape to the undulating surface with options for additional directional fibre placement.
- the second low density foam body is placed on top.
- the tool is closed and either consolidated or cured as before
- the preferred embodiments of the present invention provide a foam core in which, to provide particularly enhanced improvements in shear stress and sear modulus, a dual density foam core is provided, with the high density foam being configured to be aligned, particularly in the +45/-4S directions to improve shear properties.
- An 84 g/L 25mm thick foam sheet was first made by: • Foaming a continuous 0/90/45 web with 12.5mm thick walls with a even pitch in the x and y directions of 87.5mm from 117g/L PS/PPO pre-expanded bead
