Definitions
- This invention relates to a method of manufacturing structural elements.
- the invention resides in a structural member comprising: a least one syntactic foam sandwich panel; the sandwich panel having a syntactic foam core and at least one skin; and at least one reinforcement element attached to the sandwich panel.
- the syntactic foam core may include microspheres made from polymeric materials such epoxy resin, unsaturated polyester resin, silicone resin, phenolics, polyvinyl alcohol, polyvinyl chloride, polypropylene, and polystyrene or from inorganic materials such as glass, silica-alumina ceramics or Cenospheres (hollow fly ash particles)
- the skins of the syntactic foam sandwich panels may be made from fibre reinforced polymers.
- the fibres may be made from glass, carbon,
- the polymer may be made of polyester, vinylester, epoxy, polyurethane, thermoplastics or combination thereof.
- the polymer used in the skins is the same as that used in the syntactic foam. More preferably the syntactic foam sandwich panel is produced in single manufacturing process, in this way a strong primary bond can be created between the skins and the syntactic foam core.
- the reinforcement elements may be made from steel, concrete, timber, fibre reinforced polymers or any other material.
- An adhesive is typically used to adhere the syntactic foam sandwich panels to the reinforcement elements.
- the fibres may be made from glass, carbon, Kevlar, thermoplastic or combinations thereof and the polymer may be made of polyester, vinylester, epoxy, polyurethane, thermoplastic resins or combinations thereof.
- One or more tie elements may span across the adhesive in order to avoid delamination of the adhesive and provide the assembly with robustness.
- the tie elements may be made from steel, concrete, timber, fibre reinforced polymers or any other material.
- the tie elements might also act as a reinforcement element.
- the structural elements may include bulkheads, diaphragms, strong points and/or internal ties.
- the invention resides in a method of producing an improved structural element, said method including the steps of: obtaining at least one syntactic foam sandwich panel; obtaining at least one reinforcement element; and joining the at least one syntactic foam sandwich panel and reinforcement element to form the improved structural element.

- the sandwich panel has a syntactic foam core 11 and two fibre reinforced polymer skins 12.
- the syntactic foam core in this embodiment is made from epoxy resin with Cenospheres and expanded polystyrene bead fillers. It should be appreciated that the materials used to produce the syntactic foam core may be varied to specified need of a structural element.

- the beam 40 is manufactured by applying adhesive to the two fibre reinforced polymer U-shape sections 41 and placing the two fibre reinforced polymer U-shape sections 41 over respective ends of the sandwich panel. Due to the shape of the fibre reinforced polymer U-shape sections 41 , the contact area between the reinforcement modules and the syntactic foam panel 10 is significantly increased compared to the fibre reinforced polymer reinforcement strips 31 in FIG 3. This results in significantly increased resistance against delamination of the two fibre reinforced polymer U-shape sections 41 from the sandwich panel 10.
