Fabric composite assemblies

In the past decade, controlled synthesis of ceria based nanomaterials, such as obtaining the pure phase, doping for desirable composition, controlling uniform size, shape, and nanostructure, tuning surfaces, fabricating composites, assemblies and mesostructures, have been the targets of active research since ceria-based materials exhibits unique properties when their sizes are reduced to nanometer scale.

The manufacturing features a novel automated fabric laminating system for the one-piece skin and spar components. For ease of construction, the in situ resin infusion technique and the curing of the composite assembly is undertaken in a factory, ideally located at the dockside where the fabrication of the machine is being assembled. 

Examples of the use of blocked diisocyanates for rubber-fabric adhesion are as follows vulcanized polychloroprene and SBR can be adhered strongly to nylon and polyester fibre fabric by means of aqueous adhesive systems (Table 8.4). This combination is spread or roller coated on to the fabric which is then allowed to dry. Bonds to sheet rubber stock can be made immediately after the treated fabric is dried or at any time thereafter. When the sheet rubber is applied it should be held under moderate pressure to provide intimate contact with the treated fabric and to prevent lifting if any gases are emitted during cure. Press cures of 20-40 min at 140°C are sufficient to cure the adhesive and most elastomer compositions being adhered. If a latex film is applied to the treated fabric, the assembly can be cured in a hot-air oven at 120"C. A chemical bond results between fabric and the diphenylmethane-/7,/ -diisocyanate generated on the thermal cleavage of the blocked diisocyanate. 

The composition of an alloy alone does not ensure the quality of the product. Evaluation of resistance to corrosion in a given environment, adverse effects of corrosion products on utility or contents, susceptibility to a specific type of corrosion and fouling, and tendency to corrosion failure due to fabrication and assembly processes, such as welding, forming, machining, heat treatment, etc., are of prime importance for the selection of material.
