| Research Abstract |
This study deals with lowering the density of fiberboard using foam-type adhesives together with steam-injection pressing technology. Fiberboards with a density range between 0.05-0.40 g/cm^3 were manufactured with three different resins, namely, foam powder phenolic adhesive resin, polymeric isocyanate adhesive resin, and foam isocyanate resin by using steam-injection pressing and the physical and mechanical properties were examined. The results showed that the polymeric isocyanate adhesive resin was most suitable for manufacturing the low-density fiberboard and made it possible to lower the density to 0.1g/cm^3. The properties of low-density fiberboards were affected by the density, the adhesive used, and the resin content. The fiberboards showed, in general, good dimensional stability and high performances for thermal insulation and sound absorption in the density range between 0.1-0.2g/cm^3. Therefore, these could be applied to the core of composite structural materials, thermal insulation and sound absorption materials. The low-density fiberboard overlaid with the veneer of different thicknesses is now investigated targeting the development of continuous production process for 100 mm thick light-weight structural composite panel of high thermal insulation performance.
