Syamani FA, Subiyanto B, Massijaya MY - Insects (2011)

Bottom Line: Evaluation was in the laboratory according to the JWPA Standard-TW-S.1-1992.To improve mechanical properties of fiberboards made from sisal fibers, the boards were overlaid by rubber veneer, betung bamboo matting or formica.Result showed that the formica-overlaid sisal fiberboards performed better than other overlaid fiberboards against C. gestroi.

ABSTRACT
A study was carried out to test sisal (Agave sisalana Perrine) fiberboards properties as building materials against Asian subterranean termite, Coptotermes gestroi (Wasmann). Evaluation was in the laboratory according to the JWPA Standard-TW-S.1-1992. To improve mechanical properties of fiberboards made from sisal fibers, the boards were overlaid by rubber veneer, betung bamboo matting or formica. Result showed that the formica-overlaid sisal fiberboards performed better than other overlaid fiberboards against C. gestroi.

f1-insects-02-00462: Mean mass loss in percentage of bare sisal fiberboards at three levels of isocyanate contents.

Mentions: All samples had similar densities, showed no difference at 95% confidence level and the board mass loss was not affected. Sisal fiberboard resin contents affected the mean mass losses of bare sisal fiberboards as shown in Figure 1. Although there was no significant difference in sisal fiberboards mass losses between 10% and 12% isocyanate resin contents, 8% resin content sisal fiberboards showed different mass losses. Mean mass losses were 8.80%, 8.23% and 7.31% at 8%, 10% and 12% resin contents, respectively. The higher resin contents showed less attack by termites, possibly due to the reluctance in feeding activity of termites. One of the advantages of using isocyanate as an adhesive was to improve the durability of wood against deterioration. Visual observation showed that termites first attacked the core part of boards by making entry holes into the fiberboards. This behavior is a manisfestation of termite's characteristics that is cryptobiotic; termites tend to hide themselves and avoid the light [8]. Hardness gradients induced by manufacturing process might account for this phenomenon. Surface-layers were solidified during the hot-compression, impacting higher density than the core portion of the board.
