Resistance of Kapur (Dryobalanops Spp.) Laminated Wood Against Delamination

Measurement of the resistance of laminated Kapur towards delamination as an indicator of gluing performance is examined and discussed in this paper. Test samples were subjected to two different testing methods, designed to simulate similar application for outdoor exposure. The selected test methods were specified for testing of structural glulam samples. In general, results showed that Kapur had met all the specified requirements except for the vacuum pressure test. Good bonding performance from shear bond test and boiling water test may be sufficient in suggesting the suitability of Kapur for lamination. Further investigation on its vacuum pressure performance may be required for future study in assessing the suitability of the timber for other applications.
