| Summary: | To cope with a large number of species and difficulties in species identification
of tropical timbers, development of strength grading would be highly needed for
an efficient and effective utilisation of structural components of our tropical
timbers. To do that, an acceptable method of predicting timber strength has to
be established in order to develop the confidence in using timbers as
construction materials.
A total of 6 species of Kapur (Dryobalanops spp.) namely, Kapur bukit
(Dryobalanops beccarii Dyer), Kapur empedu (Dryoba/anops Fusca V. SI.),
Kapur kelansau (Dryobalanops oblongifolia Dyer), Kapur paji (Oryobalanops
lanceolata Burck), Kapur paya (Dryobalanops rappa Becc.) and Kapur peringgi
(Dryobalanops sumatrensis (J. F. Gmelin) Kosterm) were used in this study. The
trees selected for sampling possessed a healthy grown, straight bole and with minimum diameter of 450 mm were collected from Mixed Dipterocarp Forest and
Peat Swamp Forest. The sampling of test specimens was made throughout the
whole lengths of tree bole. |
