Noh, Izzah Azimah (2015) Standard blank for wood lamination on khaya ivorensis / Izzah Azimah Noh. [Student Project] (Unpublished)


This paper focuses on the standard blank for wood lamination on Khaya
ivorensis. Standard blank is a cutting standard for a blank which is provides
improving and increasing the value of sawn timber. Parameter for standard
blank were machining practices and lamination process. Adhesives used for
the study is Polyvinyl Acetate (PVAc). It has excellent dry adhesion, good
gap-filling properties, fast setting, and colourless glue lines and ease of
application. The purpose of standard blank based on machining practices
(system) and lamination process (process). Explain that, the different
machine used in producing sawn timber provides different result for surface
roughness that affect the gluing properties during lamination process. The
physical and mechanical properties were tested as Modulus of Rupture
(MOR), Modulus of Elasticity (MOE), Compression shear and Delamination
test were evaluated based on reference standard of in house method testing;
BS 373:2008 (MOR and MOE), BS 373:1957- reconfirm 2008 (Compression
shear) and JAS 1751 2008 (Delamination test). By using standard of variance
(SOV) of the system for MOR is 1.298, MOE is 3.571 and result for
compression shear of the system is 154.227. Meanwhile, the lamination
results for MOR is 4.099, MOE is 0.638 and for compression shear is 47.33.
Therefore, combination standard of variance for the system and lamination
for MOR is 5.32, MOE is 6.426 and 4.832. As a results for physical and
mechanical properties stated the MOE for lamination is significant compared
to with sanding and without sanding system which is no significant
differentiation at 95% confident of interval. For the compression shear, the
results show system is highly significant compared to the lamination
