Bending strength of bonded three selected malaysian timber species (sepetir, kelat and sesendok) with polyvinyl acetate (pvac) / Nur Aini Adawiyah Abdullah Sani

An assessment of the bending strength of bonded three selected Malaysian
timber species namely Sepetir, Kelat and Sesendok using Polyvinyl Acetate
(PVAc) resin as adhesive was carried out. The three selected timber species
were obtained from UiTM Jengka Forest Reserve area in Jengka, Pahang.
The main objective of the study was to determine the suitability and
effectiveness of combining these three timber species in the hope to use
them as an alternative raw material for interior application. In this study, the
mechanical properties such as modulus of rupture (MOR) and modulus of
elasticity (MOE) were determined conforming to the American Society of
Testing and Materials (ASTM D1554) standard, 1986. The results indicated
that the integrity of the bond did not only depend on the adhesive but also the
type of timber species. Manufacturing parameters such as type of adhesive
was held constant. The results revealed that the density of the testing sample
tend to significantly improved the mechanical properties of the samples in
which increased density gives better mechanical properties. The bonding
quality of the sample has provided superior mechanical strength to the
Sesendok & Sesendok (S3S3) sample with improvements at 6418 MPa of
MOE and 51 MPa of MOR compared to Kelat & Kelat (S2S2) sample
