Type: article
Abstract: The physico-mechanical properties of five senile fruit-bearing trees, i.e., caimito (Chrysophyllum cainito), durian (Durio zibethinus), kalumpit (Terminalia microcarpa) rambutan, (Nephelium ramboutan-ake) and sampalok (Tamarindus indica) were tested using ASTM D143-52 (2014) standard, and their end-uses were determined.The samples were obtained from Laguna, Batangas and Butuan cities. Results showed that the C. cainito and T. indica had the lowest moisture content (MC) (64.7 and 55.1%, respectively) and highest relative density (RD) (0.737 and 0.747, respectively).On the other hand, N. ramboutan-ake and T. indica had the highest radial shrinkage (6.78 and 6.52%, respectively).Tamarindus indica also exhibited the highest longitudinal (2.01%) and volumetric shrinkage (16.7%).As for the mechanical properties, in green condition and at 12% MC, C. cainito had the highest modulus of rupture (MOR) (72.40 and 109.0MPa, respectively), modulus of elasticity (MOE) (9.91 and 14.20 GPa, respectively), compression perpendicular-to-grain (6.37 and 11.10 MPa, respectively), shear (7.92 and 12.40 MPa, respectively), and hardness: end (7.42 kN in green condition).Nephelium ramboutan-ake showed the highest SPL (42.40 and 56.80 MPa, respectively) and compression parallelto-grain (29.30MPa, green condition).Tamarindus indica showed the highest hardness values: side (7.20 and 11.20 kN, respectively) and toughness (59.70 and 59.70 J/spec, respectively).Based on the properties obtained, the senile fruit-bearing tree species are suitable as alternative raw materials for various end-uses.
