ABSTRACT

The physical and mechanical properties of 10 woody vines grown in Quezon, Philippines were determined to assess their suitability for different end-uses such as handles, frames, and weaving materials for various kinds of handicrafts and furniture. The tests were done to compare the properties of the 10 vines species that showed significant differences in physical and mechanical properties. For the physical properties, alagau-baging (Premna subscandens), hinggiw-puti (Melodinus cumingii), and diplay (Rhaphidophora acuminata) gave the lowest green moisture content (35.87, 39.28, and 79.99%, respectively) and smallest diameter (9.16, 7.93, and 9.64%, respectively) and longitudinal shrinkage (0.66, 1.87, and 1.22%, respectively). However, they also showed the highest relative density (0.47, 0.55, and 0.51, respectively). For mechanical properties, the tensile strength (TS) of diplay was significantly higher than other species in split (39.44 MPa) and round (41.78 MPa) forms under green conditions. On the other hand, kamagsang-pula (Agelaea trinervis) (56.34 MPa and 41.48 MPa) and alagau-baging (Premna subscandens) (32.84 MPa and 48.64 MPa) gave the highest TS in split and round forms at 18% MC each. For folding endurance (FE), singkamas-singkamasan (Mucuna reticulata) and hinggiw-tigas (Ficus trichocarpa) had the most folds in split (86 and 83, respectively) and round forms (92 and 98, respectively). The radius of curvature (RC) of sili-sili (Ampelocissus botryostachys) (71.54 mm) was the highest and no failure was observed in diplay (Rhaphidophora acuminata). Moreover, the maximum force of the prototype baskets (132.84 kgf) and trays (129.23 kgf) showed higher than baskets from the commercial species studied (51.97 and 95.35 kgf, respectively). Based on the results of the study, the 10 woody vines are suitable and could be used as alternative raw materials for handles, toys, frames, and weaving materials for handicrafts and furniture.
