This study determined the physical [moisture Content (MC)], relative density (RD), volumetric shrinkage (VS)] and mechanical [bending, compression parallel to grain measured as maximum crushing strength (MCS), tensile strength (TS) and folding endurance] properties of 10 species of forest woody vines collected from Quezon Province. A modified ASTM D 143-14 procedures was followed. Diplay [Rhaphidophora acuminata Merr.] showed the most promising attributes among the vines such as lowest VS (15.17%), no bending failure, and highest RD (0.552), TS in green condition (39.44MPa in split form and 41.78MPa in round form), and MCS in green condition (15.67MPa), Alagau-baging (Premna subscandens Merr.) exhibited good attributes in most of the mechanical properties such as TS and MCS. Palus-palusan (Parabaena denudata Diels.) and singkamas-singkamasan (Mucuna reticulata Burck.), though without remarkable physical and strength properties, had good folding endurance in both split and round forms in their freshly harvested state. These four vine species can be used for furniture and handcraft making.
