Abstract:

Fifteen kinds of young plantation wood, commonly used for hardware tool handle from Yongkang in central Zhejiang Province, were used to compare and comprehensive evaluate physical and mechanical properties. The result showed each timber trait was significantly different among tree species. The difference of full-dry density was most than that of other physical properties. The oven-dry density of Sapindus mukorossi was 1.99 times higher than that of Alniphyllum fortunei . Species with better dimensional stability were Michelia chapensis, Schima superba, Pterocarya stenoptera and Cyclobalanopsis glauca. Toughness of all tested wood was above middle, with that of Camptotheca acuminata, Ligustrum lucidum and Ilex micrococca were higher than the average of domestic broad-leaved wood. And hardness of most tested wood was above middle, but compressive strength parallel to grain, bending strength, modulus of elasticity were low. Processing applicability of fifteen young tree species were comprehensive evaluated by coordinate synthesis method. The result showed that wood processing adaptability of Sapindus mukorossi, Schima superba and Cyclobalanopsis glauca were the best, that of Ligustrum lucidum, Koelreuteria bipinnata var . integrifoliola, Liquidambar formosana, Ilex micrococca and Platanus orientalis were the second, and that of Camptotheca acuminata, Liriodendron chinense and other five tree species dropped to the worst in turn.
