摘要：

对落叶松木材水性高分子异氰酸酯(API)胶粘剂弦径面胶接强度进行了研究。结果表明:落叶松木材API胶粘剂弦径面胶接强度存在着差异,落叶松木材API胶粘剂径切板胶合强度试件的常态压缩剪切强度是弦切板的1.41倍,而反复煮沸压缩剪切强度径切板的却比弦切板的低。落叶松木材本身弦径面顺纹抗剪强度和剪切强度率的试验结果表明:造成落叶松胶合强度试件弦径面常态压缩剪切强度存在差异的根本原因在于落叶松木材本身弦径向的强度存在差异,木材径向的强度比弦向的大,文中对这造成这种差异的原因进行了分析

Abstract:

Bonding strength for larch(Larix gmelinii)on radial and tangential surfaces were studied in this paper. The results showed that there was significant difference in bonding strength between radial and tangential surfaces. Dry compressing shear strength of quarter-sawn board of larch was 1.41 times of flat-sawn board of larch in normal conditions, but quarter-sawn board of larch had smaller wet compressing shear strength than flat-sawn board for repeatedly boiling samples. The results of shear strength to the grain and shear strength ratio of larch showed that the difference between radial and tangential bonding strength specimens lied in wood structure of larch. That is to say, there was difference in wood strength between radial and tangential surfaces of larch, wood strength of radial surface of larch was bigger than tangential surfaces. The reasons for which quarter-sawn board of larch had smaller wet compressing shear strength than flat-sawn board of larch for repeatedly boiling samples were also analyzed.
