摘要

以不同角度刀具切制杨木刨片,并制成大片刨花板,对刨片的流变和强度性能及刨花板性能进行了测定和研究。主要结果是:（1）采用较大前角刀具所切出的刨片的流变和强度性能较好,刨花板平面抗拉强度有显著提高,抗弯强度亦有改善;（2）微斜面可在不显著影响刨片和刨花板性能的条件下增强刀刃,为进一步采用更大的前角提供了可能性。

Abstract

Poplar wood was cut into flakes with which flakeboards then were made and board properties were determined. The main results obtained were: 1) The larger the rake angle the better the rheological and strength properties of the flakes and that of the flakeboards; 2) It was found possible to strengthen knife edge by means of a microbevel so that larger rake angle can be used without being harmful to board properties and too much increasing cutting resistance.
