各種配向性ファイバーボードをコアにしたサンドイッチパネルの曲げ性能の解析的研究

抄録

The observed values of bending properties (MOR or MOE) for sandwich panels with veneer as the faces and various oriented fiberboards as the core were compared with the ideal values estimated by properties of veneer or various oriented fiberboards. The results showed that the bending stress was applied mainly to the face veneers, the shearing stress was applied mainly to the core fiberboards. The result in relation to the agreement between observed and calculated value was divided into the two cases. One was a rough agreement between observed and calculated value of MOR or MOE. The other was that the observed value was lower than estimated one. When shear modulus of fiberboard as the core was estimated, that of the former was larger and that of the later was smaller.
