Figure 24-43. — Effect of flake length and thickness in faces and cores and panel density 

 (ovendry weight and volume at 50-percent RH) on linear expansion of southern hard- 

 wood flakeboard during the ovendry-vacuum-pressure-soak test (top) and cycling 

 from 30- to 90-percent relative humidity (bottom). See table 24-21 (footnote^) for 

 species mix and fabrication procedure. (Data from Price and Hse, text footnote'.)
