THICKNESS SWELL (PERCENT) 



Figure 24-9. — Effect of 5- and 8-percent resin content (RC) on average percent of 

 thickness swell of southern red oak and mockernut hickory panels (pooled data). The 

 panels were fabricated 1/2-inch thick at a target density of 52.6 Ib/cu ft with 2-1/4- 

 inch-long, 0.020-inch-thick flakes cut on four types of flakers. (Left) After ovendry- 

 vacuum-pressure-soak cycle. (Right) When cycled from 30 percent to 90 percent 

 relative humidity. (Drawing after Price and Lehmann 1978.)

COMPACTION RATIO 



Figure 24-10. — Bending strength (modulus of rupture) related to compaction ratio of 

 1/2-inch-thick sweetgum panels made from 2-1/4-inch-long, 0.020-inch-thick flakes 

 cut on four types of flakers. (Left) Tested at 50-percent relative humidity. (Right) 

 Tested after accelerated aging cycle. (Drawing after Price and Lehmann 1978.)
