Durability of Structural Particleboard Evaluated by Repetitive Loading Tests

Source

A new test method was developed to evaluate the durability of particleboard (PB)—a repetitive bending test on air dried and wetted specimen. The durability of three types of PB (phenolic, urea-melamin and urea resin bonded board) was discussed by (a) number of the mechanical cycles until failure, (b) increase in deflec- tion with cycles, and (c) residual strength at various stages of mechanical cycles.

It was recognized that the effect of moisture was most critical for urea and ureamelamin board. The superiority of phenolic board came in evidence by this repetitive loading test. From the results of this fatigue test, it also was attempted to derive “degradation coefficient” for allowable stress of PB.
