The bending properties (MORand MOE) were highly dependent on the internal bonding strength of the boards, and
all three mechanical properties were significantly impacted by the particle geometry(A) and the adhesive mass percentage (B) at a confidence level of 99% (P < 0.01),with the primary factor being the particle geometry. Some physical properties of the fiber-reinforced composites strongly depend on the fiber form factor (i.e., the length to diameter ratio), which determines the flexibility and strength of boards throughdisparate fibers (Boquillon et al. 2004).
