The pressing cycle was guided by in-house experience of
pressing fibrematerials fromannual plants. The pressing time
is one of the critical parameters for production capacity in
fibreboardmanufacture. The final fibreboard thicknesswas set
to 6mm and the pressing times were approximately 90 s, or a
press factor of 15 s/mm. The temperature of the press plate
was set to 200 ◦C. Thus the resulting maximum temperature
in the core of the fibremat during pressing was approximately
110–115 ◦C
