In the development of bayesite, a new fibreboard,
experiments were conducted to obtain some insight into the nature of
the relationship of its permeability to the mix of its four ingredientsrll{
A: short fibres,
B: medium fibres,
C: long fibres,
D: binder,
}
and the pressure of which these are bonded. The results of 21
such experiments are reported. It is required to investigate the
dependence of permeability of mixture and bonding pressure.
All 4-part compositions sum to one.
