Abstract

Smooth, cured or semicured, three layer fibreboard panels with a content of thermosetting synthetic resin and a waterproofing agent are characterised by (1) the use of hard wood types in quantities up to 100% low value, undebarked material; (2) the cover layers having 10-25% the strength of the total panel strength, consisting of single fibres and fibre bundles, of which 65-80% are retained in the fraction >0.16 mm., and 0.75 mm. in the DIN sieve test, and contg. 10-100% more additives than the central layer; (3) the central layer having a homogeneous structure and 50-80% the strength of the total panel strength, and consisting of several layers, 55-75% of whose fibres are retained in the fraction >0.315 mm. and 1.5 mm. in the DIN sieve test; (4) the fibres in the contact faces of the cover and central layers penetrating between each other; and (5) the additives consisting of 8-20 kg. synthetic resin and 10-20 kg. waterproofing agent, e.g. paraffin wax/ton finished product.
