Abstract

Short cordage fibre, e.g. hemp or sisal, is mixed with an artificial thermo-hardening resin, dried, ground, and moulded by heat and pressure. The fibres should be 1/8 inch to 1/2 inch in length. A typical example is as follows: 700 parts of phenol-formaldehyde resole, 600 parts of chopped manila hemp, 227 parts of hexamine solution, 53 parts of methylated spirits, 24 parts of aluminium stearate, and 28 parts of nigrosine are mixed, dried at 60 DEG C. and ground. The mixture is moulded at 340 DEG C. for four minutes at 2000 lb. per sq. in. pressure.
