Abstract
A process for the production of fibre-reinforced sheet material in indefinite lengths comprises a first rolling step wherein a curable dough of thermoplastic polymer containing reinforcing fibres is rolled onto one face of a band to form a first coating which is dried prior to a second rolling step wherein further dough is rolled onto the first coating to form with the first coating a single layer; said single layer is dried, stripped from the band and cured. The dough includes a special solvent system comprising a solvent for the polymer and a non-solvent liquid, to give the dough a 'release' characteristic.
