<p>Material characterised in that between the thermoplastic polymer and the fibres there is a second thermoplastic polymer, different from the first and compatible therewith, promoting wetting of the fibres. …<??>The material is obtained by placing between the fibres and the thermoplastic polymer a second thermoplastic polymer promoting wetting of the fibres and chosen from low-viscosity polymers or polymers whose polarity is increased relative to the corresponding original polymers.</p> |
