Proces for treating fibers for use in composite materials like asphalt and concrete, and composite material thus obtained

摘要

A component has reinforcing fibres encapsulated in a material that is solid at ambient temperature and inert to the fibres. The fibres extend along part of the component. Independent claims are included for the following: (a) Forming a component as above by heating a mixture of the fibres and encapsulating material so it melts. The mixture is made homogeneous, allowed to become semi-solid and broken into discrete components. (b) Equipment for performing (a). (c) A composite material made from the above component. Preferred Features: The mixture is heated and homogenised in an extruder and the extrudate broken up in a granulator. The fibres are recycled material ≥ 10 mm and preferably ≥ 15 mm long.
