ABSTRACT:
Reinforcing fibres made from polyolefin and polyolefin derivatives, the fibres having a thickness of 10-100 .mu.m and containing inorganic particles of a size of 1-10 .mu.m in an amount of at least 12% by weight, calculated on the total fibre weight, the particles being embedded in the polyolefin or polyolefin derivative, substantially none of the particles being exposed at fibre surfaces. The inorganic particles are preferably chalk or barium sulphate. The fibres are prepared from a fibrillated, stretched, blown or cast film, which may have been subjected to a surface treatment such as a corona treatment or application of avivage. The reinforcing fibers are useful in composite materials comprising an inorganic binder such as cement and puzzolane.
