FIELD: chemistry.
SUBSTANCE: present invention relates to threads which can reinforce organic and/or inorganic materials. The threads are coated with a lubricating composition. The lubricating composition contains at least one bonding agent selected from silanes such as aminosilanes or epoxysilanes, and at least one additive capable of having an effect on the thread/matrix boundary surface(s) in order to improve fire resistance of the composite. The additive may be selected from the following: nitrates such as potassium nitrate (KNO3) and guanidine nitrate; alcohols selected from dipentaerythritol, tripentaerythritol, ethoxylated pentaerythritol, propoxylated pentaerythritol, ethoxylated/propoxylated pentaerythritol, sorbitol or derivatives thereof; phosphorus derivatives or derivatives of phosphoric acid, organophosphorus compounds, phosphates of cyclic esters, guanidine phosphate, 1,2,3-dioxaphosphorinane or ammonium pyrophosphate.
EFFECT: high fire resistance of the composite material.
