PROBLEM TO BE SOLVED: To provide a fiber composite having low dielectric constant and dielectric dissipation factor (dielectric loss) and excellent tensile strength, tensile modulus and elongation in good balance and to provide a method for producing the fiber composite. SOLUTION: The fiber composite composed of a ring opening polymer of a bi- or multifunctional dihydrobenzoxazine compound as a matrix and a liquid crystalline polyester fiber nonwoven fabric as a reinforcing material is provided. Furthermore, the method for producing the fiber composite comprising impregnating the liquid crystalline polyester fiber nonwoven fabric with the bi- or multifunctional dihydrobenzoxazine compound and finally heating and integrating the whole under pressure is provided.
