PROBLEM TO BE SOLVED: To provide a fiber-reinforced thermoplastic resin composite which exhibits a sufficient adhesion between reinforcing fibers and a matrix resin, hence having excellent mechanical strengths, and can be recycled as it is without separating the reinforcing fibers therefrom. SOLUTION: In this fiber-reinforced composite at least comprising reinforcing fibers and a matrix resin, the reinforcing fibers and the matrix resin are formed from different polypropylene resins; and the m.p., Tm(F), of a polypropylene resin for the reinforcing fibers and the m.p., Tm(M), of a polypropylene resin for the matrix resin satisfy the relation represented by the formula: Tm(F)-Tm(M)>10 deg.C. |
