Title: FIBER-REINFORCED POLYPROPYLENE RESIN COMPOSITION AND MOLDED BODY OF SAME
Abstract:
Disclosed is a fiber-reinforced polypropylene resin composition which contains a propylene-based polymer (A) and reinforcing fibers (B), wherein if the content of at least one type of olefin-derived structural unit selected from among ethylene and α-olefins having 4-8 carbon atoms in the propylene-based polymer (A) is denoted by E (mass%) (the total content of the propylene-based polymer (A) and the reinforcing fibers (B) is 100 mass%) and the mesopentad fraction in the propylene-based polymer (A), as measured by 13C-NMR, is denoted by M (%), formulae (1) and (2) are satisfied, and the fiber-reinforced polypropylene resin composition can produce a molded body that exhibits excellent thermal and mechanical characteristics and exhibits excellent molded body surface appearance (especially crimped surface appearance). 85 ≤ M ≤ 99 (1) 74 ≤ M-12E ≤ 90 (2)
