Long fiber-reinforced columnar body comprising long-fiber-rein forced crystalline propylene resin composition and propeller-shaped fan made thereform

摘要

The present invention is modified propylene crystalline resin (A) modified with an organosilane compound, unsaturated carboxylic acid or acid anhydride thereof, long fiber reinforcing material (B) having an average fiber length of 3 to 30 mm and an average diameter of 3 to 21 μm To 80% by weight (based on the composition) and 3 to 20% by weight (based on the composition) of the elastomer (C), wherein the long fiber reinforcement (B) has a long fiber reinforced columnar (D) having a length substantially equal to its average fiber length. It is arranged in the direction of the major axis of)] to a long fiber reinforced columnar (D). Injection molding such long fiber reinforced columnar body can provide a propeller-type fan with low rotational creep even at high speed rotation which is hardly achievable in the case of short fiber-containing resin material.
