PURPOSE:To obtain the composition, excellent in hardness, rigidity, impact and heat resistance, appearance and dimensional stability and useful as automotive materials, etc., by bending a polyolefin resin having a specific melting point with specified inorganic fiber and specific organic synthetic fiber. CONSTITUTION:The objective composition is obtained by kneading (A) 60-97wt.% polyolefinic resin having <=170 deg.C melting point with (B) 3-40wt.% inorganic fiber having 0.1-2mum average fiber diameter, 10-200 aspect ratio and 10-150mum average fiber length and (C) synthetic organic fiber having >=200 deg.C melting point, 0.5-100mum fiber diameter and 1-30mm fiber length in an amount of 3-30 pts.wt. based on 100 pts.wt. sum total of the components (A) and (B) at a temperature below the melting point of the component (C). Furthermore, (D) 0.01-10 pts.wt. acid-modified polyolefinic resin is preferably further contained in 100 pts.wt. objective composition. |
