20100125112 | Natural Fiber-Reinforced Polylactic Acid Resin Composition and Molded Product Made Using the Same - Disclosed is a natural fiber-reinforced polylactic acid resin composition that includes (A) a first polylactic acid resin; and (B) a natural fiber surface-treated with a second polylactic acid resin. The second polylactic acid resin can include a different isomer from the first polylactic acid resin, or alternatively, when measured under isothermal conditions after quenching from about 240° C. to a crystallization temperature, a spherulite crystal is first formed at a surface of the natural fiber and the growth rate at the surface is faster than at other positions. A molded product made using the natural fiber-reinforced polylactic acid resin composition is also disclosed. | 05-20-2010 |
