This paper presents the moisture absorption and shock cushioning properties of flexible polyurethane foams(PU) filled with saw dust fibers at 10, 15 and 20wt%. The composites were fabricated using open molded method from a two-part liquid foams ystem consisting of part-A (Isocyanate) and part-B (Polyol).The diffusion rates from the moisture absorption test is calculated using Fick's second law equation. The sample with 10 wt% filler shows the highest diffusion rate while the lowest rateis sample with15wt% filler. The shock cushioning properties was determined via drop test where an 11.48-kg weight is dropped, from a height of 610 cm on the composites. The average G value that represents product fragility was found to be 55.45. © (2013) Trans Tech Publications, Switzerland.
