Taking thermoplastic dialdehyde starch as the matrix, pineapple leaf fiber as the reinforcing material, the pineapple leaf fiber/thermoplastic starch composite was prepared by hot pressing. The effects of the fillings of pineapple leaf fiber on the mechanical, physicochemical and degradation properties of the composite were studied. The results show that when the fillings of pineapple leaf fiber is 15%, the tensile properties of the composite is the best, and the tensile strength and elongation at break are 7.4 MPa and 1.25%. The flexural strength and flexural modulus were 13.18 MPa and 2 245.54 MPa respectively when the fillings of pineapple leaf fiber was 20%.With the increase of fiber filling, the density of composite gradually decreases, moisture content and degradation rate of the composite gradually increased.
