In order to enhance the interfacial adhesion between wood fiber and an unsaturated polyester matrix ( UPE ), acrylic acid (acrylic acid)/poly(methyl methacrylate), and (acrylic acid)/silanization ( AAS ) were used to treat the wood fibers. The mechanical properties and the impact fracture surfaces of the prepared composites were measured and characterized, and the fracture mechanism of these kinds of composites was analyzed. The results showed that the AAS composites possessed the optimum comprehensive mechanical properties. When the weight fraction of wood fiber was 16%, the flexural strength and flexural modulus of the AAS composites were increased by 28.9 and 51.8%, respectively, compared to those of untreated composites. The highest tensile strength and lowest water absorption were also noted for AAS composites. These composites possessed the strongest interfacial adhesion between wood fiber and the UPE matrix. J.
