Abstract: In recent years, as a mounting number of attention has been paid to green environmental protection and sustainable development, the natural fiber material has become a heated topic in research. Palm fiber/natural latex (PF/NL) composite mattress was prepared by production process of mattress, with the palm fibers (PF) as reinforcement and natural latex (NL) as matrix. Based on this process, this paper proposed a hypothesis that the PF/NL composite mattress had transverse isotropic. By designing three different mechanical experiments, five different material parameters of the PF/NL composite mattress could be measured. After that, we could establish the stiffness matrix of the PF/NL composite mattress and constitutive equation. On this basis, the finite element model built by the finite element software was used to verify the experimental results. The conclusion is that transverse isotropic model has high accuracy and credibility for the simulation of PF/NL composite mattress.
