Fiber Reinforcement Effect of the Corn Stalk Skin

Abstract

Since the mechanical properties of the skin and the core of corn stalk are different significantly. The basal fourth internode of the corn stalk was chosen to do the compression test. The Maximum Force, the Compressive Strength, and the Modulus of Elasticity of the stalk skin and the core were obtained respectively. Then, the modulus of elasticity parallel to the direction of stalk skin fiber was calculated based on the measured data. The fiber reinforcement effect of the corn stalk skin was analyzed, combined with the mechanics of composites. Furthermore, the finite element model of corn stalk, regarded as composites, was constructed by ANSYS to simulate the compression test. The results showed that the simulation of reinforcement effect was well consistent with the value calculated by the mechanics of composite.
