Mechanical properties and microstructure of Fuji apple peel and pulp

The mechanical characteristics of apples are crucial to the mechanization apple production. In this study, Fuji with largest crop yield were studied by testing tensile strength, compression shear bending hardness, friction coefficient, and microstructure. obtained minimum values elastic modulus, compressive strength 5.0 ± 0.52, 2.2 0.15, 0.45 0.02, 0.062, 2.4 0.21 MPa, respectively, all located at maximum radial radius pulp. hardness decreased gradually storage time: pulp after 28 days was 0.16 0.02 MPa. static coefficients against TPU (Thermoplastic Urethane) rubber aluminum alloy materials 0.88 0.03 0.14 0.003, respectively. microstructure peel changed significantly damage. regular shape destroyed, cells deformed ruptured. changes in consistent macromechanical properties, so reliability test data could be verified.
