Preparation Method of High Resilience Nonslip Basketball Sole Composite Material

Abstract

Today, with the gradual improvement of material living standards, basketball is becoming more and more popular, and the pursuit of sports protection and shoes performance is also getting higher and higher. A good pair of basketball shoe soles can help athletes solve these problems. This article is aimed at studying the preparation of basketball shoe soles made of high resilience and nonslip composite materials. Under this research topic, this paper proposes a method for the design of shoe sole antislip pattern and the measurement method of composite material’s resilience performance and a 3D printing method based on FDM technology to print the shoe sole. At the same time, an experiment was designed to explore the high resilience and antislip performance of the sole. And the stability of printing technology is analyzed to ensure the quality of sneaker printing. The experimental results in this article show that the antislip performance of the sole printed by the above method design has been improved by 31%, and the rebound capacity has been improved by 44%. At the same time, the rebound time is significantly shorter than that of several common basketball shoes on the market.

Physical Property of 3D-Printed N-Pointed Star-Shaped Outsole Prepared by FDM 3D Printer Using the Lightweight TPU

“…In shoe design, traction was considered an important feature, while the design of the outsole pattern and the selection of the materials control the traction levels, contributing to the safety of footwear. Footwear manufacturers intend to improve the outsole hardness in order to reduce wearing abrasion over time, whereas it might reduce the slip resistance and raise the potential of slip and fall injury risk [ 19 ]. As shown in Figure 3 , there was a propensity for the static and dynamic coefficient of friction for outsoles with various pattern designs to climb as the thickness of LW outsoles increased, increasing in order LW 3-PS > 4-PS > 6-PS specimens in all thicknesses.…”

“…The resilience of the outsole has an important impact on the health and comfort of the foot due to the biomechanical change of the sole caused by the resilience of TPU materials being subject-dependent [ 18 , 19 ]. The material density and melting point determine the resilience properties [ 20 ].…”

“…The physical properties, such as density [ 11 , 12 ], static compression [ 13 ], static/dynamic features of friction [ 14 ], abrasion [ 15 , 16 ], resilience [ 17 , 18 , 19 ], surface force, and plantal pressure [ 20 , 21 ], which mainly derive from the design geometry and material, offer comfort, safety, and effective gait to the foot. The outsole is the outmost part of the shoe, also known as the sole, the part directly in contact with the playground or floor surface; it is one of the basic footwear components and plays a role as a buffer layer of material between feet and ground, offering cushion and comfort to the feet of the end-user through shock absorbance [ 22 , 23 , 24 ].…”
