摘要

Safety shoes offers protection to the foot and toes from any injuries due to impact and compression force. The toecaps of such shoes are mainly made of steel having substantial weight and are cumbersome for long-time wearing. In contrast, composite toecaps, though a little costlier, yet are lighter than steel toecaps. toecaps This paper focuses on the possible changes in the design and fabrication of the toecap by providing stiffeners on its periphery, toecap which enhances the load-bearing capacity. Such a modification of toecap can reduce the need for using higher cost composites to increase its load-bearing capacity greatly toecap. The design modification was accomplished using the software SOLIDWORKS®, ANSYS®. Chopped strand glass fiber matrix was selected as a candidate material for making the stiffener for the toecap. The material characterization was performed to identify the bonding of matrix and mechanical properties of glass fiber-reinforced composite material, which are certainly required for the numerical solution of toecaps. Finite element analysis was done for both unstiffened and stiffened toecaps under impact and compressive loading environment to compare their behaviors. The final result of numerical solution and their comparison test results showed improved load-bearing capacity of the stiffened toecaps.
