Porosity, which arises during material manufacturing, significantly affects material performance and serves as a crucial quality metric in additive manufacturing. It impacts not only the mechanical attributes of the material but also its reliability and longevity. Effects of porosity on performance: – Strength reduction: Pores diminish material strength, particularly tensile and compressive strength. – Weakened rigidity: Porosity lowers material rigidity, compromising the stability and load-bearing capacity of structural parts. – Reduced durability: Porosity acts as a source of cracks, accelerating material aging and fatigue failure. – Deteriorated chemical resistance: Porosity lessens the material’s chemical resistance, shortening its lifespan in harsh environments. Mitigation strategies: Optimizing fiber arrangement: 1. Utilize advanced fiber […]

The application of carbon fiber in running shoes can be attributed to several of its advantageous properties. Research indicates that 85% of sprinters using shoes with a higher degree of longitudinal bending stiffness within a specific range have noticed some level of enhanced athletic performance. An increase in this stiffness can particularly benefit the initial 10-meter acceleration phase of sprinting and can effectively lower oxygen consumption during jumping and directional changes. Furthermore, adjusting the longitudinal bending stiffness of running shoes can influence running biomechanical parameters, consequently affecting running performance and economy. The enhanced stiffness can shift the ground reaction force during the running support phase forward, thereby extending the force
