Paragraph starter
Research indicates that carbon fiber-reinforced composites offer superior vibrational performance compared to glass and natural fiber composites. For instance, a study by Brischetto (2017) using a three-dimensional shell model found that carbon fiber composites exhibited significantly higher natural frequencies, suggesting greater stiffness and resistance to dynamic loads. While linoleum fiber composites performed comparably to glass fiber composites in vibration analysis, carbon fiber remains the material of choice for applications demanding maximum vibration dampening and structural integrity.
