Paragraph starter
The research by Yang et al. (2019) demonstrates that incorporating random vibration during the curing of carbon/epoxy composites significantly enhances interlaminar shear strength by reducing void content. This suggests that actively influencing the curing process through mechanical means can lead to improved material integrity and performance, a critical consideration for the development of robust composite structures.
