Paragraph starter
The mechanical performance of composite materials is significantly influenced by the characteristics of the interphase region between the filler and the matrix. Research by Karevan (2022) highlights that neglecting these interfacial effects can lead to underestimation of stiffness, underscoring the importance of considering interphase properties in material selection and design.
