Theoretical young's modulus
Webb22 juni 2024 · Besides particles’ Young’s modulus, composites’ stiffness can be affected by an incomplete bonding of particles across their interface area with matrix . In a well-dispersed, degassed particulate composite, such debonding can be caused by stretching a composite with an insufficient particle–matrix interfacial adhesion.
