Impact of Microstructure Defect Control of Interlaminar Toughening Particles in Prepreg on Impact Resistance of CFRP
This study focuses on the interlaminar toughening design of domestic T800 grade carbon fiber prepreg.The interlaminar microstructure and particle size of self-made thermoplastic toughening particles were com-pared with commercial thermoplastic toughening particles.Additionally,the mechanical properties of two types of particle-toughened laminates with different characteristics were compared.In this paper,an innovative quantita-tive strategy for analyzing interlayer particle microstructure defects is proposed,and the influence mechanism of in-terlayer particle microstructure defect density on the impact resistance of CFRP is discussed.
