摘要
本研究聚焦国产T800 级碳纤维预浸料层间增韧设计,对比实验室自制热塑增韧粒子和市售热塑增韧粒子的层间微观形貌、粒子尺寸等,比较了两款性能不同粒子增韧层合板的力学性能.本文创新性提出层间粒子微结构缺陷定量化策略,并探讨了层间粒子微结构缺陷密度对CFRP抗冲击性能的影响机理.
Abstract
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.
