主講人 : ?？得?教授

Over the past 50 years, advanced Carbon Fiber Reinforced Polymer (CFRP) composites have become central to large commercial aircraft structures. This paper reviews compressive strength  d on the latest data and results from Toray and provides a comprehensive theoretical investigation into predicting CFRP compressive performance, with a focus on kinking band formation mechanisms.

The findings highlight that the compressive strength of high-performance CFRP composites is primarily determined by the stiffness and toughness of the resin assuming the elimination of bonding defects and fiber misalignments. To advance CFRP materials, enhancing the resin's nonlinear shear modulus should be prioritized. This is especially significant for China’s C919 and C929 projects, which aim to replace imported CFRP with domestically sourced materials, advancing self-reliance in aerospace manufacturing.
