Process‐Informed Multiscale Prediction of Nonlinear Compressive Behavior in Direct Compounded Compression Molded Short Fiber Composite Lattice Structures

Runtian Zhao, Sizheng Gai, Haoyu Shi, Zhandong Wang et autres

ABSTRACT Direct compounded compression molding (DCCM) offers an efficient route for producing SFRTP lattice structures, but predicting their nonlinear compressive behavior is challenging due to spatially heterogeneous fiber orientations from the molding process. This study presents a process‐informed multiscale framework for such …

Temperature‐Dominated Deformation Mechanism and Quantitative Prediction of CF / PEKK Prepreg Tape in LAFP Process

Jianguo Liang, Senran Niu, Hui Li, Ting Wu et autres

ABSTRACT During laser‐assisted automated fiber placement (LAFP) in situ consolidation, width variations in prepreg tapes lead to gaps or overlaps between adjacent tapes, significantly impairing the forming quality of final components. This study investigates the deformation behavior of carbon fiber‐reinforced poly(ether‐ketone‐ketone) (CF/PEKK) …
