Research advances in biomimetic design and multi-point forming flexible manufacturing for curved surface of fiber composites
Fiber composites are widely uesd in aerospace,rail transportation and other fields due to their high specific strength,high spe-cific modulus,strong designability and other characteristics.With the increasing demand for the performance of fiber composite compo-nents,achieving the enhancement of the performance of fiber composites through the regulating of the material composition has reached the bottleneck,and the manufacturing technology of traditional fiber composite components is also difficult to meet the"multi-species,small batch"of fiber composite curved components precision forming manufacturing needs.In response to these problems,based on the concept of biomimetic design,the"Multi-point Forming Flexible Smart Manufacturing"team of Jilin University applied the biological structural characteristics of nature to the optimal design of fiber composite components,and developed a novel dactyl-inspired helical-fiber sinusoid-al-structure laminate(HSL),a novel dactyl-inspired basalt fiber-reinforced sandwich-structural composite(BFSC),a biomimetic lami-nated basalt fiber-reinforced composite(BL-BFRC),a double-twisted basalt fiber-reinforced composite(DT-BFRC),a bioinspired Janus fiber metal laminate(BJFML)and a dactyl-inspired sinusoidal-corrugated helicoidal sandwich-structural honeycomb(DSHSH),which realized the improvement of material performance.The carbon fiber composite wing skin was successfully manufactured by multi-point flexi-ble forming technology,and new equipment and technology of multi-point flexible and accurate forming of composite curved components were developed.
