Performance regulation and intelligent application of 4D-printed carbon fiber-reinforced TPU/PLA/CF composites
This study aims to develop carbon fiber (CF)-reinforced thermoplastic polyurethane/polylactic acid (TPU/PLA) composite filaments tailored for 4D printing, with systematic investigation into the effects of CF content on material properties and shape memory behavior. Dog-bone tensile coupons, rectangular strips, complex...
