A tape spring is a thin-walled, straight strip of material with curved cross-section, and the current trend is towards tape springs made of carbon fibre reinforced plastic (CFRP). In this paper, performance of the CFRP tape spring was studied and its bending moment’s calculative formula during opposite-sense bending process was derivated, also, the theoretical formula’s accuracy was assessed by means of detailed, non-linear finite-element analysis. Subsequently, a CFRP tape spring was practical designed and manufactured through twiningmoulding workmanship, and some experiments were conducted to study its bending characters, verifying the validity of the theoretical analysis and finite element simulation perfectly.
