| Research Abstract |
It is well known that braided fabric structures provide useful reinforcement configurations in the three dimensional composite materials. In this study our purpose was the establishment of automated manufacturing techniques of complex shaped braided preform for composite material. Concepts of CAE(computer aided engineering) system were proposed to develop new braiding machine based on new braiding mechanism. The simulation programs based on the CAE system were developed. Moreover, the new braiding machines were developed which can fabricate 3-D braided preforms with complex shaped cross section.
In the development of simulation programs, two concepts of CAE system were proposed to develop new braided fabrics which have complex shaped cross section and multi braid axs respectively. Simulation programs for fabrication of braids with complex shaped cross section can decide initial spindle setting pattern, predict braided structure and estimate regularity of braided structure. Simulation programs for fabrication of braids with multi braid axs can predict fiber orientation and thickness of braided structure.
Two new braiding machines were designed and developed. One can fabricate flat I-beam braid which constructed based on flat braided structure. Another can fabricate tubular I-beam braid which constructed based on tubular braided structure. A tubular I-beam braided composite indicated higher bending modulus and strength than I-beam mode of aluminum.
The tubular I-beam braided composite was expected to apply for various structural members.
