| Abstract: | In order to reduce structural weight of composite RTM waved-beams with large size,the design work for complex thickness area of waved-beams is done through the software CATIA.The ply angle and stacking sequence of composite laminates is optimized and its static strength is calculated by coding FORTRAN program.The waved-beams shear test is performed.This waved-beam has been successfully applied to a certain aircraft and shows significant effect on reducing the structural weight. |
| Keywords: | RTM waved-beams optimization design CATIA FORTRAN test |
