| Résumé : |
This article investigated the fabrication and performance issues of large-scale composite T-joints. Carbon composite balsacored sandwich panels were fabricated as the horizontal and vertical elements of the T-joints. Four element concepts to join the sandwich panels were evaluated. All joint concepts in this study used a triangular balsa core insert with carbon face sheets made from 2-D and 3-D fabric reinforced materials to transfer load between the vertical and horizontal sandwich panels. The full-scale joint specimens were tested by supporting the ends of the horizontal panel and applying a pull-off load to the vertical member. The sequence of failure events was investigated. The paper outlines the various joining concepts utilizing 3-D preform material and ranks them based on mechanical performance. The study shows clearly the benefit of 3-D fabric as both the improved interlaminar properties and unique dimentional configuration can be used to optimize composite joint design. |
