Low-velocity impact loading tests were performed on bending bars and the residual strength after the impact was evaluated by 4-point bending tests. The impact tests were monitored using an instrumented drop-weight machine. During impact, the composites absorbed higher energy than the monophase material. The strength retention, in percentage, after the impact was significantly higher for the composite that presented damage tolerance for impact energy levels higher than monophase alumina. These results are discussed and fractographic analysis was used to identify the mechanisms responsible for the lower strength degradation of the composite.engAl2O3Al2TiO5CompositesStrengthLow-velocity impactinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
