["Introduction: The surface of aramid filament is smooth, which is a great defect for impact resistance and composite molding of aramid/epoxy composite. In this study, a new type of yarn-aramid core-spun yarn is introduced to the fabrication of compositematerials. It increases the friction among yarns and optimizes the performance of yarns.","Methods: To verify the improvement of yarn in the composite material, the hand lay-up process is used, and the first layer and the fourth layer are replaced by core-spun yarns in a four-layer composite configuration.","Results and Discussion: The energy absorption, and the damage of the impacted surface and the back surface are evaluated through the drop weight impact test. The yarn pull-out test can reflect the internal friction of fabric. The results show that the average energy absorption of new yarn in the first layer is 10 J cm(2)/g more than that in the fourth layer at a 90 degrees/45 degrees/-45 degrees/0 degrees configuration after the normalization, but the conclusion is contrary when the structure is -45 degrees/0 degrees/90 degrees/ 45 degrees. Under the structure of 90 degrees/45 degrees/-45 degrees/0 degrees, the damaged area of the fabric is larger when the aramid core-spun yarn is laid on the first layer, while a contrary result can be found for the structure of -45 degrees/0 degrees/90 degrees/45 degrees. The fundamental research will provide design ideas and supports for aramid composite."]
