Apparatus and method for reducing stress concentration at an edge of a laminated composite material

摘要

The invention relates to a device for reducing a stress concentration at an edge of a laminated composite material, wherein the device (1) comprises an optical element (2), an actuator element (3), and a receiving space (4) for a first component (5) has laminated composite material, wherein the first component (5) via a contact surface (6) with a second component (7) is connectable or connected and an edge element (8) over the contact surface (6), wherein the optical element (2) a Focusing surface (9) for a laser radiation for evaporating laminated composite material is defined, wherein the actuator element (3) for moving the optical element (2) around a in the receiving space (4) arranged first component (5) is formed, wherein the actuator element (3 ) aligns the optical element (2) on an edge element (8) such that an angle between the contact surface (6) and the focus surface (9) sweeping over the first component (8) is smaller than 90 ° st, wherein the angle is selected so that after evaporation of the laminated composite material on the focus surface (9), the stress concentration at the edge element (8) is reduced under load. The device avoids stress peaks at the edges of composite structures in overlapping areas.
