Abaris Training offers classes and services to wind professionals of all types, from engineers to field support to technicians.
A five day composite windblade repair class is designed for both factory and field technicians, inspectors and supervisors responsible for performing structural repairs to composite wind blades. This class is devoted to hands-on repair practices with the appropriate balance of classroom time dedicated to learning about materials and processing relative to both the structure and the repair.
The windblade repair course promotes and utilizes multi-person team repair concepts similar to those done both in the factory and in the field. Students will be grouped in teams of two to work together on these projects.
In this course, the students will first be challenged with determining the extent of damage to Fiber Reinforced Plastic (FRP) sandwich panels and then will perform damage removal and proper repair preparation. Finally, the student teams will perform repairs to reconstruct the damaged areas in order to match the fiber axial loads through the damaged area in the structure.
This fundamental repair approach will be repeated again with another panel, so as to promote additional hands-on practice with the appropriate tools and equipment used in both factory and field repairs. During this repair, the student teams will be introduced to the latest hot-bond repair equipment specifically designed for the windblade repair industry.
This equipment will then be used to perform hot-bond repairs on the structure, with the students learning how to position, secure and control large area heat blankets in accordance with standard industry procedures.
For engineers, a five day structural engineering course for composite repair is specifically aimed at engineers who are responsible for the design development of both temporary and permanent repairs to primary and secondary composite structures.
This course will provide the participating engineers with skills in repair design development that will improve the structural integrity of repairs and significantly reduce repair re-work. The instruction follows the basic repair methodology covering the assessment of damage based on NDI results, the determination of structural integrity loss, which in turn leads to the type of repair design required, the analysis of a repair joint and the repair scheme instructions application.
During the course examples and exercises of damage analysis and repair design will utilize PC based software and will culminate in the actual repair of a damaged composite component. Numerical analysis and stress calculations are performed on PC based programs. Optimizations of repair design parameters to meet structural and geometric limitations are quickly identified and discussed.
