Fastening systems play a crucial role in the performance and integrity of sandwich panels made with composite materials. A proper fastening system for composite materials ensures that the sandwich panel is firmly attached to its support
The choice of the fastening system depends on the materials used for the sandwich panel, the application, and the required performance. Different various fastening systems, such as mechanical fasteners, adhesive bonding, and hybrid fastening systems, are used for sandwich panels.
Mechanical fasteners, such as rivets, screws, and bolts, are commonly used to join sandwich panels. The fastener’s size, shape, and spacing must be selected to avoid creating stress concentrations or deforming the panel.
Adhesive bonding is also commonly used for joining sandwich panels. The adhesive must be compatible with the materials used in the sandwich panel and be selected based on the application and required performance.
Hybrid fastening systems, which combine mechanical fastening and adhesive bonding, provide additional load transfer capacity and can improve the sandwich panel’s performance.
In summary, choosing the right fastening system is crucial for the performance and durability of sandwich panels, and it must be done with careful consideration of the materials used, application, and required performance.
