A recently filed patent (Publication Number: US20230251064A1) describes a new process for manufacturing ballistic panels. The panels are formed by arranging fiber bundles on a substrate to create layers that follow the shape of the panel. The fiber bundles are then secured to the substrate with stitches to form a preform layer. Additional layers of fiber bundles are arranged on top of the preform layer, with each layer following the shape of the panel and secured with stitches. A resin is then impregnated into the preform layers, and the resin is cured to form the ballistic panel. This process allows for the creation of near net-shape panels.

The patent also specifies that the resin used in the process is cured through a molding process, specifically compression molding. The fiber bundles used in the panels are made of aramid fibers, and the threads of the stitches also consist of aramid fibers. The thickness of the ballistic panel is less than 16 mm, and in some cases, it can be less than 8 mm.

The patent also mentions that the ballistic panels can be used in motor vehicles. This suggests that the panels are designed to provide protection against ballistic threats in automotive applications.

It is worth noting that the stitches used in the process are continuous, and the fiber bundles are in the form of plies. These details provide further insight into the manufacturing process and the structure of the ballistic panels.

Overall, this patent describes a novel process for manufacturing ballistic panels that offers advantages such as near net-shape formation, the use of aramid fibers, and the ability to create panels with a thickness of less than 16 mm. The panels can be used in motor vehicles to provide ballistic protection.
