he capacity to manufacture products with intricate geometries, coupled with the benefits of low mass, high stiffness, and strength, underpins the extensive utilization of polymer matrix composite (PMC) in the aviation sector, especially carbon-fiber-reinforced polymer (CFRP). This domain of application undeniably demands meticulous attention to the fabrication process of the structures. The method for crafting parts from CFRP relies on prepreg technology [1]. T
