Abstract

This paper examines the main technologies and mechanisms used in the curing process of multilayer thick-walled parts of unmanned aerial vehicles (UAVs) made of polymer composite materials (PCM) based on epoxy resin. The study provides a detailed analysis of the technological features of the curing process, its kinetics, and the influence of heat transfer mechanisms on the final quality of molded components. It is emphasized that due to the low thermal conductivity of PCM, temperature inhomogeneity may occur during curing, leading to defects, internal stresses, and deterioration of the mechanical properties of the product. Therefore, ensuring uniform temperature distribution throughout the process is a key factor. Various curing methods are also considered, including convection heating, infrared (IR) heating, and pressing. These methods are compared in terms of heat distribution uniformity, energy consumption, curing time, and their impact on the mechanical properties of composite materials. The study identifies the key advantages of IR heating, such as process acceleration, improved mechanical strength of the product, and reduced thermal gradients. In addition, practical recommendations are proposed for precise control of temperature regimes, ensuring uniform heat distribution, and optimizing curing conditions. Implementing these recommendations will allow for the production of PCM-based components with enhanced performance characteristics.
