In aerospace applications, different sections of single, large composite parts can cure at different rates because of varying thicknesses and thermal conditions. Many aerospace projects use composite materials because they are very light and very strong. The most interesting manufacturing applications are often with the ultimate end users of thermosets and polymers. These properties ensure TPCs are in high demand as they allow designers to create lighter aircraft, faster cars, and stronger oil and gas pipes, windmills and turbines.įor the manufacturers of SMC/BMC and prepregs, cure monitoring is largely used to check consistency of the product, as assurance to their customers that these products will cure as expected. TPCs offer OEMs a unique opportunity to replace metals such as steel and aluminum with a lightweight and advanced material that offers excellent formability, corrosion resistance, and strength. In the development of raw resins, thermoplastic composites (TPCs) and thermosets, cure monitoring allows a researcher to see how the material cures, how fast it cures in response to different formulations, how the reaction responds to the additions of catalysts or additives, and how the reaction rate changes at different temperatures. Major application areas are aircrafts, automobile parts, missile technology, high speed machinery, equipment parts and building constructions. Manufacturing applications – aerospace, wind energy, automotive This is important in molding operations to determine when it is safe to demold the cured part and in composite manufacturing to determine when a laminated part is fully cured. Monitoring of the degree of cure of adhesives and resins is important for determining whether a particular batch of material has achieved the necessary mechanical properties, rather than just relying on manufacturers’ specifications and adjustment of process parameters.
