Abstract:

Aiming at the problem of bubbles or dry spots caused by incapability of completely removing local air or completely impregnating the effective area by resin in the resin injection for resin transfer molding (RTM), the mechanism of bubble wrapping and dry spot formation in RTM forming process was systematically analyzed. The influence of non-deterministic factors in RTM molding process on the flow quality of RTM resin injection was summarized and introduced, such as the regional distribution difference of preform permeability, the difference in interleaving law of preform yarn bundle, the difference in size of preform and cavity, the difference in number of inlet and outlet positions of RTM mould and the difference in requirements, and the new technologies and methods for regulating the flow shape of resin were put forward. Finally, the simulation of RTM resin flow process for T-type composite structural products was carried out, which provides a theoretical and method reference for the development of new RTM injection technology for composite materials with complicated structures.
