Evaluation of the effectiveness of channels in large filament bundles. (a) $-2R<x_1-x_2\le 0$ and $-4R<y_1-y_2<-2R$; (b) $0\le x_1-x_2<2R$ and $-4R<y_1-y_2<-2R$. (The red area represents the resin flow through the channel, while the blue area represents the position of the center of the circle of C2 and C3 that meets the specified requirements).
