The main objective of this paper is to analyze the injection cycle in manufacturing of rectangular, rhombus, triangular, trapezoidal parts by using of the resin transfer method. To this end, the resin flow of the injection cycle in rectangular, rhombus, triangular, trapezoidal molds is studied using both experimental method and numerical simulation. Injection cycle is modeled for two composite parts with glass resin epoxy fibers. The injection device is used for experimental measurements. The available resin in the injection mold and its movement toward forward and permeability in rectangular, rhombus, triangular, trapezoidal molds are measured by using this system. Different tests were conducted for woven glass fibers. Then, the finite volume method was used to model the flow of resin in four molds. Finally, the injection time for glass fiber was determined by experimental and numerical methods, and numerical simulation results were compared with experimental measurements. In this research, resin velocity graphs for woven glass fibers are plotted, which show a decrease in the velocity of the resin from the injection site. It was observed in a 90 layout with a woven vertical glass fiber with a porosity of 0.6607, the rate of resin advance compared to porosity is 0.623, and also porosity permeability graphs are presented in a layout for glass fibers. The porosity in the glass fibers in the 9-layer mode was 0.6607, and in the 10-layer mode, it was equal to 0.623.
