Abstract: RTM technology can realize the near-net size forming of expansion section, and volume content of fiber can reach 53.1% to 59.9%. In this paper, the resin matrix, normal reinforced preform, inject equipment and mold involved in the preparation of normal reinforced preform/phenolic RTM expansion section were discussed. Phenolic resin as matrix, 2.5 D braided preform or needle punched preform as reinforcement to prepare composites through RTM process, and the related performance were analyzed. The results show that the interlaminar shear strength of expansion section is as high as 59.2 MPa, and the ablative erosion performance is improved significantly.

Key words: RTM, expansion section, preparation technology
