Abstract: The carbon fiber reinforced epoxy resin 5284RTM/5228A composite laminates were fabricated via co-cured RTM process. The internal quality of laminates was analyzed using Ultrasonic C-Scan inspection and microscopic analysis, short beam shear strength and bending properties were measured to evaluate the inter-laminar property of laminates, and thermal properties were determined by DMA. The results show that the pretreatment of the prepreg layer has no significant effect on the internal quality, the mechanical property, and the heat resistance of laminates. Besides the application of thermosetting medi-layer did not affect the internal quality and the mechanical property, but caused the reduction of the heat resistance of laminates.
