Plane‐woven‐fabric carbon‐fiber‐reinforced SiC/C matrix composites were fabricated at 1450°C via reaction bonding and impregnation with phenolic resin. The relationship between the flexural strength and the open porosity of the composites is dependent on the heat‐treatment temperature before the impregnation. The flexural strength of composites heat‐treated at 1000°C (open porosity of ∼15%) was ∼300 MPa, whereas that of composites heat‐treated at 1450°C (open porosity of ∼12%) was only ∼240 MPa. The heat‐treatment temperatures before the impregnation step might control the interface properties between the fiber and the matrix.
