Abstract The phenolic aerogel composite is a new type of thermal protection material that can be widely used in aerospace and civil thermal protection. Because pure phenolic aerogel has poor strength and cannot be directly used for thermal protection, it must be reinforced by fibers and applied in the form of fiber reinforced phenolic aerogel composites. The performance of reinforcing fibers directly affects the thermal and physical properties of the phenolic aerogel composite. In this work, two different structural forms of fiber performs were used to prepare phenolic aerogel composites, and the density, thermal conductivity, compressive strength, tensile strength, strain coordination performance and anti-ablative performance of fiber reinforced phenolic aerogel composites were systematically studied. The results show that the phenolic aerogel composite prepared by 6 mm fiber preform with high ratio of continuous fiber and high density has high density and low thermal conductivity at room temperature, but its compressive strength, tensile strength, strain coordination performance and ablation performance are excellent than that prepared by 3 mm fiber. The research results provide technical support for the practical application of the subsequent phenolic aerogel composites. This work characterized and analyzed the properties of phenolic aerogel composites obtained from different fiber preforms, and clarified the effect of reinforcing fibers on the performance of phenolic aerogel composites.
