specific Embodiment approach 1

[0019] Specific Embodiment 1: In this embodiment, a kind of ablation material of phenolic resin impregnated carbon-based three-dimensional braided body is composed of 30-50 parts by weight of phenolic resin, 20-40 parts of fiber braided body, and 10-30 parts of phenolic modified Agent, 5-20 parts of filler, 10-20 parts of curing agent and 50-80 parts of organic solvent.

specific Embodiment approach 2

[0020] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the ablation material is modified by 35-50 parts of phenolic resin, 20-40 parts of fiber braid, and 20-30 parts of phenolic resin in parts by weight. Agent, 10-20 parts of filler, 10-20 parts of curing agent and 50-80 parts of organic solvent.

[0021] Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the phenolic resin is boron phenolic resin, which is used as the matrix of the ablation material to improve the heat resistance of the composite material.

[0023] Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses an ablative material of a phenolic resin impregnated carbon-based three-dimensional woven body and a preparation method of the ablative material, and relates to the technical field of ablative materials. The invention aims to solve the problems that a traditional ablation material cannot have excellent ablation resistance and mechanical properties at the same time, and the ablation material cannot resist multiple times of ablation. The method comprises the following steps: carrying out gradient heating curing on a phenolic sol solution, standing the cured phenolic sol in a sealing device, and drying to obtain phenolic aerogel; the preparation method comprises the following steps: adding a filling agent into phenolic aerogel, then adding a curing agent, and uniformly mixing to obtain slurry A; adding a filling agent into the phenolic aerogel, then adding a curing agent, and uniformly mixing to obtain slurry B; uniformly dipping the slurry A and the slurry B into a fiber woven body, then vacuumizing, curing, cooling to room temperature, and finally washing, aging and drying. The ablative material of the phenolic resin impregnated carbon-based three-dimensional woven body and the preparation method of the ablative material can be obtained.

Description

technical field [0001] The invention relates to the technical field of ablation materials, in particular to an ablation material impregnated with phenolic resin and a carbon-based three-dimensional braid and a preparation method thereof. Background technique [0002] Nowadays, reusable spacecraft is an important means to reduce the cost of space transportation, and it is also an effective way to improve the rapid response capability of space, and it can better play a potential strategic deterrent. Engines and electrical equipment.
