摘要： A method of making a structural part having a thermal protection barrier, the method comprising at least the following steps: making a fiber structure; introducing the fiber structure into an injection mold having first and second chambers, the fiber structure being placed in the second chamber; placing a movable separator partition between the first and second chambers; injecting a first resin into the first chamber; solidifying the resin injected into the first chamber; withdrawing the movable separator partition; injecting a second resin into the second chamber containing the fiber texture; and hardening the resins present in the first and second chambers of the injection mold in such a manner as to obtain a part having a structural core made of composite material constituted by fiber reinforcement densified by an organic matrix, and a thermal barrier constituted by a layer of hardened resin.
