Abstract
Currently, in the shipbuilding industry, there are many parts and equipment that work at high temperatures such as Marine steam boilers, exhaust valves, solid fuel rocket engines,... therefore, manufacturing the thermal protection panels is necessary. Under the effect of high temperature, hardness, durability, the resistance to corrosion and abrasion decreases, and the microstructure of these materials can be changed in molecular structure. Carbon fabric-reinforced phenolic composite material is a heat-protective material based upon the ablation mechanism, which has confirmed advantages thanks to its high heat resistance and char content, as well as keeping the char layer configuration to heat and erosion resistance. To make products from this material, it is necessary to use hot compressing process. On the basis of analyzing thermodynamic properties of hexamine cured phenolic resin, a series of experiments were performed to stabilize the production process. The products is manufactured and tested for satisfactory performance. The post-experiment technology regime recommends the following: The pressing temperature fluctuates around 1600°C, the pressing pressure ranges from 20 to 30 MPa, the pressing time depends on the gelation process, so it takes 30 minutes for gelation and 30 to 45 minutes for solidification.
