Ablation behavior and mechanism of Ti3SiC2 modified carbon fiber/boron phenolic resin ceramizable composite
Carbon fiber/phenolic resin composite is prone to oxidation failure. In this work, Ti3SiC2 modified carbon fiber/boron phenolic resin ceramizable composite with excellent oxidation corrosion and ablation resistance was fabricated. It exhibited near-zero ablation characteristics with the linear ablation rate at 3000 °C for 20 s being -0.00859 mm/s. The ablation mechanism was investigated based on the ablation behavior, microstructure evolution, phase evolution and thermodynamic analysis. A thermal protection barrier composed of carbon-containing multiphase ceramics was in-situ constructed during ablation by sacrificing Ti3SiC2 and exerting the functions of oxygen consumption, oxygen inhibition, self-healing, carbon fixation and reaction heat absorption.
期刊介绍：
Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology.
Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal.
However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
