在这项工作中，三个市售的陶瓷颗粒已被用作玻璃纤维增强环氧树脂复合材料的热障涂层。通过将70重量%的分散剂分散在丙烯酸树脂中来制备涂层。30重量%的陶瓷颗粒阻燃环氧树脂复合材料上的涂层的热障效率已被研究的温度梯度通过样品的厚度，而表面暴露于不同的热通量的辐射热。在锥形量热计中通过插入两个热电偶进行测试，在实验期间，一个在涂层下方，另一个在样品的反面。这也允许评估其可燃性性能。(C)2014爱思唯尔有限公司版权所有。
In this work, three commercially available ceramic particles have been used as thermal barrier coatings on glass fibre-reinforced epoxy composites. The coatings have been prepared by dispersing 70 wt.% ceramic particle in 30 wt.% flame retarded epoxy resin. The thermal barrier efficiency of the coatings on the composites has been studied in terms of temperature gradient through the thickness of the sample while the surface is exposed to a radiant heat of varying heat fluxes. The tests have been performed in a cone calorimeter by inserting two thermocouples, one underneath the coating and the other on the reverse side of the sample during the experiments. This also allowed evaluating their flammability performance. (C) 2014 Elsevier Ltd. All rights reserved.
