The utilization of adhesive compounds in bonding lightweight and high-performance composite structures, including carbon fiber reinforced polymer (CFRP) composites, has garnered significant attention from researchers. This study presents the novel application of AlO coated with TiO as a thermal protective layer for CFRP substrate. Initially, the CFRP substrate underwent a protective treatment involving the application of AlO as a middle coat, followed by a further protective layer consisting of TiO as a top coat. The deposition of TiO onto an AlO-based thermal barrier coating (TBC) was carried out utilizing the flame spray method. The use of a TiO coating as a top coat was employed to enhance protection and heat dispersion across the middle coat and substrate. In order to achieve sufficient adhesion between the CFRP substrate, an intermediate coat consisting of AlO with a NaSiO binder, the impact of varying nozzle distances on adhesion strength and pull-off test outcomes was investigated, with a nozzle distance of 180 mm yielding the highest adhesion strength. The thermal stability of a CFRP substrate was enhanced through the deposition of a layer of TiO on AlO. The surface and cross-sectional morphologies of the composite were analyzed using a Scanning Electron Microscope (SEM). It was observed that the presence of a TBC on the composite surface effectively reduced the amount of heat that was transferred to the composite material. In order to assess the effectiveness of TBC on CFRP substrates, a series of experiments involving thermal torch and conductivity tests were undertaken. The interaction between the top and middle coats of a composite material results in enhanced mechanical properties, hence improving its thermal insulation capabilities. The artificially produced TBC coatings have the potential to function as adhesive materials, ensuring the sustained high performance of CFRP substrates.
粘合剂化合物在粘结包括碳纤维增强聚合物（CFRP）复合材料在内的轻质高性能复合结构中的应用，已引起研究人员的广泛关注。本研究提出了以TiO包覆的AlO作为CFRP基材热保护层的新应用。最初，CFRP基材进行了一种保护处理，即先涂覆AlO作为中间涂层，然后再涂覆一层由TiO组成的顶层涂层作为进一步的保护层。利用火焰喷涂法将TiO沉积到基于AlO的热障涂层（TBC）上。使用TiO涂层作为顶层涂层是为了增强对中间涂层和基材的保护以及热分散。为了使CFRP基材之间具有足够的附着力，使用了由带有NaSiO粘合剂的AlO组成的中间涂层，研究了不同喷嘴距离对附着力强度和拉拔试验结果的影响，喷嘴距离为180 mm时附着力强度最高。通过在AlO上沉积一层TiO提高了CFRP基材的热稳定性。使用扫描电子显微镜（SEM）分析了复合材料的表面和横截面形态。观察到复合材料表面存在TBC有效地减少了传递到复合材料的热量。为了评估TBC对CFRP基材的有效性，进行了一系列包括热喷枪和电导率测试的实验。复合材料顶层和中间层之间的相互作用导致机械性能增强，从而提高了其隔热能力。人工制备的TBC涂层有潜力用作粘合剂材料，确保CFRP基材持续的高性能表现。
