Adhesive materials for carbon fiber reinforced polymer (CFRP) composites have attracted the interest of researchers as an effective means to bond newly developed lightweight and high-performance composite structures. In this study, we developed a novel method to overcome these critical problems through a silica particle coating. Four-step bonding procedures were proposed to bind heterogeneous materials, where various concentrations of silica particles were introduced to coat CFRP composite surfaces uniformly in order to serve as a reinforcement and as a protection barrier layer against CFRP fractures. Experimental evaluations of the mechanics and fractography studies were conducted to clarify the correlations among the silica concentrations, adhesive strength levels, coating properties, and CFRP surface fractures. It was demonstrated that the introduction of the silica surface coating improves the adhesive strength by approximately 20% while also reducing CFRP surface fractures significantly by around 90%.

碳纤维增强聚合物（CFRP）复合材料的粘合材料吸引了研究人员的兴趣，将其作为粘合新开发的轻质和高性能复合材料结构的有效手段。在这项研究中，我们开发了一种通过二氧化硅颗粒涂层克服这些关键问题的新​​颖方法。提出了四步粘结程序来粘结异质材料，其中引入各种浓度的二氧化硅颗粒以均匀地涂覆CFRP复合材料表面，以用作增强材料和保护层，以抵抗CFRP断裂。进行了力学和分形学研究的实验评估，以阐明二氧化硅浓度，粘合强度水平，涂层性能和CFRP表面断裂之间的相关性。
