一、紧固件的类型与材料的选择目前碳纤维复合材料(以下简称复合材料)结构的连接仍以机械连接为主。参照国外复合材料结构所采用的紧固件,我们选择了高锁螺栓作为研究对象。这种新型紧固件具有强度高、重量轻、成本低、装配简单、效率高、噪音小等特点,同时可获得较高的可控制预紧力,有自锁能力,可在较小的空间进行单面安装,并能提高复合材料迭层板 First, the type of fastener and the choice of materials Currently carbon fiber composite materials (hereinafter referred to as the composite material) structure is still the main mechanical connection. With reference to the fasteners used in foreign composite structures, we chose the high-locking bolts as the research object. This new type of fastener features high strength, light weight, low cost, simple assembly, high efficiency and low noise, as well as high controllable pre-tightening force and self-locking capability in a small space Single-sided installation, and can improve composite laminate
