技术领域technical field
本发明涉及一种带锁扣的闭合件，尤其涉及一种带锁扣的纤维增强复合材料夹层板结构，可应用于汽车或飞机等工程机械的引擎盖、车门、尾箱盖等具有锁扣的闭合件。The invention relates to a closure with a lock, in particular to a fiber-reinforced composite sandwich panel structure with a lock, which can be applied to hoods, doors, trunk lids, etc. of construction machinery such as automobiles or airplanes. of the closure.
背景技术Background technique
近些年来，随着汽车保有量的逐步增加，进而造成的气候变化问题越来越严峻，从国家到汽车厂商都已认识到环境保护及合理利用能源的重要性。对于汽车产业来说，尤值当前各国大力发展新能源汽车之际，实现汽车的轻量化已经成为行业可持续发展的必经之路。而碳纤维复合材料由于其具备优异的综合性能，在汽车的轻量化之路上被寄予了极高期望。相对于当前汽车上应用的高强钢及铝合金等材料来说，在同等强度下，碳纤维复合材料的比重低于铝合金，更是远低于高强钢。除了质轻的优势外，碳纤维复合材料还具备高强度、高模量、耐腐蚀、耐高温等优良性能。由此可见，碳纤维复合材料在汽车工业中的应用具备非常大的潜力。In recent years, with the gradual increase in the number of automobiles, the problem of climate change has become more and more serious. From countries to automobile manufacturers, they have realized the importance of environmental protection and rational use of energy. For the automobile industry, especially at a time when countries are vigorously developing new energy vehicles, realizing the lightweight of automobiles has become the only way for the sustainable development of the industry. Due to its excellent comprehensive performance, carbon fiber composite materials have been placed on the road of lightweight automobiles with high expectations. Compared with the high-strength steels and aluminum alloys currently used in automobiles, under the same strength, the specific gravity of carbon fiber composites is lower than that of aluminum alloys, and is much lower than that of high-strength steels. In addition to the advantages of light weight, carbon fiber composite materials also have excellent properties such as high strength, high modulus, corrosion resistance, and high temperature resistance. It can be seen that the application of carbon fiber composite materials in the automotive industry has great potential.
虽说碳纤维复合材料在汽车上的应用前景广阔，但于当前其仍有一些问题尚待解决。如在传统的汽车覆盖件制造中，由于运用的材料主要为钢材，从而决定了覆盖件与其附件(例如锁扣)的连接方式之一便是焊接。而采用了纤维增强复合材料后，金属锁扣无法与碳纤维夹层板焊接连接，传统的连接方式已经无法适应新型应用的需求，从而有必要提出一种新的覆盖件与其附件的连接以及安装方式，以便于纤维增强复合材料在汽车工业中的进一步推广应用。Although carbon fiber composite materials have broad application prospects in automobiles, there are still some problems to be solved at present. For example, in the manufacture of traditional automobile cover parts, since the material used is mainly steel, one of the connection methods of the cover parts and its accessories (such as locks) is welding. After the use of fiber-reinforced composite materials, the metal lock can not be welded and connected to the carbon fiber sandwich panel, and the traditional connection method has been unable to meet the needs of new applications. Therefore, it is necessary to propose a new connection and installation method of the cover and its accessories. In order to facilitate the further promotion and application of fiber reinforced composite materials in the automobile industry.

具体实施方式Detailed ways
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
如图1-图3所示，一种带锁扣的纤维增强复合材料夹层板结构，包括由纤维增强复合材料制作的夹层板4、预设在夹层板4内的预埋件5、设置在夹层板4外且与预埋件5可拆卸连接的锁扣底座2以及安装在锁扣底座2上的锁扣1，其中，锁扣为金属锁扣。As shown in Fig. 1-Fig. 3, a fiber reinforced composite sandwich panel structure with locking buckle includes a
在本发明的优选实施例中，如图1、图2所示，预埋件5上设有多个螺孔5.3，锁扣底座2通过与螺孔相配置的螺栓3固定安装在预埋件5上。这样一方面方便了在夹层板成型后将其与锁扣底座安装在一起，另一方面通过螺纹连接使得锁扣与夹层板之间的连接更可靠，相对于只采用粘接来说这是更理想的连接方式。本实施例中螺孔的数量为2个，对称布置在锁扣的两侧。锁扣底座与预埋件通过螺栓连接，以方便在夹层板成型后锁扣的安装与更换。In a preferred embodiment of the present invention, as shown in Figures 1 and 2, the embedded
在本发明的优选实施例中，如图1-图3所示，夹层板4包括夹芯层4.2以及胶结在夹芯层上下两端的纤维层(上纤维层4.1和下纤维层4.3)，预埋件5设置在夹芯层内，锁扣底座2与其中一个纤维层(上纤维层4.1)接触。其中，纤维层由碳纤维增强材料和环氧树脂基体复合而成，具体为采用碳纤维作为增强材料，环氧树脂作为基体材料，通过两者的固化形成层合板结构，夹芯层所采用的材料主要为泡沫塑料。在纤维层与夹芯层之间设有一层胶结层，把夹芯层与上纤维层和下纤维层胶结在一起，从而使得夹层板的性能得到进一步提升。In a preferred embodiment of the present invention, as shown in Figures 1-3, the
在本发明的优选实施例中，如图2所示，为了满足夹层板不同区域对于力学性能的需求，在纤维层与预埋件接触面附近区域、纤维层与锁扣底座接触面附近区域的纤维层予以补强，即纤维层与预埋件和锁扣底座接触区域的厚度大于其它区域的厚度，通过这样的结构设计，可以使得夹层板的材料分布与其受力情况相适应，从而在没有过多增加材料及成本的情况下，获得更优的力学性能。纤维层不等厚的方式为：纤维层由多层纤维铺层构成，纤维层与预埋件和锁扣底座接触区域的纤维铺层的层数大于其它区域的纤维铺层的层数。In a preferred embodiment of the present invention, as shown in Figure 2, in order to meet the mechanical properties requirements of different areas of the sandwich panel, the area near the contact surface between the fiber layer and the embedded part and the area near the contact surface between the fiber layer and the lock base The fiber layer is reinforced, that is, the thickness of the contact area between the fiber layer and the embedded part and the lock base is greater than that of other areas. Through such a structural design, the material distribution of the sandwich panel can be adapted to its stress conditions, so that there is no When the material and cost are increased too much, better mechanical properties can be obtained. The unequal thickness of the fiber layer is as follows: the fiber layer is composed of multiple layers of fiber layers, and the number of layers of fiber layers in the contact area between the fiber layer and the embedded part and the lock base is greater than that in other areas.
在本发明的优选实施例中，如图2所示，预埋件上下两端面(预埋件上端5.1和预埋件下端5.2)分别与纤维层的内表面贴合，在预埋件的布置区域不引起夹层板表面的突变，这样一方面可保证夹层板表面的造型要求，另一方面也可避免在突变区域造成应力集中。预埋件与纤维层之间设置有胶结层，并根据受力情况，上下胶结层区域的面积设计为不等大，预埋件与上纤维层的接触面积小于与下纤维层的接触面积，预埋件在夹层板的厚度方向上为非对称结构，这样的材料布局既考虑了整个结构的受力情况，同时也兼顾了轻量化的设计要求。由于锁扣在其使用期主要受到拉力与压力作用，当其受拉时，易引起夹层板的上纤维层及下纤维层剥离，从而将预埋件的下端面设计得更大，以免在锁扣受拉时引起夹层板纤维层的剥离。In a preferred embodiment of the present invention, as shown in Figure 2, the upper and lower end surfaces of the embedded part (the upper end 5.1 of the embedded part and the lower end 5.2 of the embedded part) are respectively attached to the inner surface of the fiber layer. The area does not cause abrupt changes on the surface of the sandwich panel, so on the one hand, it can ensure the modeling requirements of the surface of the sandwich panel, and on the other hand, it can also avoid stress concentration in the abrupt change area. Between the embedded part and the fiber layer, there is a cemented layer, and according to the stress, the area of the upper and lower cemented layers is designed to be unequal, and the contact area between the embedded part and the upper fiber layer is smaller than the contact area with the lower fiber layer. The embedded parts have an asymmetric structure in the thickness direction of the sandwich panel. This material layout not only considers the stress of the entire structure, but also takes into account the lightweight design requirements. Since the lock is mainly subjected to tension and pressure during its use period, when it is pulled, it is easy to cause the upper and lower fiber layers of the sandwich panel to peel off, so the lower end face of the embedded part is designed to be larger. When the buckle is in tension, it causes the peeling of the fiber layer of the sandwich panel.
应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本发明所附权利要求的保护范围。It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes should fall within the protection scope of the appended claims of the present invention.
