碳纤维方管-纤维方管骨架开口检具

目前，汽车检具中应用碳纤维方管复合材料的案例比较多，特别是对前风窗框，车门框，行李箱框等便携手持式检具而言，检具的自重越轻越好，例如，前挡风开口检具，过去以铝管骨架加上树脂模拟块，这样一个检具重量约为30KG，但是由于铝管的强度有限，一旦使用评率过高，铝管骨架会产生不同程度的变形，从而导致检具精度存在偏差，使用碳纤维复合材料制作这种检具，总重量仅为10-15KG,而且使用寿命长，能有效保证检具的测试精度，一些大型汽车厂商对于利用碳纤维材料减轻自重这一方面也相当重视，例如上海通用一直积极地对检具本身的材料进行优化升级，从初的618车型的前后灯树脂开口检具，发展到E12全碳素的前后风挡开口检具，目前正从碳纤维骨架加树脂模拟块向全碳纤维一体式检具发展。

碳纤维复合材料在不同类型的汽车夹具中的应用程度不同，实现的轻量化效果也不同，但实际应用效果还是很令人满意的，例如，一种碳纤维汽车车灯的检具，该检具使用与汽车车灯外形一致的碳纤维本体，该碳纤维本体靠近汽车车灯的一侧面上设有定位模块，刚性定位模块处设有螺纹套，其中，作为检具本体的碳纤维材料只需要5mm厚度就可以满足强度要求，质量轻，变形量小，同时可以模拟整个车灯型面，外观也比较好。（碳纤维方管）

At present, there are many cases of applying carbon fiber composite materials in automobile inspection tools, especially for portable hand-held inspection tools such as front windshield frames, door frames, and trunk frames. The lighter the weight of the inspection tools, the better, for example, the front Windshield opening inspection tool, aluminum tube frame plus resin simulation block in the past, the weight of such a inspection tool is about 30KG, but due to the limited strength of aluminum tube, once the evaluation rate is too high, the aluminum tube frame will be deformed to varying degrees , Resulting in deviations in the accuracy of the inspection tool. The total weight of this inspection tool is only 10-15KG, and the service life is long. It can effectively ensure the accuracy of the inspection tool. Some large automobile manufacturers are less inclined to use carbon fiber materials. Self-weight is also very important. For example, Shanghai GM has been actively optimizing and upgrading the materials of the inspection tools. From the original 618 model front and rear light resin opening inspection tools to the E12 all-carbon front and rear windshield opening inspection tools, At present, it is developing from a carbon fiber skeleton with a resin simulation block to a full carbon fiber integrated inspection tool.
