Research on testing methods of tensile strength for tubular composite materials and grip prototype system

针对目前高强度管状复合材料测试方法和手段不成熟的问题,提出了管状复合材料拉伸强度的测试方法——整体拉伸法。通过对基础试验进行对比分析,研制出了一套整体拉伸专用夹具,并通过试验验证了夹具的可行性和优越性,从而突破了高强度管状复合材料强度测试时夹持困难的瓶颈。基于VB语言在Windows环境下,开发了适用于管状复合材料拉伸夹具设计的原型系统。该系统具有4个模块分别对应夹具的4个主要零件,能够根据用户需求生成相应的设计参数,适应各种尺寸复合材料圆管拉伸夹具的设计,具有简单、实用、高效等特点。

According to the immature testing methods of the current high-strength tubular composite materials,the article elucidates a method of tensile strength for tubular composite materials-the whole stretch method.Through comparative analysis on the basic experiments,the author developed a special grip for overall tensile testing,while also verifying the feasibility and superiority of the grip by experiments.Thereby breaking through the bottleneck of clamping difficulty with the high-strength tubular composite strength test.Based on VB language in Windows environment,developed a tensile grip prototype system suitable for tubular composite materials.The system has four modules corresponding the four main parts of the grip,according to user needs to generate the corresponding design parameters,it can be adapted to the design of various sizes of grip for tubular composite materials,which is simple,practical,and efficient.
