A Materials Testing System / Un système d'essai de matériaux

我们需要一套拉力测试系统用于材料研究。该设备是测量聚合物基软材料机械性能的基本工具。我们一直在研究两种智能聚合物，它们可能会影响我们经济和社会的未来。第一种是形状记忆聚合物（SMPs），第二种是自愈合聚合物（SHPs）。smp可以在加热或暴露于光或超声波下改变其形状。这些材料有许多用途，如医疗植入装置。对于shp，它们可以自行修复损伤（裂纹或断裂）或借助光。由于具有此功能，它们延长了使用寿命，提高了安全性并降低了成本。我们的研究目标是开发新的SMP和SHP材料并发现新的应用。我们研究的实现需要使用拉伸测试设备，该设备基本上可以测量给定聚合物变形所需的力，提供有关断裂点的模量，电阻，应力和变形等力学性能的重要数据。

We request a tensile testing system for our materials research. This equipment is a basic tool for measuring the mechanical properties of our polymer-based soft materials. We have been working on two types of smart polymers that may impact the future of our economy and society. The first is named shape-memory polymers (SMPs) and the second is self- or stimuli-healable polymers (SHPs). SMPs can change their shape upon heating or exposure to light or ultrasound. These materials have many applications such as medical implant devices. As for SHPs, they can repair damage (crack or fracture) themself or with the help of light. By having this function, they have prolonged service lifetime, enhanced safety and reduced cost. Our research aims at developing new SMP and SHP materials and discovering new applications. The realization of our research requires the use of tensile testing equipment that basically measures the force needed for deforming a given polymer, providing important data about the mechanical properties such as modulus, resistance, stress and deformation at the breaking point.
