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

我们需要一套拉伸测试系统用于我们的材料研究。该设备是测量以聚合物为基础的软材料的机械性能的基本工具。我们一直在研究两种类型的智能聚合物，它们可能会影响我们的经济和社会的未来。第一种是形状记忆聚合物(SMPS)，第二种是自愈合或刺激修复聚合物(SHPS)。SMP在加热或暴露在光或超声波下时会改变其形状。这些材料有许多应用，如医疗植入设备。至于SHPS，它们可以自己修复损伤(裂缝或骨折)，也可以在光的帮助下修复。具有此功能，延长了使用寿命，增强了安全性，降低了成本。我们的研究旨在开发新的SMP和SHP材料，并发现新的应用。要实现我们的研究，需要使用拉伸测试设备，该设备基本上测量变形给定聚合物所需的力，提供有关断裂点处的弹性系数、阻力、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.
