When it comes to selecting materials for your next innovative product, the material specification sheet is likely the first place that you will turn. This document provides core properties measured by the manufacturer and serves as an essential tool for supplier verification and new product development. However, while these sheets are reliable and provide a standard method for comparison, they often fail to tell the whole story.
Our world is brimming with viscoelastic materials: The dough you knead before baking a fresh loaf, the Silly Putty your toddler slaps against the wall, the rubber gaskets that create an airtight seal on an airplane door. Testing those materials by applying controlled deformations (strains) or forces (stresses) at various timescales, temperatures, and/or humidities allows for the optimization of properties and ensures durability and safety.
The composites market is evolving fast. Global market projections indicate a 10.8 % growth by 2028, driven by the demand for composites across industries looking for materials with superior performance at reduced weight and cost.1 This blog explores how advanced material analysis can enhance R&D and manufacturing processes in the composites market, ultimately leading to financial savings and increased efficiency.
从医疗设备的塑料到轮胎的橡胶,我们使用的材料必须满足越来越高的要求。产品制造商和消费者希望他们的材料外观漂亮,性能好,成本低,同时对环境友好。如需满足上述需求,就必须深入了解从分子水平到实际机械性能的材料特性。由于影响材料特性的因素有很多,因此需要精确的测量工具和方法来确保材料满足应用的高期望值。在开发和生产的各个阶段,评估材料特性的一个关键测量和分析方法是动态机械分析(DMA)。
High-performance polymers are a critical material for manufacturers due to their combination of mechanical, thermal, and chemical properties, but especially their cost. Without adequate testing, manufacturers could run into a slew of issues, from immediate product failure to poor performance or failure after some time in usage.
From material selection and failure analysis to end-use application, Dynamic Mechanical Analysis (DMA) offers crucial polymer insights. Polymer scientists and design engineers pair DMA with fatigue testing to gain a complete view of their material’s properties and performance attributes.
