Composite materials are widely utilized by many different industries due to their high strength-to-weight and stiffness-to weight ratios. The properties of Glass Fiber Reinforced Polymer (GFRP) composites can exhibit significant differences during their in-service lifetime due to the surrounding environmental conditions such as temperature. This study investigated the possibility of their performance degradation with the Dynamic Mechanical Analysis (DMA) tests before long-term fatigue tests, which revealed that operation at high temperatures, below the glass transition temperature, may have significant effects on the strength and durability. The monotonic and fatigue tests results validated this assumption and highlighted the significance of these characterization methods beyond the information contained in the material datasheet.

This presentation will also explore the characterization of rubber materials with High-Force DMA testing. There are specific conditions such as sample size, stiffness, and/or force requirements that necessitate testing beyond the limit of conventional DMA methods. The case studies presented here will demonstrate why and when High-Force DMA testing will be highly valuable to characterize material response under in-service conditions.

What you will learn:
  • Why material datasheet may not be sufficient for material selection?
  • How DMA tests can inform monotonic and fatigue test conditions?
  • Why High-Force DMA test is necessary? How does it help to characterize material behavior during in-service conditions?
