Manufacturing and researching composite materials comes with a host of interesting and challenging problems. Reinforcement and matrix materials often have significant differences in their material properties that affect the behavior of the composite material as a whole. Composites researchers and manufacturers may seek to understand:
- Mechanical properties of each constituent material
- Distribution of constituent materials
- Interfacial characteristics between matrix and reinforcement material
- Behavior at elevated or reduced temperature
- Dynamic mechanical properties
Bruker offers a suite of Hysitron nanomechanical test instruments to meet the mechanical testing needs for composites researchers and manufacturers. With our recently developed XPM (Accelerated Property Mapping) indentation technique, users can quickly obtain the mechanical properties of each material in their composites. Coupled with in-situ SPM Imaging, distribution of constituent materials can be easily measured. An electronic under-fill material was characterized using XPM. The results are shown in Figure 1.
