Investigating phase separation in elastomer-toughened adhesives with DMA

NETZSCH_DMA_elastomer toughened adhesive

Many of the polymers that are used in adhesives are relatively brittle materials. To improve their toughness, different fillers or toughening agents are incorporated in the adhesive formulations. Phase separation occurs during the process of monomer conversion to polymer. An understanding of the phase separation behavior under different curing conditions and the development of the morphology are important. This editorial summarizes the application of the DMA in the investigation of thermal properties and phase separation in elastomer-toughened ethyl cyanoacrylate adhesive bulk films.

Measuring Viscoelastic Properties of Fiber-Reinforced Epoxy

When it comes to the characterization of fiber reinforced composites with dynamic measuring techniques many options are available, but they all have pros and cons for different materials and applications. In their paper, Huayamares et al. set out to answer some relevant questions by comparing measurements in 3-point bending and torsion mode. We summarize the main findings of the scientific paper and explain the measurements as well as the corresponding interpretation of the results depending on the use case.
