Classification and Mechanical Properties of Synthetic Polymers

Classification and Mechanical Properties of Synthetic Polymers

Synthetic polymers are classified as elastomers, fibers, or plastics based on their crystallinity. Crystallinity, the degree of long-range order in the solid state, influences the mechanical properties (stretching or contracting) of elastomers. Elastomers are flexible polymers that can expand or contract easily upon the application of an external force. They have numerous crosslinks that pull them back into their original shape when stress is removed. Silicones, for instance, are highly elastic...

Background:

Additive Manufacturing (AM) utilizes multirole materials, with Polyvinylidene fluoride (PVDF) being a prime candidate due to its unique properties.
Understanding the relationship between macroscopic mechanical behavior and microscopic structural mechanisms is crucial for optimizing AM components.

Purpose of the Study:

To establish a correlation between macroscopic mechanical behavior and microscopic structural mechanisms in AM PVDF.
To investigate the influence of deformation rate on the mechanical response of 3D printed PVDF components.
To evaluate the performance of AM PVDF under various strain rates relevant to real-life applications.

Main Methods:

Testing of AM PVDF samples across a range of strain rates (10-300 mm/min).
Characterization using thermogravimetric analysis, differential scanning calorimetry, rheological measurements, scanning electron microscopy, dynamic mechanical analysis, Raman spectroscopy, and energy-dispersive spectroscopy.
Evaluation of mechanical properties including ultimate and yield strengths, modulus of elasticity, toughness, flexural strength, Charpy impact strength, and Vickers hardness.

Main Results:

PVDF demonstrated a strain-hardening response, with strength increasing up to ~25% and stiffness by ~15% as loading speed increased.
AM PVDF samples exhibited resilience under extreme strain rate conditions.
Sensitivity index data provided insights into material response variations.

Conclusions:

The deformation rate can be effectively utilized to tailor the mechanical response of 3D printed PVDF components.
AM PVDF shows promising mechanical characteristics and resilience, making it suitable for demanding applications.
The study provides a comprehensive understanding of PVDF behavior under dynamic loading.
