| Abstract Scope |
Coal polymer composites are manufactured using waste coal produced during mining operations aiding to reduce the polluting effects of the waste coal in the environment as well as, reducing the amount of polymer needed in the composite. While a promising material, the micromechanical damage mechanisms under loading have not yet been investigated resulting in a gap of knowledge surrounding the dominating failure modes of this material. The effect of coal type (bituminous and sub-bituminous) and quantity on the mechanical properties and damage mechanisms is investigated using Nondestructive Evaluation (NDE) Methods. This work demonstrates the ability to implement in-situ NDE during loading allowing for observation of damage directly at the time and scale it occurs. Additionally, micro-indentation is used to validate damage mechanisms. NDE methods used in this work include in situ Acoustic Emissions (AE) and Digital Image Correlation (DIC) coupled with optical microscopy. |
