please explain is details this thought Experiment: A composite material is composed of two mixed materials. Composites can take many forms, like mixed metals, mixed polymers, mixed liquids, mixed gases, liquids dispersed in polymers, solids suspended in liquids, etc. Essentially, any singular system in which two or more distinct phases can be identified can loosely be called a composite (for example, we might define an immiscible mixture of water and oil as a composite, but we would not define saline...
