Root Explanation

Prepreg is formed from "pre-" (meaning before) and "preg" (derived from the word "impregnate", meaning to soak or saturate). The term refers to composite materials that are pre-impregnated with resin before being cured, indicating that the resin is applied before the final processing stage.

Memory Tip

Think of 'pre-' meaning before and 'preg' relating to soaking or saturating — this helps you remember that 'prepreg' refers to materials that are soaked with resin before they are processed.
