1. Plural of prepeg; composite materials consisting of reinforcing fibers (such as carbon or glass) pre-impregnated with resin, used in manufacturing lightweight structural components.
Usage: technical; materials science; commonly used in aerospace and automotive industries

Examples

• The aircraft manufacturer uses prepregs to build wings that are both strong and lightweight.
• Carbon fiber prepregs are stored in freezers to prevent the resin from curing prematurely.
• Engineers selected prepregs for this project because they offer excellent strength-to-weight ratios.
• The company invested in new equipment to process prepregs more efficiently.
• Prepregs eliminate the need for separate resin mixing on the production floor.
