A shot from our Advanced Composites & Technologies Class. Polyester resins are the workhorse of the composites industry and represent approximately 75% of the total resins used. They have been found to have almost unlimited usefulness in all segments of the composites industry. The principle advantage of these resins is a balance of properties (including mechanical, chemical, and electrical) dimensional stability, cost and ease of handling or processing. ⠀ #CarbonFiber #SandwichPanel #Aerospace #AerospaceEngineering #SpaceX #SkilledTrade #WorkWithYourHands
