Composite materials can also be divided into two categories: commonly used and advanced.
Commonly used composite materials such as fiberglass are composed of lower performance reinforcements such as glass fibers and ordinary polymers (resins). Due to its low price, it has been extensively developed and widely used in ships, vehicles, chemical pipelines and storage tanks, building structures, sports goods, and other fields.
Advanced composite materials refer to composite materials composed of high-performance heat resistant polymers such as carbon fibers and aramid fibers, and later include metal based, ceramic based, carbon (graphite) based, and functional composite materials. Although their performance is excellent, their prices are relatively high, mainly used in national defense industry, aerospace, precision machinery, deep submersibles, robot structural components, and high-end sports equipment.
