2.ABS composite, ABS may not break, but its compressive strength and rigidity are too poor, it is easy to be crushed and deformed, and its protective ability is limited.
3. Glass fiber reinforced plastic (GRP), that is, glass fiber reinforced material, is a composite material of glass fiber and one or more thermosetting or thermoplastic resins; Its compression resistance, impact resistance and rigidity are much higher than ABS, but its weight is heavier.
4. Carbon fiber is a new material with many valuable electrical, thermal and mechanical properties. Stronger than steel, less dense than aluminum, more corrosion-resistant than stainless steel, more heat-resistant than heat-resistant steel, and can conduct electricity like copper.
