GMT is actually a prepreg of glass fiber thermoplastic, similar to thermosetting SMC, which is a semi-finished sheet made of glass fiber and thermoplastic. It can be softened by heating and then placed in a press to make various products by pressing and cooling.
Compared with other materials, GMT materials also have more advantages:
Advantages of GMT vs SMC
1. Easy to recycle, regenerate and reuse
2. Good toughness and impact resistance
3. The prepreg (raw materials in the form of products) can be stored for a long time
4. Low density
5. No toxic and harmful volatiles are produced during molding
6. Good fatigue and a strong ability to resist crack development
7. Large damping. Good noise and shock absorption performance
8. Excellent resistance to humidity and heat aging
9. Easy molding and short cycle
Advantages of GMT compared with steel
1. Low density, lightweight and high strength
2. Low mold cost
3. Corrosion resistance
4. Impact resistance
5. More design freedom, easy to realize one-time molding of complex parts
With the deepening of new process development and application technology research, they will definitely be more and more widely used in the field of compression molding processing.
