Glassfiber Mat Thermoplastic is becoming the material of choice for many automotive applications. Compared to metal, GMTs have higher strength-to-weight ratios and impact resistance. GMTs offer greater design flexibility and better resistance to chemicals and corrosion. They are also electrically insulating and have relatively high stiffness and good dimensional stability. GMTs have shorter molding cycle times so it’s cost effective when in mass production. Except for traditional GMTs, through the use of different fiber weave reinforcement, such as Stitched Glass and Aramid fabric, Polyester fiber twisted weave or Hybrid weave PP and Glass(Twintex®), the performance of GMTs will be advanced to reach requirements.
