Description

T107 is a prepreg based on epoxy resin and reinforcing filler (unidirectional tapes or fabrics of various weaving) for producing details with operating temperatures up to 150 °C.

 Advantages:

  • High strength;
  • High impact- and cracking-resistance;
  • Glass-transition temperature is 175 °C.
