TOW-SPREADING TECHNOLOGY AND EQUIPMENT

Abstract

Abstract: Compared to conventional carbon fabric, fiber tow in the spread tow fabric (STF) is spread before weacing. Advantages of STF such as relatively straighter fibers, less crimp and better surface smoothness were established. Thereby it results in the final composite material product with better mechanical performance. This paper introduces spread tow technology, presents mechanical multi-rollers, acoustic energy, ultrasonic and air flow tow spreading methods and related equipment in detail.

Key words: tow spreading, mechanical multi-rollers, air flow, ultrasonic, acoustic energy
