Spread-tow carbon fiber yarns, fabrics and prepregs

Proprietary tow-opening technology producing thin, uniform spread carbon fiber yarns, woven fabrics, UD sheets and resin-impregnated prepregs for improved drape and impregnation.

Problem solved

Conventional carbon fiber tows are thick and difficult to drape or impregnate uniformly in complex or thin composite layups, limiting design freedom and increasing defects.

Application contexts

  • high-performance automotive panels
  • aerospace skins
  • sports equipment
  • metal-matrix composite development

Technical principle

Mechanical or pneumatic spreading of carbon fiber tows into flat tapes, followed by weaving or prepregging; enables higher fiber volume fraction and better resin flow in downstream molding.

Typical use cases

  • Thin, drapable prepreg for complex curved structures
  • High-Vf laminates for weight-critical parts
  • Precursor for carbon/aluminum matrix composites
