Ply Cutting Services
Ply cutting is the process of precisely cutting sheets of composite reinforcement material, like carbon fiber, fiberglass, or pre-preg, into the exact shapes needed for a laminate layup, before the part is molded and cured. Accurate ply cutting is foundational to a strong, consistent final part: even the best layup technician can’t compensate for a poorly cut ply. It also saves time and reduces waste for projects.
Custom Composite Technologies uses CNC and waterjet cutting to produce precision ply kits for our own production and for customers who need cut materials ready for their own layup process. Accurate, repeatable cutting means less material waste, faster layup time, and parts that meet spec the first time.
Why Precision Ply Cutting Matters
- Consistency across every ply — critical for parts where fiber orientation and coverage directly affect structural performance
- Material efficiency — precision nesting minimizes scrap on expensive carbon fiber and pre-preg materials
- Faster, more accurate layup — pre-cut, kitted plies reduce layup time and human error on the shop floor
- Repeatability for production runs — essential for limited production and semi-production programs where every part needs to match the last
How It Works
- Digital Nesting — Ply patterns are nested for maximum material efficiency
- CNC or Waterjet Cutting — Material is cut to precise tolerances using the method best suited to the material type
- Kitting — Cut plies are organized and labeled by layup sequence for fast, accurate assembly
- Delivery or In-House Layup — Kits are shipped to your facility or moved directly into CCTI’s own layup process
FAQ
What is ply cutting in composite manufacturing?
Ply cutting is the process of cutting composite reinforcement materials — such as carbon fiber, fiberglass, or pre-preg — into precise shapes for laminate layup, typically using CNC or waterjet cutting equipment for accuracy and repeatability.
Why use CNC or waterjet cutting instead of hand-cutting composite plies?
CNC and waterjet cutting deliver tighter tolerances, more consistent fiber orientation, and better material utilization (less scrap) than hand-cutting, which is especially important for structural parts and for programs running multiple identical builds.
Can CCTI supply cut ply kits without doing the full layup and molding?
Yes. CCTI can provide precision-cut, kitted ply materials for customers handling their own layup process, or manage the full process from cutting through cured part.
What materials can be ply cut?
CCTI’s ply cutting services handle carbon fiber, fiberglass, and pre-preg reinforcement materials used in composite layups.
