Composite Material Cutting Machines for Carbon Fiber, Fiberglass & Insulation Panels

Cutting composite materials such as carbon fiber, fiberglass, aramid, phenolic board and insulation panels is demanding work – fibers fray easily, dust must be controlled and patterns have to stay accurate under high production pressure.​
Shilai composite material cutting machines combine CNC oscillating knife technology, intelligent nesting and powerful drive systems to cut dry fabrics, prepregs and rigid panels with clean edges, stable quality and high yield.​
Whether you serve aerospace, automotive, marine, wind energy or HVAC ducting, our composite cutting solutions help you reduce manual work, improve material utilization and bring digital precision to your production.​
Share your material type, layer structure and production targets with our team, and get a tailored CNC composite cutting solution directly from the manufacturer.

Shilai offers dedicated composite cutting models for dry fabrics, sticky prepregs, rigid insulation boards and phenolic duct panels, so you can match the machine to your main material and process.​
From large-format fiberglass cutting tables to specialized prepreg and aramid machines, each model is engineered to handle the challenges of its target material while maximizing yield and throughput.

A composite material cutting machine is a CNC-controlled oscillating knife cutting system designed to process technical materials such as carbon fiber, fiberglass, aramid, phenolic boards and insulation panels according to digital patterns.​
Unlike manual cutting or simple saws, it uses specialized blades, drive systems and nesting software to handle tough fibers, sticky prepregs and dusty insulation materials with repeatable accuracy and controlled edge quality.​
By replacing manual marking and cutting with digital workflows, composite cutting machines help manufacturers improve productivity, reduce waste and ensure consistent part quality in safety-critical industries.​

Typical materials you can cut

• Dry fabrics: carbon fiber, fiberglass, basalt, aramid and hybrid fiber fabrics.​
• Prepregs: carbon fiber, glass fiber and other resin-impregnated materials with tacky surfaces.​
• Insulation and duct panels: phenolic duct board, PIR/PUR foam, fiberglass wool, mineral wool and rock wool.​
• Technical textiles and foams: technical fabrics, rubber foam, acoustic and thermal insulation layers.​

• Clean, fray-free edges: specialized straight and serrated blades handle carbon fiber, fiberglass and aramid cleanly, minimizing fraying and delamination.​
• High material yield: intelligent nesting arranges patterns to reduce offcuts and maximize material usage on expensive technical fabrics and prepregs.​
• Stable quality for critical parts: CNC control keeps dimensions and hole positions consistent across batches, which is essential for aerospace, automotive and protective equipment.
• Less manual labor and rework: automated feeding, marking and cutting reduce dependence on skilled manual operators and cut rework caused by inaccurate hand cutting.​
• Better dust and fiber control: dedicated cutting strategies and optional dust extraction help reduce airborne fibers and improve workshop safety.​
• Flexible production: easily switch between material types, thicknesses and layups without new tools, supporting both prototype and mass production

• High-frequency oscillating knife heads with interchangeable blades for dry fabrics, sticky prepregs and rigid boards.​
• Intelligent nesting software to optimize layouts by fiber orientation, cutting direction and material roll width.​
• Conveyor and flatbed options to feed rolls, sheets and board materials efficiently.​
• Marking options for alignment, ply IDs and assembly marks to support downstream layup and assembly processes.​
• Robust machine frames and drive systems designed for high-traction cutting of tough composite fibers

Shilai composite cutting machines support manufacturers across multiple high-performance industries where part accuracy, fiber integrity and process stability are critical.​

Aerospace & motorsport
Carbon fiber prepregs and dry fabrics for aircraft components, racing car parts and structural panels are cut with tight tolerances and controlled fiber orientation.​
Digital nesting and accurate cutting help reduce scrap on costly aerospace-grade materials and support repeatable laminate schedules.​

Automotive & transportation
Composite cutting machines process carbon and glass fiber parts for body components, interior structures and lightweight reinforcements in cars, trucks and rail vehicles.​
Consistent cuts and reliable nesting improve fit, bonding quality and weight control across high-volume production runs.​

Marine & wind energy
Fiberglass and composite fabrics for boat hulls, decks, wind turbine blades and structural cores are cut efficiently from wide rolls.​
Conveyor systems and nesting software help handle large-format patterns and long panels with minimal material waste.​

HVAC ducting & insulation
Phenolic duct boards, fiberglass wool and other insulation materials are cut for HVAC duct systems, building insulation and acoustic panels.​
Automated V-cutting and panel cutting enable precise duct folding, airtight joints and cleaner, safer handling of dusty materials.​

Protective equipment & technical textiles
Aramid and Kevlar fabrics for ballistic vests, helmets and protective apparel require clean, fray-free cuts with stable geometry.​
Specialized blade configurations and cutting strategies help maintain fiber integrity and edge quality for multilayer protective systems.
