Dust Extraction for Carbon Fibre & Composite Manufacturing

Carbon fibre reinforced polymer (CFRP) and glass fibre reinforced polymer (GFRP) machining, cutting, sanding, drilling and trimming generates respirable dust that is classified as a hazardous substance under COSHH. Carbon fibre dust particles are conductive, sub-micron in diameter and penetrate standard filtration. H-Class extraction is the correct specification for CFRP operations. M-Class is the minimum for GFRP.

Why carbon fibre dust requires H-Class extraction

Carbon fibre filaments fracture during machining into respirable fragments typically 5–7 microns in diameter and sub-micron fragments from dry sanding operations. The HSE classifies carbon fibre dust as a hazardous substance under COSHH with a workplace exposure limit (WEL) under EH40. Key hazards:

Respiratory — sub-micron CFRP particles penetrate deep into lung tissue. Long-term exposure causes pulmonary fibrosis in animal studies; precautionary COSHH approach mandates H-Class containment.
Electrical conductivity — carbon fibre is electrically conductive. Dust deposited on PCBs, switchgear and electrical equipment causes short circuits and equipment failure. Standard vacuum exhausts recirculate conductive dust into the environment.
DSEAR risk — carbon fibre dust in suspension is potentially combustible in certain concentration ranges. DSEAR risk assessment required for machining operations.

H-Class extraction with sealed H14 HEPA filtration captures carbon fibre dust at source and contains it within the filter system. No recirculation of conductive or respirable particles.

Where this applies — composite manufacturing sectors

Aerospace — CFRP fuselage panels, wing components, nacelles, interior trim. Strict OEM and NADCAP quality requirements for cleanliness during machining.
Motorsport — Formula 1, GT, endurance racing. Carbon fibre bodywork, monocoques, aerodynamic components. High machining volume, sub-micron dust generation.
Marine — GRP boat hull lamination, CFRP mast and spar machining, composite superstructure fabrication.
Wind energy — GFRP and CFRP blade manufacture and repair. Blade tip lengths require large-format panel machining with high extraction volumes.
Automotive — structural CFRP components, body panels, EV battery enclosures, interior trim.
Sports and leisure — bicycle frames, sporting goods, prosthetics and orthotics.

Legislation that applies

COSHH Regulations 2002 — carbon fibre dust is a hazardous substance. COSHH assessment required for all CFRP machining operations. H-Class extraction is the control measure for respirable CFRP dust.

HSE EH40 — man-made mineral fibre WEL 1 mg/m³ respirable. Carbon fibre treated as precautionary H-Class given sub-micron particle generation and conductivity risk.

DSEAR and ATEX — carbon fibre dust risk assessment required where machining operations generate suspended dust above minimum explosive concentration.

PUWER 1998 — LEV equipment (dust extraction) must be suitable for the intended use and maintained in efficient working order.
