This document specifies a method using a thermal imaging camera for measuring the heat transfer parameter of PAN-based 12 K carbon fibre tow with a filament diameter of 7 µm. This document is applicable to both sized and unsized carbon fibres. NOTE At the time of publication, the experience is on 12 K tow. Other tows will be included when the experience becomes available.

Overview

ISO/TS 23483:2022 specifies a non-contact method for measuring the heat transfer parameter of polyacrylonitrile-based (PAN-based) carbon fibre tow using a thermal imaging camera. The technical specification is focused on 12 K carbon fibre tow (≈12 000 filaments) with a filament diameter of about 7 µm, and applies to both sized and unsized fibres. The method quantifies heat transfer using thermography and Fourier’s thermal conductivity relation to provide reproducible thermal-characterization data for carbon fibre tows.

Key Topics and Requirements

Scope: Measurement of PAN-based 12 K carbon fibre tow heat transfer parameter using a thermal imaging camera.

Measurement principle: Thermographic recording of temperature difference (ΔT = T1 − T2) between two electrode positions across a 15 mm active tow length; apply Fourier’s law K = L·Q / (ΔT·A).

Typical test parameters:

Active length between electrodes: 15 mm (mounted within a total tow length of 100 mm).
Cross-sectional area (document example): A = 4.89 × 10⁻⁷ m².
Thermal imaging camera resolution: minimum 640 × 480.
Emissivity: graphite/carbon emissivity at 298 K ≈ 0.97 (camera correction values for emissivity, distance, area required).
Camera-sample distance: 200–300 mm.
Power supply: DC, 50 V, 20 A, 1 000 W (constant).
Environmental conditions: 296 ±2 K and 50 ±10 % RH; use an adiabatic black box chamber to avoid convection.

Sampling & repeatability: Minimum five specimens, at least 15 measurement points per specimen; stop after 30 consecutive points and allow 30 s rest if needed.

Calibration & traceability: Annual calibration of thermal camera per manufacturer and national metrology institute procedures.

Reporting: Include test equipment, sample description, conditions, measured heat transfer parameter, date/time and other relevant influences.

Applications and Users

ISO/TS 23483:2022 is practical for:

Materials laboratories and accredited test houses performing thermal characterization of carbon fibres.

Composite manufacturers (aerospace, automotive, electronics, sporting goods) needing tow-level thermal data for thermal management, simulation, and process control.

R&D teams optimizing fibre sizing, tow architecture, or thermal conductivity models.

Quality control and incoming inspection processes where reproducible tow thermal properties are required.
