Continuous multi-filament TOW.

The most common form of carbon fibre is the high strength, high stiffness form commonly used in composites. These are made by a complicated process from textile pre-cursor yarns made from either Polyacrylonitrile (PAN) or pitch that results in a predominantly graphitic structure highly oriented in the direction of the fibre axis. This high orientation gives them their remarkable properties which include a small negative coefficient of thermal expansion in the axial direction as well as remarkably high specific strength and stiffness.

This material data has been provided by Matmatch.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
