Term: carbon fibres type LM
https://doi.org/10.1351/goldbook.C00836

Definition:
Carbon fibres type LM (low modulus) are carbon fibres with isotropic structure, tensile modulus values as low as 10% of the C11 values of the graphite single crystal, and low strength values.

Note: The term carbon fibres type LM is sometimes used for various types of @I03354@ fibres known as @P04678@ or @R05161@ that have not been subjected to hot-stretching. Such fibres are not used for reinforcement purposes in high-performance composites.
