Carbon fibres type LM
(low modulus) are carbon fibres
structure, tensile modulus values as low as 10% of the
values of the graphite
single crystal, and low strength values.
The term carbon fibres type LM
is sometimes used for various types of isotropic carbon
fibres known as pitch-based
or rayon-based carbon fibres
that have not been subjected to hot-stretching. Such fibres are not used for reinforcement
purposes in high-performance composites.
