Preferred Label : carbon fibres type IM;
IUPAC acronym : IM; HT;
IUPAC definition : Carbon fibres type IM (intermediate modulus) are related to carbon fibres type HT
because of the comparable values of tensile strength, but are characterized by greater
stiffness (Young's modulus up to approximately 35% of the theoretical C11 value).;
Scope note : the tensile modulus (young's modulus) varies between ca. 275gpaand 350gpa, but the
disposition of the boundaries is somewhat arbitrary. the relatively high ratio of
tensile strength to tensile modulus, typically above 1 10-2, in carbon fibres type
im, in spite of an increase of young's modulus, requires a further increase of strength,
which is achievable by a significant reduction of the monofilament diameter down to
about 5µm. such small filament diameters are typical of carbon fibres type im.;
