Presumably you mean bat WING skin?
Swartz, S. M., M. S. Groves, et al. (1996). "Mechanical properties of
bat wing membrane skin." Journal of Zoology 239: 357-378.
Uniaxial tensile tests w.r.t. main fibre orientation and area of
wing. Fibre bundles have core of elastin fibres with a sheath of
collagen fibres (orientation of collagen undefined). There are also
muscles between bone and membrane fibres and between the membrane
fibres only. Failure strain varied from 0.13 to 2.32; modulus from 1
to 200 MPa; strength from 21 to 0.1 MPa. All clearly vary strongly
with orientation to the direction of corrugation (though not fibre
angle, suggesting that the fibres generate a non-uniform field of pre-
strain) although there is a large amount of scatter. Correlations
are presented as log (E, strength or max. strain) vs. corrugation
angle (0 to 90).
