Delamination is a mode of failure for composite materials and steel. In laminated materials, repeated cyclic stresses, impact, and so on can cause layers to separate, forming a mica -like structure of separate layers, with significant loss of mechanical toughness.

Water-ground Phlogopite micas were classified into narrow particle-size distributions containing flakes with well-defined diameters and thicknesses in order to evaluate the influence of particle size and flake aspect ratio on the mechanical properties of mica-filled polypropylenes, For the purposes of comparison, most of the injection-molded specimens contained 40 percent (by weight) mica.

Bandgap engineering of atomically thin 2D crystals is critical for their applications in nanoelectronics, optoelectronics, and photonics. Here, we report a simple but rather unexpected approach for bandgap engineering of muscovite-type mica nanosheets (KAl3Si3O10(OH)2) via controlled molecular thickness. Through density functional calculations, we analyze electronic structures in 2D mica ...

The first loss of water at 500 °C was attributed to the presence of interstratified mica as the dehydroxylation of the interstratified mica layers in vermiculite was reported in the range of 550–575 °C (Justo et al., 1993).

A delamination acts like a high thermal resistance that reduces the ability of an IC package to act like a heat sink, so a delaminated die can overheat. A large or growing delamination worsens this effect and the die may eventually overheat to the point that it fails.
