Porosity of carbon nanotube cement composite
WebApr 13, 2024 · Carbon nanotube-reinforced polymeric composite was developed for doubly curved micro-shell panel applications. The composite’s mechanical behaviour is studied with the deformation theory of shear in a curvilinear coordinate system mixed with the approach of the non-classical system [ 27 ].
