Leak Before Burst

Since a composite pressure vessel (CPV) typically stores gas at high pressure, the design of the vessel structure needs to be treate...

Netting Analysis of CPVs

In the cylindrical section of a closed-end pressure vessel, the hoop or the circumferential stress is twice that of the axial stress. If a homogeneous material with isotropic properties is used to fabricate a pressure vessel, the material properties are effectively unde...

Why Carbon Fiber?

Consider a spherical vessel made out of isotropic material with strength $\sigma_u$ <img title="" src="https://cpvdesign.com/static/img/spherical_vessel.png" alt="" width="389" data-align="center"> <br></br> Wall thickness of the spherical pressure vessel is calculated from, $$ t = \frac{pR}{2\sigma_u} $$ Mass of the spherical shell, $$ M = 4\pi R^2 t \rho $$ Internal volume of the
