Leak Before Burst

Leak Before Burst


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

Netting Analysis of CPVs

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 ...

Why Carbon Fiber?

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
