Austria Linz Chemical Company built the first factory of the sulfuric acid and cement production taking the phosphogypsum as raw material in 1969 [4].
The sulfuric acid process producing directly by the reaction coupling method is mainly that the calcium sulfate and related materials dissociate the sulfate radical ion in the liquid phase, couple with the separation process at the same time, let the sulfate timely separate and combine with the hydrogen ions, and form the sulfuric acid.

Most of these have been confined to isotropic materials solid beams [2-6], for example.
On the other hand, the amount of work carried out on thin-walled beams made of composite materials has been rather limited.
