In contrast to steel volute casing, the strength and stiffness of the volute casing made of PMMA or other engineering plastics must be taken into consideration because these materials have smaller allowable stress and are more deformable.
The material of volute casing is PMMA.
It can be found that when the rotational speed is 1690r/min, the maximum stress of volute casing is 62.5MPa, which is equal to the allowable stress of the material PMMA.

The studies carried out in the last few years about materials of concrete have emphasized that the use of reinforcing fibers with adequate dosage by volume of concrete improves the behavior of composite members and reduces its brittleness. [2] This paper presented an experimental investigation on the axial compressive behaviour of hollow welded steel stud columns, with square cross-section, filled with plain normal strength concrete, plain high strength concrete or steel-fiber reinforced high strength concrete.
Geometric and material properties of specimens.
In order to determine the actual material properties in compression, steel stub column were conducted.

Therefore, L-aspartic acid(LASP) as a natural material by adding into AA-AM is to improve the absorb-water performance, salt-resistance performance and biodegradability of AA-AM polymer, which has important scientific value to promote the engineering applications of SAP[10].
PASP was enriched crosslinking density gradients and hierarchical porous material, which had very strong water absorbency and poor hydrogel strength.
