| Summary: | Membrane technology has an important role in the separation process. Several
advantages offered by the membrane-based separation technologies such as ease of
scale up because it’s modularity. Another advantages are the low energy
requirement and environmental friendly because no chemical addition required.
Water treatment and natural gas are the most dominant membrane-based
separation processes
Membrane process in seawater desalination and separation of CO2 fromnatural
gas require high operating pressures. So it needs a special housing that can be
operated at high pressure. Metal is a suitable material for this application because
it has excellent mechanical strength. However, the major disadvantage of metal are
low corrosion resistance and large density. FRP (fiber reinforced polymer) based
composite materials is a potential alternative for this application. The advantages
of composite materials over metal are (1) beter corrosion resistance, (2) the
specific mechanical properties (per unit weight of the mechanical properties of the
material) is much higher than metal because of lower density and (3) the ease of
the fabrication process
The aim of this research are to study the effect of fabrication parameter and
polymer matrix to mechanical properties of FRP based membrane housing
produced. The fabrication parameter investigated are fiber orientation (30o
, 55o
,
and 80o
) and fiber volume fraction (53,33% - 80%). Polymer matrix used are
unsaturated polyester and epoxy
Experimental result shows that fiber orientation and polymer matrix type
significantly affect burst pressure value. On the other hand, the effect of fiber
volume fraction on burst pressure value is insignificant. Burst pressure value of
membrane housing is increase with the increase of winding angle until 55o
then
decrease drastically in winding angle of 80o
. This behaviour is observed in both
epoxy matrix and unsaturated polyester matrix. The level of shrinkage is small and
difference between eposy matrix and unsaturated polyester is insignificant.
