Abstract:
This thesis is the study of bending and interlaminate shear properties of sandwich panels assembled
from styrofoam and glass fiber cement composites. The sandwich panels made from 2-sides of glass
fiber mesh reinforced mortar cover on a foam core. There are 4 types of reinforced glass fiber mesh
1 layer, glass fiber mesh 2 layers, glass fiber and glass fiber composite with glass fiber mesh 1 layer.
The sandwich panels have 2 thickness 8 and 12 mm. Then curing the samples by chemicals for a
period of 28 days before testing. the bending moment was tested by 4-point bending method
following ASTM C393/C393M-06 standard to find the maximum loads of samples. The results,
showed that the maximum loads of samples reincefore glass fiber. There were loads at first crack
and maximum load was above the other load of samples. But after considering the volume ofglass
fiber with the maximum loads of each type found that the sandwich panels reinforce glass fiber
mesh 2 layers and reinforce glass fiber that gave similar maximum load approximate is 7,116 N and
7,285 N. But the volume of glass fiber is 18,444 mm and 60,733 mm3 which showed that the
volume of glass fiber used for reinforcing is different up to 3 times. And after considering sandwich
panels reinforce glass fiber mesh 1 layer and reinforce glass fiber composite with glass fiber mesh 1
layer showed that maximum load 6,263 Nand 6,495 N are similar. But the volume of glass fiber
reinforce in the samples is 9,222 mm3 and 46,422 mm which showed that the volume of glass fiber
used for reinforcing is different up to 5 times. Great alternative is to use in the industry.
