Experimenal study on the parameters affecting the bending behavior of composite plates

الملخص EN

In this paper the bending behavior of composite plates manufactured from polyester reinforced with fiberglass, jute fiber and eggshell powder is studied .The moisture effect on the plate bending behavior is investigated by immersing the specimens in salt water and distilled water for 7 days.

Also the effect of type of edges fixture on the central displacement of the plate is investigated.

The results showed that for the fiberglass composite plates the central displacement for the moist specimens is 3-4 times as that for dry specimens.

For the eggshell powder composite plates, it is found that the stiffness of the dry specimens is greater than that of moist specimens by about three times.

The moisture absorption shows no significant effect on the stiffness of the jute composite plate.
