Studying the effect of polymer powders on some mechanical properties of epoxy

Abstract EN

To determine the possibility of using polymer powders as reinforcing materials in the thermoset polymer matrix composite, epoxy as the matrix and carboxy methyl cellulose (CMC) and polyethylene glycol (PEG 4000) as the reinforcing powders were used to prepare a particle reinforced composite.

In the sample preparation, seven weight fractions of each powder (0.02, 0.04, 0.06, 0.08, 0.1, 0.12, 0.14) wt % were designed to determine the mechanical properties of composites that represented by hardness and compression strength.

The results of this research were: for epoxy reinforced with CMC, the hardness increases with increasing the weight fractions reaching to (78.2) at 0.1 wt % and decreases in other weight fractions while maximum compressive load (7.324kN) was obtained at 0.12wt %, for epoxy reinforced with PEG4000 the hardness increases with increasing the weight fractions reaching to (71.1) at 0.06wt % and decreases in other weight fractions while maximum compressive load (10.449 kN) was obtained at 0.08 wt %.
