Epoxy is a thermoset synthetic product which is formed
from two different chemicals, namely polyepoy resin reaction with
hardener. In general, this type of epoxy material is widely used as
a fiber composite matrix, adhesive and coating. The purpose of
this study was to determine the effect of filler volume fraction on
water absorption capacity and mechanical strength (tensile
strength and bending strength)
The main ingredients of this research are filler (fly ash and
cement), epoxy resin and epoxy hardener. The volume fraction
varied by 5%, 15% and 25%. Composite making was done by
mixing filler with epoxy matrix. Mixing is done using a modified
mixer for 2 hours so that the mixture is even or homogeneous.
This mixture is mixed again with resin hardener and stirred for 3-4
minutes. Then it is vacuumed for 25 minutes and the mixture is
put into the prepared mold. After that, water absorption testing,
tensile test (ASTM D638) and bending test (ASTM D790) were
carried out.
The results showed that the equilibrium water content
from the highest to the lowest epoxy with cement filler 25%,
cement 15%, cement 5%, fly ash 25%, fly ash 5% and fly ash
15% respectively 17.49% , 12.69%, 7.92%, 7.10, 7.10, 6.96. The
mechanical properties of epoxy (elastic modulus, tensile strength
and bending strength) decrease in wet conditions, but elongation
when broken is increased due to more tenacity. In general, tensile
strength and bending strength of specimens in dry and wet
conditions tend to decrease with increasing filler volume fraction.
Addition of the filler volume fraction to epoxy increases the tensile
and bending modulus of elasticity. |
