Abstract
This study investigates in the mechanical properties of composites materials
which is used in the manufacturing of pipelines.
Two types of binary blends for the matrix materials consisting (Epoxy-10%,
15%, 20% Resole) and (Epoxy- 2%, 4%, 6% Polysulfide rubber) were prepared, then
both two blends were tested mechanically with (tensile, hardness, impact and
flexural) and the best mechanical properties were for the blends of (90% Epoxy-
10% Resole) and (98% Epoxy- 2% Polysulfide) which are chosed to be reinforced
it in the next stage.
Two types of fibers (carbon fibers, glass fibers) with one weight fraction (20%)
were used to reinforce the best percentage for both types of binary blends. Fibers
were used to reinforce composites materials with four types of reinforcement as:
reinforced matrix with three layers of carbon fibers, reinforced matrix with three
layers of glass fibers, reinforced matrix with two layers of carbon fibers and one
layer of glass fibers (carbon, glass, carbon) and reinforced matrix with two layers of
glass fibers and one layer of carbon fibers (glass, carbon, glass). Various mechanical
tests were carried out on test samples: tensile, impact, hardness, bending and wear,
as well as the physical test (absorption test). The results of all reinforced hybrid
composites showed an increase in all mechanical properties. The obtained results
determined the best composite material blend that suitable for the manufacturing of
pipelines applications after comparing the properties of hybrid composite blends
with materials used for manufacturing pipe where the sample was which reinforced
by three layers of carbon fibers for (Ep- 2% Ps) blend has the best mechanical
properties
