Abstract:
Different formulations of EPDM based composite were synthesized to
achieve a composition that gives best mechanical properties. Silica, alumina, ATH,
MDH, Kevlar chips, phenolic resin were used as reinforcements in EPDM. Woven
Kevlar fiber (armour grade), Nomex fiber, Silicon carbide coated woven Kevlar
fiber have been used to formulate the laminate structure with EPDM. Kevlar fiber a
product of Dupont, which has best mechanical properties in all fiber family and
EPDM, has low density and high shock absorbance properties. The composite with
woven Kevlar fiber gives good mechanical properties but silicon carbide coated
woven Kevlar fiber embedded in EPDM gives the best result regarding mechanical
properties. This composite has an impact strength of 303 KJ/m2 i.e. three times
more than mild steel; it has also high tensile strength i.e. 2190 Psi.
