An aromatic amine cured epoxy resin formulation system has been developed according to the characteristic
of the domestic aramid fiber. The curing process of the formulation system was studied by DSC test. Mechanical
property of the resin casting body was measured by universal testing machine. The interlaminar shear strength (ILSS)
of NOL-ring samples and explosion properties of Φ150 mm standard pressure vessels prepared by the domestic aramid
fiber reinforced aromatic amine cured epoxy composite were also investigated. The results indicate that the epoxy formulation
system provide excellent mechanical properties and heat-resistance performance. The tensile strength,elongation
rate at break,flexural strength and martin heat resistant temperature of the casting body are 101 MPa,4. 1%,177
MPa and 142. 2℃ respectively. The interfacial adhesion property of the composite is pretty good. The ILSS of the composite
and PV / W of Φ150 mm pressure vessels are 52. 1 MPa and 38. 44 km respectively.
