Abstract An issue of major concern in the utilization of laminated composites based
epoxy resin is associated with the occurrence of delaminations or interlaminar cracks,
which may be related to manufacturing defects or are induced in service by low-velocity
impacts. A strong interfacial filament/brittle epoxy resin bonding can, however, be combined
with the high fracture toughness of weak interfacial bonding, when the filaments
are arranged to have alternate sections of shear stress. To improve this drawback of the
epoxy resin, UV-thermal dual curable resin were developed. This paper presents UV-thermal
dual curable resin which were prepared using epoxy acrylate oligomer, photoinitiators,
a thermal-curing agent and thermoset epoxy resin. The UV curing behaviors and characteristics
of UV-thermal dual curable epoxy resin were investigated using Photo-DSC, DMA
and FTIR-ATR spectroscopy. The mechanical properties of UV-thermal dual curable epoxy
resin impregnated CF prepreg by UV curable resin content were measured with Tensile,
Flextural, ILSS and Sharpy impact test. The obtained results showed that UV curable resin
content improves the epoxy toughness. |
