Abstract
The use of composites plays an important role in the fields of Mechanical and Civil
Engineering. The idea of using composite materials in the two afore mentioned fields
are no longer new. In the Fibre Composite Design and Development (FCDD),
University of Southern Queensland (USQ) many researches and experiments on new
lightweight materials and structures have been carried out. In the research, FCDD
found that the composites made from vinyl ester resins suffer considerable shrinkage
during hardening. With this issue in mind, research on the methods to decrease the
shrinkage of the composites had been carried out. Ku (2002) claimed that by having
vinyl ester composites cured under microwave conditions, such shrinkage can be
reduced. The material used was thirty three percent by weight flyash particulate
reinforced vinyl ester composite VE/FLYASH (33%). The purpose of this project is
to research, measure and compare the fracture toughness of vinyl ester composite
cured under ambient and microwave conditions by using the short bar test.
The specimens will then fractured by using the MTS 810 Material Testing Systems
and the value of fracture toughness was obtained through some calculations.
And finally the results will analyzed by using Latin Square, determine which
treatments were most effective in maintaining the fracture toughness while reducing
the shrinkage of vinyl ester composite, and by how much, and which are worthless, so
we can weight the economic alternatives.
