Mechanical and Impact Properties of Packaging-Waste/E-Glass/Epoxy Sandwich Composites for Construction Applications
Öz
Using textile structural
composites improves day by day in various industries due to their high specific
strength and modulus, good fatigue and corrosion resistance. The most important
reasons for the increased use of textile structural composites are the increased
expectations for product performance and demand for lightweight materials in
global markets. Rapid economic growth, urbanization, rising in population and
welfare level lead to an increased amount of waste production. In Turkey, the
annual average of solid waste is 25 million tons and 20% of this waste consists
of packaging waste. In this study, a new sandwich material was developed for
construction applications with low cost and high performance by using box
wastes as core and E-Glass woven fabric as sheet materials. The mechanical
properties were investigated by 3-point bending test and their impact behavior
was compared after low-velocity impact tests in different energy levels. The
core material had a negligible bending strength. The bending load of sandwich
composites was dramatically higher than those of face material. Low-velocity
impact results showed that absorbed energy and damaged area increased with
increasing impact energy level. It could be concluded that the developed
sandwich composites absorb more energy with small damaged areas and therefore
can be considered as damage resistant materials for constructional applications
as door and siding. The thermal insulation properties of these new sandwich
composites will be also investigated in future researches.
