Abstract
The development of using composite materials is continuously increasing in
everyday commodities like furniture, bath tubs, railings, civil, electrical goods, sports
equipment, aerospace, wind turbine; cars etc. and ship industry also started using
composites initially for some of the parts and later on for the whole structure.
Recently, there has been a growing interest in the use of green composite material
obtained from renewable resources because advantages of these components include their
low production cost, in some cases, and their possible biodegradability which a new
category of composite was known as green composite material.
In this work, composite fabrication was produced to give better fabrication
performance by hand lay up manufacturing method.
Determination both of the optimum type of the matrix and the matrix formula were
carried out to give better fabrication performance. Different textile preforms were
fabricated at different weight fractions with different properties towards wider
technological applications. Several experiments were carried out to investigate the textile
composite failure due to the existence of voids which were made artificially with the
different parameters such as; distribution, size, and void percentages. It was found out that
textile reinforced composite (e.g. woven fabric) can withstand higher percentage of voids
than other composite materials.
An experiment of determination of the fabric intersection factor was carried out to
support the study of the theoretical stress model of woven fabric reinforced composite
production.
Wind turbine blade has successfully been manufactured using green composite
material. Flax fabric has been used as it’s almost similar to the glass fiber properties
noticing that flax has lower density as well as flax fibers are friendly for environment. The
inclusion of carbon fibers doubled the tensile strength, bending rigidity and compression
strength.
