26.0 % and 6.9 %, respectively. Therefore, the density of the laminates becomes one
of the predominant factors that influence the specific properties of the hybrid materials
and it is possible to consider it as one of the criteria in selecting the types and forms of
reinforcements. Hence, it is very crucial in designing and creating the composite
structures, particularly when the application is highly concerned on the strength to
weight ratio.
