Mechanical Properties of Boron and Kevlar-49 Reinforced Thermosetting Composites

چکیده
Glass reinforced thermosetting composite materials are now widely usUUed in building and construction applications. However, the adoption of Boron and Kevlar based composite materials in this industry has been very slow, and the main reasons are lack of previous experiences to assess the durability of such composite products and understanding of their properties by designers. In order to fill this gap, the understanding of Boron and Kevlar fibre reinforced thermosetting composites becomes necessary for the design of structures. This study is aimed towards characterizing the mechanical properties of four selected reinforced composites using these fibres to benefit designers and manufacturers in a direct and an easily understandable manner. The properties of these composites were evaluated using micromechanics models based on classical lamination theory, self-consistent approach and Rosen and Xu-Refsnider models. The model estimations are compared with the experimentally obtained mechanical properties. An attempt is made to rationalize the results with respect to the basic properties of the constituents of these composites so that newer composites can be confidently estimated.
