Influence of elevated temperatures on flexural strength of polysialate composite

Polysialate composites are a new class of high performance materials due to its excellent inherent high temperature resistance, low density and ease of manufacturing. These properties also suggest that polysialate composites have a high temperature resistance, environmental friendliness, light weight structures for both aerospace and motorsport applications. The foremost important requirements for these applications are a high temperature resistance, low density, good structural properties and ability to form complex geometries at low lead times. The polysialate matrix is based on polymineral resins, it allows manufacturing using conventional polymer composite lay-up, and also it allows for complex geometries to be fabricated. The most and widely used polysialate matrix materials are reinforced with silicon carbide fibres material will be used to study behavior of flexural strength over a representative temperature range. In addition to this, the results also provide the data required for the design of next generation high temperature structures. The three point bending test simulation analyses were performed according to ASTM standard on these polysialate composites. The simulation analysis results revealed that flexural strength of polysialate composites were stable over a representative temperature range 100°C to 600°C.
