Resumen:
Many
fiber-reinforced polymers offer a combination of strength and modulus that are
either comparable to or better than many traditional metallic materials. Some
characteristic of this materials are low density, high strengthweight and
modulusweight ratios. For these reasons, fiber reinforced polymers have
emerged as a major class of structural materials and are either used or being
considered for use as substitution for metals in many weight-critical
components in aerospace, automotive, and other industries (Mallik P. K, 2007).
In
the specific case of aerospace industry, the materials used must meet
additional requirements such as dimensional stability, high stiffness and high
temperature resistance. Fire resistance and ablative composites are used in
nozzle turbine construction and other components of rockets and airplane engines,
exposed to very high temperatures. Carbon fiber reinforced composites are
indicated for these applications. In turn, to achieve the necessary
standards of mechanical properties, it is essential to ensure a
minimum content of bubbles in the material. The best
technique for this is the processing by autoclave (Advani and Sozer,
2003).
The
main objective of this work was to obtain phenolic resin-carbon fiber composite
materials, and to characterize their mechanical properties and fire resistance.
Nanoclays were added to phenolic resins in order to evaluate their effect on the
fire performance of the composites.
