Ultimate stress decreased with the increasing temperature, particularly for temperatures exceeding 400[degrees]C, while the strain corresponding to the peak strength increased with temperature.
The filler-matrix bonds act as extra crosslinks at the interfaces of the composite materials, improving the matrix-fiber adhesion, giving more compact structures (density section) as well as enhancing the mechanical properties, modulus and ultimate stress. TABLE 1.
From these results it is clear the reduction in the ultimate stress and ultimate strain when the number of cycles fatigue increases for the both laminates.
