lzO+)-Silica (SiO□)-based glass fiber, which uses a blowing method in which raw materials whose main components are alumina and silica are melted and blown using a high-speed stream of steam or air, and the centrifugal force of a rotating disk is used. Typical types manufactured by the spinning method, the EFG method that applies a capillary mechanism, etc. are the standard type in which the raw material composition weight ratio (AbOi:5iOz) of ceramic fiber is 50% = 50%, 60% = 40%. Examples include high temperature type and 95%:5% ultra high temperature type.

% and the aromatic polysulfone resin is less than 30 wt%, it is not preferable because the melt fluidity of the resin composition decreases. On the other hand, if the total amount of glass fibers and ceramic fibers is less than 10 wt%, it is sufficient. No reinforcing effect can be obtained.

Even if it is 0 to 70 wt%, if the amount of glass fiber is less than 51%, the resulting resin composition will have insufficient rigidity,
If the amount of ceramic fibers is less than 5 wt%, the molded product will exhibit significant anisotropy, and the thin portions will lack rigidity, making it impossible to obtain sufficient smoothness on the surface of the molded product.

Due to the large difference between the two, mixing becomes insufficient and a uniform resin composition cannot be obtained.
