とができる。[Effects of the Invention] The method for molding the vinylidene fluoride polymer composition of the present invention is such that even if the vinylidene fluoride polymer is blended with ordinary glass fibers and processed, the glass fibers do not absorb the heat of the vinylidene fluoride polymer. Since it does not accelerate decomposition, there is no risk of explosively generating highly toxic hydrogen fluoride gas, and it can be molded safely.

である。Furthermore, since inexpensive ordinary glass fibers can be blended with the vinylidene fluoride polymer, this method is economically extremely advantageous compared to the conventional method of blending carbon fibers.
