Title:
MOLDING MATERIAL AND ITS MOLDED ARTICLE
Document Type and Number:
Japanese Patent JPH0593078
Kind Code:
A
Abstract:
PURPOSE:To obtain a molding material providing light-weight molded articles having excellent mechanical strength by sandwiching a specific fiber reinforcing material between a coated surface of a film covered with a specific resin composition and a film not coated with the composition. CONSTITUTION:A fiber reinforcing material (e.g. chopped strand comprising glass fibers or aramid fibers, nonwoven fabric, etc.) is sandwiched between a coated surface of a film covered with a thermosetting resin composition containing a hollow filler (e.g. GMB or shirasu balloon) having preferably 20-65mu number-average particle diameter, 0.3-0.8 true specific gravity and closed cells and a film not coated with the resin composition and a liquid component of the resin composition is impregnated into the fiber reinforcing material to give the objective material. Two sheets of the materials are prepared, the films coated with the composition are previously removed from the two sheets of the materials, the surfaces from which the films are removed are superimposed, then films not coated with the compositions are removed and the resulting material is pressurized and compressed and cured to give a molded article.
