剤や通常の接着剤を用いてもよい。The above-mentioned synthetic resin is mixed with the above-mentioned mixed fibers in the form of powder or solution, and is usually formed into a cotton layer having a basis weight of 80 to 200 g / m 2 and immediately formed into cardboard, polystyrene foam, hard felt, synthetic resin-impregnated polyurethane foam, etc. When the synthetic resin as a binder is laminated on both sides or one side of the base material and pressure-bonded simultaneously with molding the base material, it is cured by means such as heating at the same time as pressure-bonding. In this way, the reinforcing material is formed on both sides or one side of the base material. For the adhesion between the reinforcing material and the base material, the synthetic resin contained in the mixed fiber is extruded from the mixed fiber at the same time as pressure bonding and functions as an adhesive, so that an adhesive is not particularly necessary, but if desired, a hot-melt adhesive Or an ordinary adhesive may be used.

ラス繊維は補強材に剛性を与え、かつポリエステル繊維
の熱変形を抑制する。In the mixed fiber, the polyester fiber reduces the weight of the glass fiber, imparts flexibility to improve the moldability, and entangles well with the glass fiber to prevent scattering of the glass fiber pieces. Furthermore, polyester fibers are superior in heat resistance and toughness to other organic synthetic fibers and are inexpensive. Further, the glass fiber gives rigidity to the reinforcing material and suppresses thermal deformation of the polyester fiber.
