、製造コストが高くなるという問題がある。The scrap binder molded product has a high layer density, so the specific gravity of the molded product is high, and the processing strength is low, so that it is easy to break when bent into a shape corresponding to the installation part. Therefore, by bonding and reinforcing the tip of the scrap binder molded product with a reinforcing material made of a low-density foam with a small specific gravity via adhesive, the specific gravity of the entire molded product can be reduced, and the processing strength can be increased. Although it is possible to improve this, there is a problem in that the work of adhering the scrap binder molded product and the reinforcing material made of the low-density foam is complicated and the manufacturing cost increases.

At the same time, this mixture is bonded with a binder resin and the scrap binder molded layer is molded, so that the scrap binder molded layer and the low-density foam layer are integrally joined through the above-mentioned engaging portion ( This is what I did.

), upwardly expanding protrusions 1 are formed on the surface at predetermined intervals, and dovetail-shaped engaging portions 2 are formed between the protrusions 1.
A low-density foam layer 3 having a thickness of about 10 ma+ is formed. In culm (b), in order to remove shrinkage deformation, etc. that occurred when cooling the low-density foam layer 3 taken out from the mold to room temperature, the low-density foam layer 3 was

に連結される。Next, in step (C), after the low-density foam layer 3 is placed in the lower mold 4 of the pressure molding mold, the mixture 5 containing fiber waste, synthetic resin material layer, etc. is heated. The surface of the low-density foam layer 3 is filled with a resin mixed with a binder resin material 6 made of a curable resin solution or the like. and step (d)
In -L&! Insert the pressure part of the inner mold 7 into the hand mold 4 and pressurize the mixture 5, etc. into the pressure molding mold 130.

Molded scrap binder about 10 shoes thick on the surface of l148
molded into one piece. During molding of this waste binder molding layer 8, the mixture 5 and binder resin 6 infiltrate into the engaging portion 2 of the low-density foam layer 3, and upwardly widening protrusions 9 corresponding to the engaging portion 2 are formed. Therefore, the waste binder molded layer 8 and the low-density foam layer 3 are integrally connected via the engaging portion 2.

工程を終了する。Next, in step (e), the upper mold 7 is released from the lower mold 4 and the lower mold 4 is separated into left and right sides, thereby forming a composite formed of the scrap binder molded layer 8 and the low-density foam layer 3. The material 10 is removed from the pressure molding die to complete the manufacturing process.

を効果的に補強することができる。In this way, on the surface of the low-density foam layer 3 on which the engaging portion 2 is provided, a waste binder molding layer 8 consisting of a mixture 5 of fiber waste and a synthetic resin material layer, and a binder resin material 6 is formed. Since the scrap binder molding layer 8 and the low-density foam layer 3 are integrally connected via the engaging portion 2, the scrap binder molding layer 8 and the low-density foam layer 3 are integrally connected to each other via the engaging portion 2, without using an adhesive or the like. A composite material 10 in which 8 is reinforced by a low density foam layer 2 can be easily manufactured. That is, at the same time as the scrap binder molding layer 8 is pressure-molded, the material that has entered the engaging portion 2 of the low-density foam layer 3 forms the protrusions 9 of the old binder molding layer 8, and these protrusions Since the strips 9 and the protruding strips 1 of the low-density foam layer 3 constituting the engaging portion 2 are engaged with each other, the strips 9 and the protruding strips 1 of the low-density foam layer 3 constituting the engaging portion 2 are engaged with each other. Scrap binder molding F! 8 and the low-density foam layer 3 are mechanically bonded to each other.

合材１０の比重を小さな値にすることができる。Further, the low density foam layer 3 usually has a specific gravity of 0.0.
35, which has an extremely low specific gravity compared to the scrap binder molding layer 8 which has a specific gravity of around 0.3 to 0.4, so this scrap binder molding layer 8 and the low density foam layer 3 are integrally joined. By forming the composite material 10 in this manner, the specific gravity of the composite material 10 can be reduced to a small value.

層８との接合強度が著しく低下することになる。In addition, after molding the low-density foam layer 3, which tends to undergo shrinkage deformation after molding, the scrap binder molding Fy:I8, which is relatively hard to cause shrinkage deformation, is pressure-molded on top of the low-density foam layer 3. The waste binder molding layer 8 and the low-density foam layer 3 can be firmly joined through the bonding layer 2. That is, as shown in step (a) of FIG. 2, after molding the scrap binder molding layer 8 having the engaging portions 11 on the surface, in step (b), the scrap binder molding layer 8 is placed in a molding die. It is also possible to mold the low-density foam layer 3 by filling the foamed resin from above, but in this case, in step (C), the low-density foam layer 8 is cooled after molding. When the air bubbles inside are crushed, the low-density foam layer 3
shrinks and deforms. As a result, the protrusions 12 of the low-density foam layer 3 filled in the engaging portion 11 contract,
A gap is formed between the protrusion 12 and the engaging portion 11, which significantly reduces the bonding strength between the low-density foam layer 3 and the waste binder molded layer 8.

接合強度が低下することはない。On the other hand, in the case where the scrap binder molding layer 8 is pressure-molded after the low-density foam layer 3 is molded as described above, after the scrap binder molding layer 8 is molded, Since this scrap binder molding layer 8 does not shrink and deform, it is possible to prevent a gap from being formed between the engaging portion 2 of the low density foam layer 3 and the protrusion 9 of the scrap binder molding layer 8. The bonding strength between the scrap binder molded layer 8 and the low-density foam layer 3 does not decrease.

For example, as shown in FIGS. 3 and 4, when molding the low-density foam layer 3, an engaging portion 2 consisting of a circular hole expanding downward may be provided, or as shown in FIG. As shown in FIG. You may also do so. Further, as shown in FIG. 6, an engaging portion 2 consisting of a long hole expanding downward, or a square hole expanding downward as shown in FIG.

A composite material 1° consisting of scrap binder molding layers 8, 8 covering both the front and back surfaces of the composite material 1° is manufactured, and the scrap binder molding layers 8,
8 are connected to each other via a communication part 13 formed in the engaging part 2 of the low-density foam layer 3, whereby the scrap binder molding layers 8, 8 are integrally joined to both the front and back surfaces of the low-density foam layer. Therefore, even if some gap is formed between the engaging portion 2 and the communicating portion 13, there is no risk that the bonding strength will decrease.

The mixture 5 can be effectively combined without applying pressure.

安価に製造することができるという利点がある。As explained above, the present invention involves molding a scrap binder molding layer on a low-density foam layer provided with an engaging portion, thereby connecting the scrap binder molding layer and the low-density foam via the engaging portion. Since the body layer is configured to be integrally bonded to the body layer, it is possible to reinforce the 6 binder and molding layers with the low-density foam layer without the need for complicated bonding work using adhesives, and to reduce the specific gravity. There is an advantage that a small composite material can be manufactured easily and at low cost.
