ランスファ（移送）成形法で行われている。2. Description of the Related Art Conventionally, molding of an integrally molded product of a glass member or a ceramic member and a thermosetting resin is generally carried out by a transfer molding method.

を取り出し、二次加工、検査などを行い完成品となる。The outline of the molding method is as follows. First, a glass member or a ceramic member is set between the heated positioning molds having the lower mold cavity, and then a predetermined amount of thermosetting resin is put into the lower mold pot to close the upper mold and placed in the pot. Push in the thermosetting resin with a plunger. Next, the thermosetting resin that has passed through the runner flows into the cavity from the gate port and is cured by heat, so that an integrally molded product of a glass member or a ceramic member can be obtained. Then, after the curing is completed, the molded product is taken out from the mold and subjected to secondary processing, inspection and the like to obtain a finished product.

ている成分からなる。Conventionally, typical thermosetting resins used in the molded articles are unsaturated polyester resin, a low-shrinking agent, a curing agent containing a filler as a main component, a polymerization inhibitor, and an internal release agent. , A lubricant, a coloring agent, a thermoplastic elastomer, an azo-based polymerization initiator, a thickener, and glass fibers (chopped strands) as a reinforcing agent are added, and they are composed of generally known components.

硬化完了後の成形品の縦方向の反り量（δ＝２．８〜
３．４ｍｍ）が大きくなる。この反り量は、図３に示す
ものをいう。However, in the thermosetting resin having the above-mentioned formulation, the coefficient of thermal (linear) expansion is 4 to 5 times larger than that of the glass member (4.6 × 10 −6 / ° C.). ,
The amount of warp in the vertical direction of the molded product after curing is completed (δ = 2.8 to
3.4 mm) becomes larger. This amount of warpage refers to that shown in FIG.

ら必然的に熱硬化性樹脂の組成に限界がある。In order to reduce the amount of warp in the longitudinal direction, the amount of unsaturated polyester resin in the thermosetting resin, organic components such as a low-shrinking agent should be reduced and the amount of glass fiber added as an inorganic filler and a reinforcing material should be increased. However, such a thermosetting resin causes problems such as non-filling and defective appearance of the molded product, so that the value as a product cannot be obtained. Therefore, the composition of the thermosetting resin is necessarily limited.

2) Workability is poor during secondary processing,
3) In many cases, problems such as the need to arrange jigs and tools in order to correct warpage during assembly at the customer's site occur.

形品の反り量はδ4 ＝３．１ｍｍの値であった。[Example 4] A material in which the reinforcing material was replaced by a conventional glass fiber, that is, 8.3% by weight of carbon fiber was added to the glass fiber (chopped strand having an average fiber length of 3 mm, linear expansion coefficient: 3 x 10). -6 / ℃ ~ 5 × 10 -6 / ℃)
Compounding was carried out in the same manner as in Example 1 except that the amount was changed to 10% by weight (3.89% by volume) and the difference in the amount of aluminum hydroxide was reduced at a constant rate, and molding was performed using the same mold. As a result, the amount of warpage of the molded product was a value of δ 4 = 3.1 mm.
