摘要:
A layered product which is a molded object comprising a thermoset resin layer, a thermoplastic resin layer, and reinforcing fibers comprising many continuous filaments, wherein the thermoset resin layer has been united with the thermoplastic resin layer at the interface between these layers, the resin of the thermoset resin layer and the resin of the thermoplastic resin layer each having an irregular surface shape at the interface, and a group of filaments among the reinforcing fibers are in contact with at least the resin of the thermoset resin layer and the other group of filaments among the reinforcing fibers are in contact with at least the resin of the thermoplastic resin layer, that side of the thermoplastic resin layer which is opposite to the interface being a surface of the molded object.

摘要:
The invention relates to a porous membrane having excellent durability and being useful as an ultrafiltration membrane, which substantially comprises a phenylene sulfide copolymer represented by the formula (-Ph-S-) m (-Ph-X-) n and which has a nonuniform structure wherein a dense layer or layers substantially governing the separating function of the membrane are formed on one side or both sides of the membrane and a porous layer having a larger void volume is formed in contact with said dense layer. In said formula Ph represents a phenylene group, X represents -SO₂, - or-CO-, and m and n each represents a natural number.
摘要:
An FRP molded article molded by hot runner injection molding with a mixture of thermoplastic resin and reinforcing fibers of 0.1 - 7 mm in average length dispersed in the thermoplastic resin; and a hot runner injection molding method therefore. The molded article is preferable for use as a housing for electronic terminal equipment, cellular phones, etc.
