Abstract:
To provide a resin molding and a method for producing the same.A resin molding in which two types of substrates differing in thermal shrinkage are connected together, wherein the thermal shrinkage of a connection part of the two types of substrates is a value between the respective thermal shrinkages of the two types of substrates. It is preferred that the connection part be constituted of an end part of any one substrate of the two substrates. More specifically, there can be adopted an embodiment in which one substrate is a plate-like substrate including reinforcing fibers and a first thermoplastic resin binding the reinforcing fibers to each other and the other substrate is an injection-molded member connected in the plate face direction of the one substrate, wherein the thermal shrinkage of the other substrate is large as compared to the thermal shrinkage of the one substrate. Moreover, the connection part can be formed by adjusting the filling density of reinforcing fibers in an end part of the one substrate to be lower than the filling density of reinforcing fibers in the base part of the one substrate.
