Abstract: Provided is a combined explosion-proof electromotor, which includes a body in which an interior space is formed and whose one end is open in an axial direction, a terminal box whose one end is open in the axial direction so as to face the open end of the body and in which a space is formed to hold terminal cables extending from the outside, and a middle plate that is disposed between the opposing ends of the body and the terminal box which are connected by separate fastening means and that includes terminal insertion holes through which ends of the terminal cables are inserted into the body.

Abstract: A long glass reinforced resin composite of the present invention may comprise two kinds of thermoplastic matrix resin (a1, a2) which have different viscosities and a long glass fiber (B). The method of preparing the long glass reinforced resin composite comprises preparing a LFT (Long fiber thermoplastic) master-batch composition by impregnating the long glass fiber (B) of continuous phase into the low viscosity thermoplastic resin (a2), and compounding the LFT (Long fiber thermoplastic) master-hatch composition with high viscosity thermoplastic resin. The long glass fiber reinforced resin composite of the present invention has excellent mechanical properties such as impact strength, tensile strength, and flexural modulus.
