Abstract: Provided is a battery case for an electric car. The battery case includes a support part configured such that a battery module is seated and supported and including a sidewall extending upwards from an edge portion thereof, an inner frame coupled to a top surface of the support part to partition a seat part of the battery module, and an outer frame coupled to an outer surface of the support part.

Abstract: Provided is a lower protecting plate of a battery module for an electric car. The lower protecting plate may include a fiber-reinforced plastic composite formed of a lamination sheet including at least one of first and second sheets. The first sheet may include matrix resin and reinforced fiber in the form of long fiber. The second sheet may include matrix resin and reinforced fiber in the form of fabric woven by continuous fiber.

Abstract: The present invention provides a CFT pre-forming insert injection molded seat back frame. The CFT pre-forming insert injection molded seat back frame comprises: a pair of frame parts which are coupled to face each other and have fiber reinforced plastic formed therein; and reinforcement parts which are formed on regions that the pair of frames respectively face, and are coupled to each other in multiple locations.
