Disclosed is a composite panel for an automotive interior material with a double-engaged structure. According to the present invention, the composite panel for the automotive interior material with the double-engaged structure comprises: a synthetic resin panel made by an injection molding to form a shape on one side inside an automobile; a metallic reinforcing bracket which partially reinforces one area of the synthetic resin panel by being inserted into a mold; first engagement injection units which, when the injection molding of the synthetic resin panel is conducted, are introduced into a plurality of engagement holes formed on the central unit of the reinforcing bracket to form an engagement force with the reinforcing bracket; and one or more second engagement injection units which, when the injection molding of the synthetic resin panel is conducted, are made to wrap around some edges of the reinforcing bracket and to form an engagement force with the reinforcing bracket. According to the present invention, the plurality of first engagement injection units, which form an engagement force in a certain shape with the central unit of the reinforcing bracket inserted when the injection molding is conducted on the synthetic resin panel, and the one or more second engagement injection units, which form an engagement force in a certain shape with some edges of the reinforcing bracket, are formed integrally with the synthetic resin panel and the reinforcing bracket not only to reinforce a strength of the synthetic resin panel′s own but also to strengthen an engagement force between the reinforcing bracket and the synthetic resin panel, thereby reducing an allophone, damage, and separation even when there is an impact or vibration.

    이중결합구조의 자동차 내장재용 복합패널이 개시된다. 본 발명에 따른 이중결합구조의 자동차 내장재용 복합패널은, 자동차의 내부 일측의 형상을 구성하기 위해 사출성형되는 합성수지패널; 금형 내에 인서트되어 상기 합성수지패널의 일영역에 대한 부분적인 보강이 이루어지도록 하는 금속재 보강브라켓; 상기 합성수지패널의 사출성형시 상기 보강브라켓의 중앙부에 형성된 다수의 결합홀 내로 유입되어 상기 보강브라켓과 결합력을 형성하는 제1 결합사출부; 및 상기 합성수지패널의 사출성형시 상기 보강브라켓의 일부 테두리를 둘러싸도록 이루어져 상기 보강브라켓과 결합력을 형성하는 하나 이상의 제2 결합사출부를 포함하는 것을 특징으로 한다. 본 발명에 의하면, 합성수지패널의 사출성형시 인서트되는 보강브라켓의 중앙부와 소정의 형상으로 결합력을 형성하는 다수의 제1 결합사출부 및 보강브라켓의 일부 테두리와 소정의 형상으로 결합력을 형성하는 하나 이상의 제2 결합사출부가 합성수지패널 및 보강브라켓과 일체로 형성됨에 따라, 합성수지패널 자체의 강성이 보강됨은 물론, 보강브라켓과 합성수지패널 간 결합력의 강화로 인해 충격이나 진동에도 이음발생이나 파손 내지 분리 등이 저감될 수 있다.
