The present invention relates to a composition of a lightweight transparent composite material, a method for producing a composite material by using the composition, and a composite material produced through the same. In particular, a lightweight transparent composite material having excellent shock resistance, scratch resistance, weatherproofness, and high strength can be provided by thermally hardening a glass fiber reinforcing material (A) having a refractive rate of 1.4 to 1.6 and a hardening resin (B) having a difference in a refractive rate from the glass fiber reinforcing material, wherein the difference is -0.005 to +0.005. In particular, when the lightweight transparent composite material according to the present invention is applied to a transparent window of a vehicle, vehicle fuel efficiency is improved. Also, the center of gravity of a vehicle is lowered, so more smooth steering properties can be expected. Excellent strength of the material can improve trembling and shape stability when a vehicle is driven.

    본 발명은 경량화 투명 복합재료의 조성물, 상기 조성물을 사용한 복합재료의 제조 방법 및 그에 따른 복합재료에 관한 것으로, 구체적으로 굴절율 1.4 내지 1.6인 유리섬유보강재(A)와 이러한 유리섬유 보강재와 굴절율 차이가 -0.005 내지 +0.005인 경화성 수지(B)를 열 경화시킴으로써 내충격, 내스크래치, 내후성, 및 고강성이 우수한 경량화 투명 복합재료를 제공할 수 있다. 특히 본 발명에 따른 경량화 투명 복합재료가 자동차의 투명창에 적용하는 경우 자동차 연비향상, 차량 무게 중심이 낮아져 보다 민첩한 조향성을 기대할 수 있으면서도, 강성이 우수하여 자동차 주행 중에도 떨림 및 형태 안정성이 개선할 수 있다.
