Abstract

[과제][assignment]

레진 트란스퍼 성형법(RTM)등의 유리섬유강화 플라스틱의 크로즈드시스템 성형법에 있어서, 성형형에 도입하여 세트하고 매트릭스 수지를 주입하였을 때 유리섬유가 쏠리지 않고, 더욱이 주름이 발생하지 않고, 균일한 두께를 갖고, 또한 균질한 FRP 성형품을 얻을 수 있는 유리섬유 프리폼을 용이하고 안가하게 제조할 수 있는 방법을 제시한다.In a closed system molding method of glass fiber reinforced plastics such as resin transfer molding method (RTM), glass fibers do not squeeze when the matrix resin is introduced and set in the molding die, and wrinkles are not generated, and uniform thickness is achieved. The present invention also provides a method for easily and inexpensively producing a glass fiber preform capable of obtaining a homogeneous FRP molded article.

[해결수단][Resolution]

유리섬유 프리폼의 제조방법은 유리섬유에 공기경화형 불포화 폴리에스텔수지 원료, 경화제, 경화촉진제 및 유기용제로 이루어지는 바인더 조성물을 부착시키고, 이어서 바인더 조성물의 불포화 폴리에스텔수지를 경화시켜서 유리섬유를 수지로 일체로 결합시켜 유리섬유 프리폼을 형성한다.The manufacturing method of the glass fiber preform is to attach a binder composition composed of an air-curable unsaturated polyester resin raw material, a curing agent, a curing accelerator, and an organic solvent to the glass fiber, and then curing the unsaturated polyester resin of the binder composition to integrate the glass fiber into a resin. To form a glass fiber preform.
