Samsung's tow prepreg
Uniform resin content, high heat resistance, high toughness! Capable of molding high-quality CFRP and GFRP.
"Tow Prepreg" refers to a bundle of fine carbon fibers or glass fibers called "tow," which is impregnated with resin and heated to maintain a state of tackiness at the B-stage (when the resin is partially cured). This intermediate material can be shaped into forms such as pipes and plates through dry filament winding molding that does not use resin. Our company offers prototype support using the fibers and resins of your choice. Please feel free to contact us with your requests. 【Features】 ■ Higher heat resistance, toughness, and quality compared to FW molding ■ A wide range of resin options available since the resin is diluted with solvent to adjust viscosity ■ Stable products can be produced with consistent resin content (R.C.) and fiber content (Vf) ■ Prototype support is also available using the fibers and resins of your choice *For more details, please refer to the PDF materials or feel free to contact us.
