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.

Intermediate material "Tow Preg Preg"
It is possible to mold high-quality CFRP and GFRP! Intermediate materials that maintain a state of adhesion.
"Tow Prepreg" is an intermediate material that maintains a state of B-stage (partially cured) tackiness by bundling fine carbon fibers or glass fibers, referred to as "tow," and impregnating them with resin before heating. By using TP for dry FW molding, it becomes possible to mold high-quality CFRP and GFRP with uniform resin content, high heat resistance, high toughness, and high strength, compared to conventional FW molding. 【Features】 - An intermediate material that maintains a state of B-stage tackiness - Uniform resin content (R.C.) compared to conventional FW molding (wet process) - Capable of molding high-quality CFRP and GFRP with characteristics such as high heat resistance, high toughness, and high strength *For more details, please refer to the PDF document or feel free to contact us.

Oxide matrix fiber-reinforced ceramics (CMC) prepreg
It can provide tackiness with a special adhesive and excels in the moldability of complex shapes.
We manufacture custom orders of oxide matrix fiber reinforced ceramics (CMC) prepregs. The oxide matrix fiber reinforced ceramics (CMC) prepregs are environmentally friendly, water-based, and can be fired in the air. Additionally, they maintain high strength and damage tolerance even in oxidizing atmospheres. Forming thin-walled fiber reinforced ceramics is also easy. 【Features】 ■ Multi-layer structures of CMC can be easily formed through lamination. ■ Can be formed with silicon carbide fibers (SiC) or alumina fibers (Al2O3). ■ Can be formed with various types of fiber fabrics (plain weave, satin weave, twill weave) (unidirectional materials <UD> are also supported). ■ Compatible with fibers from both domestic and international fiber manufacturers. ■ Short fiber or non-woven fabric reinforced ceramic prepregs are also available. *For more details, please download the PDF or feel free to contact us.

Thermosetting resin prepreg "ENDUREDGE"
This is a thermosetting prepreg that can be stored at room temperature, reducing void formation and achieving a good appearance! It allows for a reduction in man-hours and costs throughout the entire molding process.
"ENDUREDGE" is a thermosetting prepreg that reduces void formation and achieves a good appearance. The design of the prepreg, which allows for easy gas permeability, reduces the occurrence of surface pinholes and internal voids, resulting in an excellent appearance even in out-of-autoclave molding. Since it can be stored at room temperature, it solves issues that have been challenges for thermosetting prepregs, such as low-temperature transportation, freezing storage, and property degradation due to thawing and refreezing. 【Features】 - A unique design with excellent gas permeability in the thickness direction reduces the occurrence of surface pinholes and internal voids. - Room temperature storage is possible due to a unique resin formulation technology. - It is a high-heat-resistant modified epoxy grade. These features enable a reduction in labor and costs throughout the entire process of transportation, storage, curing, and painting. *For more details, please refer to the PDF document or feel free to contact us.
