サカイオーベックス List of Products and Services

Sakai Oubex is developing "prepreg" using carbon fiber open filament and carbon fiber open filament woven fabric. It can be provided in various intermediate shapes according to the application. It is also possible to change the type of resin used for impregnation, such as thermosetting resins or thermoplastic resins. This is an intermediate substrate for the manufacture of CFRP (carbon fiber reinforced plastic) and CFRTP (carbon fiber reinforced thermoplastic). [Features] - Can be provided in various intermediate shapes according to the application - Possible to change the type of resin used for impregnation, such as thermosetting resins or thermoplastic resins - Intermediate substrate for the manufacture of CFRP and CFRTP *For more details, please refer to the PDF document or feel free to contact us.

Sakai Oubex has established a manufacturing method for open fiber yarns that spread carbon fiber bundles into tape form, based on patented technology from Fukui Prefecture, as well as for textiles made using these open fiber yarns. Our carbon fiber products fall under the list of regulated goods in the middle column of Table 1 of the Export Trade Control Order. Additionally, products made using these materials as raw materials may also fall under the list of regulated goods. [Features] - Our open fiber yarns and open fiber yarn textiles are thinner compared to conventional products. - Due to their thinness, when made into textiles, they have fewer surface irregularities and less reduction in strength. - Both open fiber yarns and open fiber yarn textiles are thin, making resin impregnation easy. *For more details, please refer to the PDF materials or feel free to contact us.

The "open fiber woven fabric" made from carbon fiber open yarns is characterized by being thin, lightweight, having minimal irregularities, a small weaving angle, excellent resin impregnation properties, and difficulty in interlayer delamination, demonstrating superior fatigue characteristics with high physical property values. Laminated boards produced using "carbon fiber open yarn woven fabric" have resin and carbon fibers uniformly dispersed, resulting in improved mechanical strength. Additionally, laminated boards using "open fiber woven fabric" are less prone to transverse cracking and have reduced interlayer delamination, leading to enhanced fatigue strength. 【Advantages (Fiber Bundle)】 ■ Thin, lightweight, minimal irregularities, and small weaving angle ■ Excellent resin impregnation properties and difficulty in interlayer delamination ■ High physical property values indicating superior fatigue characteristics *For more details, please refer to the PDF document or feel free to contact us.

Sakai Ovex is promoting the development of carbon fibers as a new business in the non-apparel sector. Carbon fibers not only have the characteristics of being lightweight, strong, and corrosion-resistant, but they also excel in conductivity, heat resistance, dimensional stability, and chemical stability. Due to these excellent properties, they are used as advanced materials in various fields such as aerospace, construction, civil engineering, vehicles, and ships, and their applications are continuing to expand. [About Open Fiber] - The process of spreading carbon fiber bundles, which are used as reinforcement materials for carbon fiber composite materials, into a wide and thin state is called open fiber. - Based on patented technology from Fukui Prefecture, a manufacturing method for open fiber yarns that spreads carbon fiber bundles into tape form has been established. - Thousands to tens of thousands of carbon fibers are spread out in the width direction, and the cross-section is flat. *For more details, please refer to the PDF document or feel free to contact us.

"OVEX Fabric" is a carbon fiber intermediate molding material that is thinner and lighter than conventional textiles. By controlling the width of the open fibers, the fiber weight (FAW) can be designed as desired. We can provide fabrics using various types of carbon fibers, from standard types to high-elasticity types. Additionally, we offer resin-impregnated intermediate materials "prepreg" and "semi-prepreg" for molding. 【Features】 ■ Thinner and lighter than conventional textiles ■ Fiber weight (FAW) can be designed as desired ■ Fabrics can be provided using various types of carbon fibers *For more details, please refer to the PDF materials or feel free to contact us.

This document introduces the mechanical strength and internal damage suppression effects of CFRP and CFRTP with a thin-layer structure. It explains the improvement of mechanical properties due to the reduction of crimp angle associated with thinning, as well as the bending strength of woven CFRP laminate, using graphs and photographs. Please take a moment to read it. 【Contents】 ■ Improvement of mechanical properties due to the reduction of crimp angle associated with thinning ■ Internal damage suppression effects of thin-layer CFRP composite materials ■ Bending strength of woven CFRP laminate *For more details, please refer to the PDF document or feel free to contact us.
