・Various intermediate molding materials were developed by the opening technology for thinly spreading carbon fiber tows as a coretechnology.
・Fabrics using opened carbon fibers and materials molded by using UD have small crimps and high strength properties.
・We propose "OVEX fabric," which is an intermediate molding material with “thickness and weight” reduced to 1/2 or less of the conventional material and "OVEX prepreg," which is an intermediate molding material made by impregnating UD with thermoplastic resin.
Shortened cycle: 3 hours → severalminutes to tens of minutes
Weight reduction: (thickness 1/2 or less ofthe conventional material)
Higher strength/higher rigidity
・The 1 layer has the thickness of about 0.1 to 0.2 mm, and thus its degree of freedom in material design is low.
・Opened carbon fibers have the 1 layer with the thickness of 0.02 to 0.1 mm, and thus their degrees of freedom in material design are high and it is possible to introduce material design for further weight reduction.
・Thin-layer prepreg tapes using various resins (PA12, PA6, PC, PPS, and PEEK) can be provided.
