We select fibers and matrices according to the customer's purpose/application and provide prepreg! (Development product)
We developed prepreg by combining the powder technology cultivated in our abrasive manufacturing, the slurry technology for dispersing powders, and the sheet-making technology for creating homogeneous sheets. By sintering the prepreg, it becomes a Ceramic Matrix Composite (CMC). Since CMC is composed of ceramic components such as silicon carbide, it offers better heat resistance and is lighter than existing heat-resistant alloys. An example of CMC using our prepreg, SiC/SiC, demonstrates superior fatigue characteristics at high temperatures above 1200°C compared to existing metals and CMCs. 【Features】 - Expected reduction in production costs and simplification of processes compared to conventional CMCs. - Ability to prototype prepregs tailored to specific purposes/applications. - Support not only for prepregs but also for our powder technology, slurry technology, and sheet-making technology. 【Expected Applications】 - Aerospace sector: combustion chambers, turbine blades, shrouds, nozzles. - Energy sector: fusion reactors, cladding tubes, channel boxes. - Automotive sector: brake discs, friction materials, exhaust systems. - Machine tool sector: crucibles, setters, bearings, large tables.
