Summary: ● Utilizing additive manufacturing (AM) and multi-material approaches, achieving equivalent strength and rigidity while reducing the weight of aluminum machined products by 54%. ● Addition of cooling functionality and multifunctionalization leading to reduced temperature fluctuations. ■■ Reduced dimensional changes in bearing fitting dimensions → Suppression of vibration and extension of lifespan. ■ Expanded opportunities for cost reduction through the use of certified universal materials.
For future plans, you could consider the following:
● ● Further weight reduction through optimization of the honeycomb section according to AM manufacturing requirements. Evaluation of bonding between Aluminum AM and CFRP. We provide tailored proposals to meet your specific needs, including lightweighting and enhanced functionality.

Summary:
. By combining LEXTER fibers along with carbon fibers, separate resin injection is unnecessary. . . Various shapes can deform without reduction in strength and rigidity due to axial and radial elongation/shrinkage and changes in fiber crossing angles, eliminating the need for fiber fragmentation. The high deformability of the assembly alows for rough material arrangement in the mold, enabling the quick molding of complex-shaped pipes through pressurization and heating.
For future plans, you could consider the following:
. Torsion test, Compression test, Heat resistance test, Internal pressure test, Hydrogen leak test . . Integration molding with metal and rubber products Predictive analysis of mechanical properties after molding .
 Adhesion (bonding, fusion) evaluation .
 Coating evaluation . Inner surface polishing . Efficiency, Shortening, and Promotion of Mass Production in the Molding Process
For the application
. .
 Structural components (frames, shafts, irregular section pipes, T-shaped pipes, etc.) Piping (coolant, fuel, hydrogen, oil, insulation, double-layer, flexible, etc.)
