There are various methods for molding composite materials, but generally, it is done through external pressure molding. The irregular cross-section tubes can be molded using our unique internal pressure molding method, allowing for the formation of CFRP tubes with various cross-sectional shapes, such as polygons, as shown in the photo. FRP can be considered the only material that allows for the design of variable thickness structures among structural materials. Therefore, it is necessary to integrate the structure as much as possible, avoid secondary bonding, and ensure a compact structural design. *For more details, please download the PDF or contact us.*

●Optical Equipment Housing Utilizing the low thermal expansion properties, which is one of the characteristics of CFRP, we will manufacture housings and structural products with minimal dimensional changes at varying temperatures. 【Overview】 The relationship between the lenses and the tube of a telescope is similar to the structure of the human eye. The lens of the eye, known as the crystalline lens, can change its thickness through the ciliary body, allowing it to adjust the retinal image. In a telescope, the tube can be considered analogous to the retina. However, in telescopes, any displacement in the diameter of the tube can lead to critical defects. Carbon fibers have a negative linear expansion coefficient when considered individually, so it is expected that by orienting them appropriately, we can create structures with “±0” expansion, meaning that the expansion and contraction due to temperature changes will be minimal. ★For more details, please request materials or download the documents★

● Unlike conventional wind turbines, the uniquely shaped blades of this turbine rotate in opposite directions, which reduces efficiency loss due to convection and allows for power generation even in light winds. Additionally, it is constructed from materials with good radio wave permeability, making it less likely to cause radio interference even in environments where various frequency bands are present. ● Wind power generation is the most economically viable and efficient among renewable energy sources, showing a global growth rate of over 20% annually. To improve power generation efficiency, wind turbines have been made larger, but in recent years, there has been a shift towards pursuing efficiency by changing the shape of the blades. Our GFRP structure is used in the wings of this generator.

● A product that applies the structural theory of radar domes (Radar Dome) that does not degrade the performance of radio waves emitted from the radar. Speakers also require a structure that transmits a certain frequency band without loss, just like radio waves. Care must be taken in the selection of hardeners that increase “tanδ” in matrix resins, as well as in preventing the contamination of impurities. ● As the frequency increases, the wavelength shortens, necessitating a thinner cover; however, this simply reduces mechanical strength. Therefore, materials with high specific rigidity and specific strength are advantageous. Additionally, since the transmittance changes depending on the angle of the incident radio waves, a larger diameter is preferable for spherical radar domes. ★ For more details, please request materials or download the documents.

● We accept processing into various shapes according to customer specifications. Although it may not be apparent from the exterior, the interior can have a lattice structure or foam structure, and it is also possible to embed vacuum piping. When compared to aluminum of the same dimensions, improvements of approximately 50% in both amplitude and damping time can be expected. ● Many robotic forks adopt a scalar method, but when transitioning from one command to the next, vibrations must converge. This series of movements constitutes the takt time and serves as an indicator of production efficiency. Carbon fiber has a very high natural frequency, making it a suitable material for these applications. ★ For more details, please request materials or download the documents ★

● X-ray Transparent Medical Bed An X-ray transparent medical bed utilizing one of the features of CFRP, which is its X-ray permeability and high rigidity. It employs a sandwich structure with a foam core material. Compared to conventional structures, it is lightweight and achieves a laminated structure with excellent bending rigidity. 【Overview】 X-rays are more easily transmitted through materials with lower atomic numbers. Since CFRP is composed of elements such as "H" (atomic number: 1), "C" (6), "N" (7), and "O" (8), it can be said to have a much higher transmission rate compared to aluminum alloys and GFRP. The transmission rate of CFRP is about five times that of aluminum alloys. ★ For more details, please request materials or download the documents.

Sandwich panels are composed of skin materials and core materials, which are integrated through heating and pressurization using methods such as hot press molding or autoclave molding. Sandwich structures can be broadly classified into honeycomb sandwich structures and foam sandwich structures, depending on the type of core material. Our company is capable of manufacturing either type. Recently, applications in furniture and interior products have also been developed. By using a sandwich structure, when bending rigidity is kept the same, the weight can be reduced to 12-15% of aluminum panels and 20-25% of CFRP (PAN-based cross) panels. ★ For more details, please request materials or download the documents ★
