CNF Nanocomposite Materials
(under development)
Light-weight and eco-friendly nanocomposite material
Our unique nanocomposite materials are composites of highly heat-resistant cellulose nanofiber (CNF) and various polyamide resins. The materials excel in rigidity, dimensional stability, as well as sliding properties, and are expected to be applied to various sliding parts. They also contribute to reducing the environmental impact of parts since they utilize biomaterials, have high mechanical recyclability, and reduce the weight of parts.
CNF nanocomposite material composited with various polyamides has excellent rigidity, dimensional stability, and sliding property. It contributes to downsizing, thinning, and weight reduction of sliding parts in all parts of automobiles.

High heat resistance and mechanical recyclability
During mechanical recycling, our highly heat-resistant CNF does not easily deteriorate by heat but lead to less fiber shredding. Therefore, even when injection molded parts made of the CNF are repeatedly shattered and remolded, there is low degradation of physical properties of resin composites. The CNF is highly heat-resistant, enabling itself to be combined with various polyamides such as PA6 and PA66.
High rigidity and dimensional stability
Polyamide CNF nanocomposite materials, which are based on our original CNF dispersion technology, have high rigidity. In addition, our CNF materials enable high modulus and low thermal expansion from low to high temperature.
Sliding characteristics
The CNF nanocomposite materials which are composites of CNF and polyamide achieve low friction coefficients, low wear, as well as low deflection, and have a feature that they do not easily wear objects which can be abraded (metals, etc.).
Reducing the environmental impact
The use of CNF, which is a bio-based filler and has excellent mechanical recyclability, as a reinforcing material for polyamide can contribute to reducing the environmental impact of materials. Our PA610-based composite material, 10% of which is composed of CNF, can achieve a bio-raw material ratio of 65%, contributing to further reduction of waste and CO2 emission.
Downsizing and light-weighting sliding parts
A nanocomposite of polyamide resin and CNF achieves rigidity which is far higher than that of non-reinforced polyamide, contributing to the downsizing, thinning, and weight reduction of sliding parts. Compared with glass fiber reinforced materials, CNF nanocomposite materials may enable the omission of special surface treatment processes for metals because the materials do not abrade the metals on which sliding occurs.
