A material exploration into the properties of natural fiber composites (NFCs), sponsored by BASF Chemical. A mat of natural fibers (Kinaf) shot through with ABS threads is heated and then press-formed, resulting in a composite part. The thermoplastic melts and becomes a matrix strengthened by the fibers.
Brace use testing; pads by Aircast
NFCs are lightweight, and and simple to form. While lighter than most commercial plastics, NFCs are less resistant to compression and flexing. They are typically used for complex organic, but non-structural forms, such as car door interiors.
Because ankle braces are supports, but not entirely structural in and of themselves, they benefit from NFCs’ particular strength properties. The brace restricts lateral ankle rotation, and the slight flexibility of the NFC enhances comfort over long-term use. The brace is compatible with existing AirCast brace padding systems, and the foam/air pads can be easily changed if necessary. I have tested this brace on my own sprained ankle: it is easily as effective as standard hard-plastic braces.

Molded contours add rigidity while accomadating the ankle bones to minimze rubbing
Brace is made to be compatible with Aircast padding; as is customary, one size fits most once straps are adjusted.
