Foot Orthosis

At the request of a polio survivor, a partially flexible thigh cuff made of leather and canvas for a carbon KAFO was devised to allow the wearer to feel more comfortable while sitting on a toilet seat. The original, acrylic resin, thigh cuff was partially excised to make an opening (15×10 cm), which was stuffed with rubber sponge, and was sealed with leather and canvas. The opening's surround was vertically and horizontally reinforced with carbon fibres. This modification provided relief to the polio survivor from the discomfort previously experienced while sitting on a toilet seat, and satisfied her needs in daily life.

Abstract A laser-assisted 3D printing process of carbon fibre reinforced plastic parts with sandwiching fibres between plastic layers was developed to improve the bond strength of the fibres to the plastic layers. In this process, the bunded carbon fibres were placed on the 3D-printed lower layer, then the upper plastic layer was deposited on the fibres, and the two layers with sandwiching the fibres were laser-heated. The heating temperature at the interface between the fibres and the plastic layer was changed by the colour of the plastic layer because of the transmittance and absorption of laser beam, and the translucent layer was most appropriate. Not only the strength but also the rigidity of the 3D-printed carbon fibre reinforced plastic part was improved by laser heating. Carbon fibre reinforced plastic parts having closed cross-section was manufactured, and strengthened by optimisation sandwiched fibre orientation. A tailored part locally reinforced by carbon fibres was 3D-printed.

Carbon Fibre Reinforced Plastic

AbstractVoids and cracks can fatally degrade structural materials such as metals and ceramics but are tolerated in carbon fibre-reinforced plastic (CFRP) composites if monitored to prevent their growth to a critical size. Thus, the use of CFRPs as aeronautical structural materials requires an understanding of microscopic crack formation. However, this crack-formation mechanism remains unclear because experimental difficulties have hindered studies of relevant phenomena that occur before crack formation. Herein, we report high-resolution (~50 nm) and non-destructive three-dimensional observations of crack initiation and propagation under applied stress. This evaluation reveals that voids and cracks do not simply result from local stresses but instead occur largely through two competing nanoscale mechanisms, namely, fibre/plastic interface debonding and in-plastic crack initiation. Therefore, nanoscopic insights into these heterogeneities are essential for controlling crack initiation and determining reasonable safety margins for CFRP composite use.
