Frame and container preforms made of carbon

Efficient reinforcement for prosthetic sockets

Preforms represent a new generation in transfemoral socket fabrication.

Highly rigid frame and container sockets can be produced with little effort by using prefabricated carbon elements.

In this context, prefabricated means that:

Due to a special manufacturing process, the carbon fibres are oriented according to the load, corresponding to the forces that occur in the socket. High stiffness is guaranteed as a result. At the same time, the carbon fibres permit a low socket weight by minimising the use of material.
The carbon set consists of three separate pieces that can be applied directly to the isolated plaster model using spray adhesive (636K40). This application saves time as there is no need to cut carbon fibre mesh supplied in rolls or sheets, including double-sided tape.

Since the layer structure of the prefabricated pieces is pre-determined, mistakes during reinforcement that could for example affect the stability of the socket are avoided. Using preforms also reduces waste that is produced when reinforcement materials are cut to size.

All benefits at a glance

Clean and easy processing
Pre-determined layer structure
Simplified fabrication and less time to fabricate a socket
Waste of expensive reinforcement materials is minimised
Simplified quantity control in comparison to rolled and sheet goods

Processing instructions

Apply the M/L section with the short side oriented medially. Round the edges when shortening to the correct length.
Wrap around the radial section: position the reinforcement triangle medially in the perineum with the point towards the end of the residual limb. The radial section can be used for left-hand (carbon on the outside) and right-hand (carbon on the inside) sockets. Perform the first casting with the M/L section and the radial section.
Attach the anchor and position the faces of the star so they are centred over the anchor arms. Perform the second casting with the anchor and star.

The carbon preforms can be processed with all Ottobock resins.
