16) Place two layers of carbon fibre cloth (e.g. 15 cm x 15 cm) offset over
the lamination anchor arms.
17) Pull one layer of Perlon stockinette over the model.
18) Pull two layers of carbon fibre stockinette over the model.
19) Pull two layers of Perlon stockinette over the model and tie off below the
cap screw of the lamination anchor.
20) Pull a soaked PVA bag over the model.
21) Perform the casting process with Orthocryl.
22) After the lamination resin has cured, remove the lamination dummy.
5.3 Laminating a Transtibial Socket
Required tools and materials:
>
711S4* bending iron, 99B81 PVA bag, 623T3 Perlon stockinette, 616B1
carbon fibre cloth strap, 699B1 fibreglass roving, 616G12 carbon fibre
cloth, 616G15 carbon fibre stockinette, 617H119 Orthocryl lamination
resin 80:20 PRO
1) Mount a screwed insert according to chapter "Mounting of the screwed
insert" (see Page 16).
2) Pull a soaked PVA bag over the model. The PVA bag should be sealed
by heat welding at the distal end.
3) Pull two layers of Perlon stockinette over the model.
4) Place three layers of carbon fibre cloth (e.g. 15 cm x 15 cm), offset on
the distal end of the model.
5) Pull two layers of Perlon stockinette over the model.
6) Bring the lamination anchor arms in the correct a - p and m - l position.
Never align the threaded clamping in the anterior or posterior direction.
7) Place the lamination anchor at the socket end as required for proper
alignment and set.
8) Optional: Adapt the anchor arms of the lamination anchor to the model
with a bending iron.
9) Apply the lamination dummy according to the instructions in the chapter
headed "Installing the lamination dummy" (Installing the Lamination
Dummy).
10) Stabilise and fix the lamination anchor with a sealing resin/talcum
powder mixture.
11) Pull the fibreglass roving through the holes in the anchor arms and allow
it to hang in a loop. If there are no holes, allow the fibreglass roving to
hang around the anchor arms in a loop.
12) Place three layers of carbon fibre cloth (e.g. 15 cm x 15 cm) offset over
the lamination anchor arms.
