Abstract
An ankle-foot orthosis forming a monolithic structure and include at least two different material components. The first material component has at least one tape layer consisting of a continuous fiber-reinforced thermoplastic composite, and a second polymeric material component surrounds at least in part the tape and includes a thermoplastic material into which the first material component is embedded. A resin material of the first material component is bonded to the second polymeric material component.
Claims17
An ankle-foot orthosis, comprising:
- a monolithic structure comprising at least two different material components, wherein a first material component includes at least one tape layer formed by a continuous fiber-reinforced thermoplastic composite (CFRTP), and a second polymeric material component surrounding at least in part the tape and including a thermoplastic material into which the first material component is embedded;
- wherein a resin material of the first material component is bonded to the second polymeric material component;
- wherein the first material component comprises at least first and second tape segments spaced apart and secured to one another by the second polymeric material component wherein a peripheral edge of the first tape segment is surrounded by the second polymeric material component and wherein a periphery of the ankle-foot orthosis generally corresponds in shape to at least part of the peripheral edge of the first tape segment.
An ankle-foot orthosis, comprising:
- a monolithic structure having at least one layer of a continuous fiber-reinforced thermoplastic composite including a plurality of reinforcement fibers in a thermoplastic base resin, and a thermoplastic material component encasing the at least one layer of a continuous fiber-reinforced thermoplastic composite,
- the ankle-foot orthosis including a footplate having a line of progression extending from a heel portion to an ankle portion to a toe portion of the footplate;
- and
- a resilient leg support having first and second end portions with a middle spiral portion therebetween, the first end portion being inseparably connected to the footplate;
- wherein the leg support and the footplate are integrated by the thermoplastic base resin;
- wherein the at least one layer of continuous fiber-reinforced thermoplastic comprises first and second tape segments spaced apart a distance by the thermoplastic material component wherein the first and second tape segments having first and second interlocking sections defined by complementary shapes, for example, the first interlocking section has a protruding shape and the second interlocking section defines a recess adapted in shape to the protruding shape of the first interlocking section with a distance therebetween formed by the thermoplastic material component.
