Rubber bellows optimally reinforced

Ideal fibre path

Ideal fibre path on bellow shape
In a fibre reinforced product it is essential that the fibres follow the direction in which the forces must be guided. Corpo reinforcement uses the ideal orientation which improves product performance. In the figure such an ideal path is drawn at which fibres are used at 100% of their strength. Under these conditions the fibre structure provides all the strength the product needs. Hence the rubber does not have to take up sheer stresses. Corpo uses materials the way they are meant to be used which leads to a higher product performance using less material.

• Each rubber bellow only has one optimal fibre path
• On the optimal path the fibre uses 100% of its strength

Conventional rubber bellow reinforcement

Rubber bellow with fabric ply reinforcement
With conventional reinforcement methods for convoluted shaped products, such as wrapping or knitting, it is not possible to apply the fibres on their optimal paths. Often the difficulty to influence the fibre orientation means that the fibre path deviates many angular degrees from the ideal path. Only 5° deviation from the ideal path already leads to 50 % loss of strength of your product. Another problem is that this makes it impossible to predict and control the shape of the product under pressure.

• Conventional methods can not place fibre on optimal path
• Only 5° deviation from the ideal path leads to 50 % loss of strength

Corpo™: optimal reinforcement for rubber bellows

Corpo reinforced bellow shapes
TANIQ’s patented Corpo™ reinforcement technology defines the optimal shape of the convolute and the ideal path of the fibres. With this you can control the shape and have the product benefit from 100% of the strength of the materials. Existing highly automated production techniques can be used for the Corpo fibre placement. The benefits are: A reduction of material and labour costs and an increased product performance in terms of flexibility, pressure resistance, weight and control over geometry.

• Corpo™ reinforcement provides optimal reinforcement structure
• Increased performance in terms of flexibility and pressure resistance
• Reduction of material and labour cost
