From TFP to HV-TFP
TFP stands for “Tailored Fibre Placement”. It is a textile manufacturing technology which lays down on a flat support (“base material” bellow) a fibrous material (“roving” bellow) held in place by stitches. Orientations of fibres are totally free (curvilinear paterns) allowing to produce “net shape preforms” with virtually no material scrap and optimised mechanical performances. An example is shown bellow for a “truss-like” part.
This technology allows a great variety of design and functions integration (heating element, electronic devices, sensors, RFID chip and antenna, …), but suffers from a rather low productivity.
To overcome this limitation, NOBRAK has developped a “patents pending” new version of TFP called HV-TFP for “High-Volume TFP”
| COST REDUCTION | FUNCTION INTEGRATION |
| No material scrap, reduced laying time for operators, increased repeatability | RFID chips, heating elements, electronic devices with com/power wires, metallic inserts, … |
| REDUCED ENVIRONMENTAL FOOTPRINT | Z-REINFORCEMENT |
| Thermoplastic composite, no scrap, natural fibers, reduced overall energy consumption | Through-thickness sewing for both monolithic and sandwich preforms. Kevlar, polyester, glass … sewing material |
