Abstract
Techniques are provided for producing low-cost FRP composites which contain heavy tow fibres. Techniques are provided for uniform impregnation and efficient bonding of these heavy tow fibres which eliminates “racetracking,” thus resulting in cost-effective and well performing FRP composites.
Claims29
A method of manufacturing fibre reinforced plastics (FRP) composites, comprising:
- impregnation of heavy tow fibres with a low viscosity resin.
A method of manufacturing fibre reinforced plastics (FRP) composites, comprising:
- impregnation of fibres with resin from an injection side towards a downstream side, wherein a pressure on the injection side is incremented stepwise.
An apparatus for manufacturing FRP composites, comprising:
- a reduced cavity high at edges of a mould wherein fibres or fibre fabric is placed;
- a clamping mechanism to prevent displacement of the fibres or the fibre fabric;
- and
- a pressure ramp injection system, wherein a resin is injected into the mould under stepwise increments of pressure.
