HIGH PREFORMANCE
 
Very high fibre fractions are achievable – in conjunction with high performance fabrics and resins this enables us to produce parts that exhibit performance comparable to pre preg items. In some instances VI parts can outperform similar pre preg parts because of the easier availability of tailored performance resins & fabrics.


 COST EFFECTIVE
 
  Low processing temps allow the use of cheaper tooling – this is particularly significant for short production runs where the cost of tooling is a major part of the cost of the finished item. High temp performance of finished parts can be achieved with post demould curing if required.


MATERIALS FLEXIBILITY
 
  Using dry fabrics gives us a huge and easily accessible choice of materials when designing layups. Similar applies with the liquid resins – a large range of resins with different specific properties are available off the shelf. o SURFACE FINISH Process delivers a microscopically thin unbroken resin film on the mould facing surface of the part giving a very high quality of finish – ideal for carbon car parts.
 

 MAINTAINING FINISH OVER A PRODUCTION RUN
 
  VI is very kind to moulds which allows us to maintain a much higher standard of finish over a moulds life o MOULD LIFE Mould life is greatly extended over traditional pre preg processes.


 PROCESSING HEAVY LAYUPS
 
  There is no top limit to the weight of a fibre pack that can be layed up and infused in a single shot – this is a strong advantage for large mouldings when compared to traditional pre pregs which need debulking after every few layers.


 PROCESSING CORED LAYUPS
 
  Cored layups can also be processed in a single shot. VI is a very simple process in principal – dry fabric is placed in a mould and bagged up – resin is then injected through the fabric driven by atmospheric pressure – when the resin is cured, the part is demoulded. In reality, designing a part for VI must include careful consideration of the process, as well as the part, inorder to achieve consistent quality and performance over a production run.
