A cleaner way to acheieve vacuum bagging perfection.
This process is essentially the same as for vacuum bagging
, except that you lay up the fabric dry and add a special resin at the end. The resin is drawn through the mould under vacuum and is absorbed by the dry fabric as it passes. Because, in theory, the fabric absorbes enough resin to fully wet it out but no more the finished part should always have the optimum resin content. It is also known as Resin Transfer Moulding (RTM).
