SAERcore is our patented product range for closed injection processes such as RTM (Resin Transfer Moulding) and RTM light, together with infusion processes. The highlight: SAERcore delivers an optimised resin flow zone of polypropylene (PP). This causes the resin to flow four times faster – and even five times faster with our special high-flow variant.
SAERcore is a stitched (optionally glued) sandwich complex which, in its basic version, consists of one or two layers of chopped strand mat (CSM) and a core of PP (resin flow zone). Initially the resin flows horizontally into the core material and then impregnates the outer reinforcements through vertical injection. This “two-stage impregnation” process saves a significant amount of time, because the flow enhancer causes horizontal injection throughout the full width of the component to experience extreme acceleration.
The outer reinforcements can be freely adapted and comprise optionally of one or two layers of chopped strand mat. Here, the CSM fibres are again freely selectable. Our multiaxial technology is integrated into the SAERcore MAX product, which means that the sandwich complex is additionally reinforced with multiaxial interlaid complexes.
SAERcore and SAERcore MAX don’t only deliver time savings in terms of the resin flow speed – both product variants are available in combination with SAERfix, which means that the mould filling time can again be drastically reduced. To achieve an optimum surface appearance for the finished component, SAERcore can be supplemented with an additional non-woven covering. On request, SAERTEX can also produce customer-specific kits that again significantly accelerate further processing.
