[vc_row][vc_column][vc_custom_heading text=”Crossfire<\/strong> developed some high valuable technologies to Circular Recycle the EoL<\/strong> based on Crosspreg\u00ae materials and technology<\/strong>. They are based on some few simple key concepts: <\/p>\n

The Recycling technology<\/strong> must be simple, cheap and environmental friendly.
\nThe cost for recycling<\/strong> must not exceed the Value of the recycled outputs<\/strong>.
\nThe Recycling technology must be tuned and selected according to the articles composition, to facilitate and obtain the highest Secondary Raw Materials Value<\/strong>. <\/p>\n

Those Technologies are: <\/p>\n

Mechanical Grinding\/Compounding<\/strong>
\nIt’s ideal, simple and very low cost, when the user have internal possibility to utilize the Secondary Raw Materials<\/strong>, and when the Composite part is made of Crosspreg\u00ae Glass Fabric<\/strong> based. Small\/medium size EoL articles, production cutoffs, scraps can be grinded in a mechanical grinder to obtain a short\/medium length chopped glass particles<\/strong> perfectly wet by Crosspreg\u00ae resin. The average content will be about 70% of glass and 30% of resin<\/strong>. The grinded powder will be added of some virgin resin (polyester or PP) and compounded into a twin extruder<\/strong> to sort out the pellets for Injection Moulding<\/strong>. Crossfire would work with the Partner to develop the ideal grinding\/compounding parameters to its highest final Value. It will be used for Injection Molding and over-molding<\/strong> with or without composite inserts. <\/p>\n

Pyrolysis<\/strong>
\nThe thermal degradation<\/strong> of the organic Epoxy matrix can give back a Valuable Carbon fabric<\/strong> to a new usage. An industrial Pyrolysis plant is already active in our geographic area, and capable to treat and recover carbon fiber EoL parts and scraps<\/strong>. Given the cost of the Thermal treatment, it\u2019s not worth to be used with Glass fabric whose Value is sensibly lower than that cost, even if technically feasible. The carbon fabric from Pyrolysis<\/strong> is without sizing and this creates problems to its re-use, but, Crosspreg\u00ae resin system<\/strong> is equally capable to impregnate it perfectly and create new articles. To be pointed out that parallel test on the Virgin and the Recycled Carbon fabric<\/strong> grade impregnated with Crosspreg\u00ae resin, shown very similar performances apart of a larger standard deviation due to the lost perfect fibers alignment. <\/p>\n

Solvolysis<\/strong>
\nThe Chemical degradation of Crosspreg\u00ae resin<\/strong> is feasible, cheap and quick, with any fabric and sandwich content. The process happens in MEG with a dedicated catalyst<\/strong>, at about 200\u00b0C, in minutes, and is without unsafe components. The output is represented by the organic molecular chain drop down to monomers in MEG solution<\/strong>, and the reinforcement (any) over other insoluble components (metal; microchips; incompatible plastics; ..) who separates by filtering the solution. The various Polyester and Epoxy monomers<\/strong> are separated by cooling crystallization, and all the various components are re-usable in a new formulation\/composition. The overall value of the recycled materials<\/strong> is a lot higher than the cost to obtain them. <\/p>\n

Repair-Reuse<\/strong>
\nBefore of wasting a Crosspreg\u00ae based article<\/strong>, a couple of developed technologies could help our Partners. <\/p>\n

Repairing<\/strong> is easy and quick just by cleaning the damaged surface and put a Crosspreg\u00ae patch<\/strong> over, than keep a bit of pressure while heating and curing. The cured Crosspreg\u00ae remains its Ionic activity<\/strong> capable to bond a new uncured patch and consolidates together. <\/p>\n

Reuse<\/strong>, with the limits of a material who doesn\u2019t stretch because of the fabric, is a possibility for simple shapes. The cured Crosspreg\u00ae<\/strong>, while heated at 180-200\u00b0C<\/strong>, is thermoformable<\/strong> in a cold mould in a few seconds.
