Sicomin launches new sandwich core concept at JEC World

Sicomin will launch new sandwich core concept at JEC World, next month. © SicominSicomin, a leading supplier of advanced epoxy systems “is redefining engineered sandwich construction” with the introduction of MaxCore, a new concept of sandwich core particularly suitable for infusion processes, which will be launched at JEC World, in Paris, next month.

Fibre reinforcements are inserted in multiple orientations and are responsible for 100% of the mechanical properties of the core, the company explains. With a unique patented manufacturing process, Sicomin is able to place these reinforcement fibres with precise fibre angles and positions within the core.

Due to the mechanical contribution of the fibre reinforcement, MaxCore doesn’t rely on denser and more expensive core material, so it is a cost-effective option, compared with classic foam cores used in composite panels. As the core material is solely a carrier for the fibre reinforcement, cores can be selected based on other required parameters such as: fire and smoke behaviour, water resistance, thermoformable ability, low resin absorption or sustainable chemistry.  

“The driving concept behind the MaxCore technology is maximising sandwich panel properties in large thickness formats.  The technology is particularly cost effective the thicker the core, for example from 30mm to 200mm or more,” said Comments Philippe Marcovich, President.

MaxCore’s patented fibre insertion method can be applied to kits in which fibre orientations are engineered within each panel to incorporate openings such as windows and doors, and to provide additional local reinforcement.

MaxCore is also compatible with a variety of manufacturing processes and can be used with epoxy, polyester and vinylester resin systems. Its fibre insertion technique can be applied with a variety of materials, including aramid, carbon, basalt, natural, thermoplastic and glass fibres.

“We are delighted to launch MaxCore at JEC World 2019. This new innovative core technology will revolutionise infusion processes and its associated costs. It will also open up new markets for us; Sicomin will also supply engineered cores in very large panel formats that deliver maximum performance using cost effective raw material options,” concluded Mr Marcovich.

Technology on display will include panels infused with Sicomin’s Epoxy infusion SR 8100 and Infugreen 810 with 4mm glass tows at 70% fibre content in weight; a 50mm fire retardant panel infused with Sicomin’s intumescent SR 1125 epoxy, with inserted 4mm glass tows providing a 63% fibre content in weight; and a flax fibre reinforced panel produced with Infugreen 810 (38% carbon content from bio-based sources), 50mm PET core, hybrid flax & E-glass skins and a bio-based Epoxy Gelcoat.
