  The base of S-Beam is a laminated core with specific properties that makes metallic composites possible.

  Manufactured in continuous process, S-Beam Core is low density; uncompressible; heat curable and structurally bondable with metal sheets. It is also compatible with traditional automotive OEMs process, lay outs, adhesives, sealers and paint systems.
  
  Formulation can be adjusted to better perform according to different applications, combining metals or other substrates as fiberglass and carbon fiber.
  
  At Cipatex R&D, we are motivated to contribute for a better world, so we continuously search for innovations that can result in a more efficient and sustainable use of our products and technologies.

  S-Beam Concept

  S-Beam (Fig. 1) is a sandwich composed by a synthetic core (A) covered by metal skins (C) coupled with heat curable adhesive (B).
  
  During stamping operation (Fig. 2) S-Beam molds easy, as the metal sheets are thin and slides over the core by the still liquid adhesive. After exposure to E-coat bake oven (Fig. 3), S-Beam cures and acquires the condition of structural sandwich, transforming bending efforts into tensile/compressive forces developed over the extension of the surfaces. This concept increase stiffness significantly.
  Flexion test: Due to it uncompressible core, S-Beam maintains dimensional integrity until collapsing over force application area (fig 4).
  S-Beam allows 50% weight reduction with same resistance to flexion than a sole metal sheet, is self extinguishable, recyclable, has low thermal conductivity and absorbs sound and vibrations.

  S-Beam advantages

  STAMPING Easy to stamp and cut. Total metallic substrate represent less than half that if it were a single sheet.
  STAMPING/BODY SHOP Bondable with standard structural adhesives. Compatible with hem flanging operations, also accepts induction pre-cure.
  PRE-TREATMENT/E-COAT Compatible with spray and immersion processes. S-Beam core protects inner sides of metallic skins against corrosion.
  E-COAT BAKE OVEN S-Beam can be formulated for high or low cure E-coats. During bake cycle, S-Beam achieves high resistance.

  Cipatex S-Beam, a new technology of metal sheet for external panels, that reduces weight by 50%

  S-Beam is the latest technology developed by Cipatex to improve efficiency for a sustainable mobility.
  S-Beam (S- means Sheet) is an easy to stamp metallic sandwich,composed by a heat curable core(B) skinned with metal sheets (A).
  S-Beam provides same stiffness and resistance to flexion than standard metal sheet, with half a weight. Made in aluminum or steel, S-Beam is bondable, recyclable and fully compatible with same traditional OEMs process, materials and layouts.
