This section is intended for engineers who wish to check the impact of adding a FireShield® layer to a composite laminate.
Not all potential issues have been researched. If there are critical parameters in the design, prototype laminates should be prepared and tested. Regina offers a free service to review prototype samples prior to fire testing. If you forward one of your test samples prior to submission to the testing authority, we can offer an opinion based on successful prototypes that we have examined.
Please forward any prototype test sample to the factory with a covering note, and we will aim to respond within a maximum of one week. For Technical Data Sheets, click here.
Fire performance below 800°C
Theoretical calculations can provide indicative design information, but prototype testing is needed to confirm fire performance.
Expect Char thermal conductivity = 0.04-0.07 J/m.K.
Multi Layer Panels
(Passive Fire Protection Panels)
The data in the following table can be used to determine theoretical minimum cost/weight/thickness, using the predictive equations provided in the pdf below.
Fire performance above 800°C
Above 800°C the relevant properties of a surface layer include self extinguishment and integrity retention.
Where FireShield® is replacing an existing surface tissue, bulking of the material in die or mould is unlikely to be a concern.
Potential maximum compression of the substrates, without FireShield® chemical, is:
Glass Cloth - plain or satin
As the outer plies are not usually considered to contribute to the physical properties of a laminate, no impact is expected on designed strength, stiffness or TG from the use of a FireShield® layer.
Surface hardness should be tested, to ensure that significant chemical “wash” into the resin that moves through the FireShield® to the face, has not occurred during manufacture.
FireShield® can be converted into a pre-preg form in the usual way.
Using FireShield® as a pre-preg has the advantages that it eliminates chemical shedding, and provides a material with tack, convenient for vertical lay-ups.
Regina can arrange for pre-preg manufacture, with the resin nominated by the client. Shelf life can be preserved by transporting the rolls in dry-ice packs, or by using refrigerated containers.
