Measurement of Joint Durability between an Aluminum Foil and Basalt Fabrics

The aim of this paper was to determine the adhesion force between an aluminum foil and basalt fabrics. Aluminised basalt fabric can be used as an alternative solution for protective clothing production. So far aluminised glass fabric has been used for this purpose. The lamination of basalt fabrics with aluminum foil does not changed fabric flexibility and can provide better protection against thermal radiation. To check different variants of adhesion, fabrics reinforced by a steel wire were also used (wire diameter 0.1 mm). The steel wire caused an increase in the fabric tear strength as well as in puncture and cut resistance. Two types of glue were chosen to carry out an investigation on the strength of adhesive bonding (Butacoll A+ and Bonatex PU85). The adhesion strength of the laminates was measured according to the PN-88/P-04950 standard. The test results confirmed higher values for weft directions and the phenomenon of asymmetry of the bond strength was found during testing.
