High-Resistance Composite Laminated Shims
X.FIBER® is a unique laminated composite material developped by LAMÉCO which comes in the form of woven fiber sheets, which can be manufactured in several different ways: glass, carbon, aramide, ceramic fibers or any combination of two or more of these different fibers. The sheets are held together by a heat-hardened resin, the resulting material delivers both very high technical performance and excellent peelability.

Benefits of X.FIBER® laminated shims
Lightness
When the demand is for lighter materials, X.FIBER® proves itself by far one of the lightest of laminated materials (up to 8 times lighter than steel or brass!).
| Material | Specific Weight | Weight-saving | |
|---|---|---|---|
| X.FIBER-Glass® | X.FIBER-Carbon® | ||
| X.FIBER-Carbon® | 1.05 | - | - |
| X.FIBER-Glass® | 1.35 | - | 1.29 x |
| Stainless Steel | 8.2 | 6.07 x | 7.81 x |
| brass | 8.5 | 6.3 x | 8.1 x |
Strength
Being both lighter and stronger it can be used to great advantage as a replacement for carbon and stainless steels.
Endurance
It is comparable with laminated metals. X.FIBER® mechanical properties remain unaffected by the rise in temperature.Thus this product can be exposed without damage to heat exceeding 1,472°F/800°). Note that the limit of 572°F/300°C ofr the resin is not restrictive: beyond this limit the binder will be destroyed but the shim is still of the highest quality.
Anti-fretting
X.FIBER® is a total barrier against the galvanic coupling caused by surface contact of different metallic alloys. No further surface treatment is required.
Rapidity
The sheets (layers) can be peeled by hand, without the need for tools of any kind.
Safety
X.FIBER® is easily peeled without risk of finger cuts.
Ingenuity and Economy
Once they have been peeled, the sheets (layers) remain flat and free of deformation. They remain fully re-useable.
Physical & Mechanical Characteristics of X.FIBER® laminated shims
| Carbon Fabric: X.FIBER-Carbon® | PLUS glass fabric: X.FIBER-Glass® | |
|---|---|---|
| Density | 1.05 | 1.35, 1.37 or 1.39 (depending on thickness) |
| Comprensive Fracture Strength Limits | 1 570 MPa | 1 900 MPa (1) |
| Resin Temperature Resistance (2) | 300°C / 572°F | 370°C / 698°F |
(1) Physical limit of the test machine = no fracture.
(2) The Shim use is not affected by the possible disappearance of the resin, under the heat action.
