What is ISO 22841 about?
ISO 22841 specifies a method for determining the lap-shear strength of the adhesive joint between carbon fibre-reinforced plastics (CFRPs) and metal adherents, using a standard specimen loaded in tension and under specified conditions of preparation, conditioning and testing.
ISO 22841 is intended for assessing the suitability of adhesives to be used for bonding a carbon fibre reinforced plastic (CFRPs) to a metal.
Who is ISO 22841 for?
ISO 22841 on composites and reinforcements fibres is relevant to:
- Plastic industry
- Manufacturers and suppliers of epoxy adhesives
- Chemical engineers
- Product designers
Why should you use ISO 22841?
The lightweight design possibilities, changeable deformation behaviour, good corrosion resistance, and low electrical conductivity (depending on the fibre composition) are the key reasons for employing CFRP. In this regard, the tensile lap-shear strength test on adhesive joints, determines its ability to resist forces in the plane of the bonded surface between CFRP and metal.
With ISO 22841, adhesive lap-shear bond strength can be determined by stressing a single-overlap joint between a CFRP and a metal adherend in shear by the application of a tensile force parallel to the bond area along the major axis of the specimen.
Other information regarding the test procedure, reagents, test specimen specification and calculations are covered under ISO 22841.
As a result, ISO 22841 ensures that the quality of the structural adhesive as per the need of the application is optimal so as to enhance durability of a product. Moreover, it guides you in making the right choice of material that provides the highest strength under shear loading.
