Surface preparation has long been recognized as an important step in creating a solid bond and is the key to maximizing strength and durability. The ability to produce well-bonded parts can eliminate the need for expensive fastening processes that add weight and stress to a component. However, while long-standing processes such as manual processes and dry blasting are traditionally used, the ability to deliver precise and reproducible results is limited. This may result in established processes not meeting the required certification levels for composite parts.
Wet blasting process combines compressed air, blasting abrasive and water in the form of a slurry, creating a mechanical process that provides an abrasive effect. Wet blasting as an alternative mechanical process can provide manufacturers with better precision and repeatability when preparing composite parts. Addition of water creates a lubricating effect allowing the slurry to flow off the surface. Compared to other methods, the fluidity of abrasive in wet blasting makes processing complex shapes much easier, while also providing homogeneous surface finishing for more consistent bonds between parts to be joined.
Manufacturers must constantly seek different and often new ways to achieve better inter-part bonding as the demand for composite parts increases. Manufacturers looking to improve the surface preparation process can meet new challenges and find new ways of using composite materials.
When it comes to high-value composite parts, reproducibility becomes even more important. Concerns about dry and manual etching suggest that perhaps just a few seconds of over sandblasting will damage the substrate and damage the part. Wet blasting can be used to prevent material tissue damage In such cases. The controllability of the air pressure as well as the slurry provides a well-adjusted blasting, giving no damage to the material substrate, even in the most difficult working environments. Formula 1 teams, aerospace and automotive manufacturers have incorporated this method into their production processes after realizing some advantages of wet blasting.
Wet blasting gives a very consistent and matte surface that increases surface roughness in preparation for bonding. It also enables the removal of resinous layers caused by protective resin treatments. Being able to control the grit concentration and the various flows means that blasting operations can be tailored to achieve a range of roughness grades. After the bonding process has been done, tensile tests can be used to test the adhesive strength. Since surface preparation plays an important role in improving adhesion, the test can also be used to distinguish between different preparation processes. When the existing surface preparation processes are evaluated; Wet sandblasting has scored very well with the surface quality it provides before bonding the parts and the strong bond formed afterwards. Thanks to wet sandblasting, the surface of the base material is processed homogeneously, which makes the bond life between the parts much longer.
As manufacturers want to work with increasingly complex composite materials and shapes, the need for surface preparation control increases. This has led leading sandblasting machine manufacturers to develop innovative solutions for greater flexibility and improved process control. In the case of highly demanding composites, the ability to remove any contaminants from the sandblasting process will be critical to ensuring a successful blasting process. Sandblasting, without proper filtration, can cause pollutants to be sprayed back onto the surface of the composite and subsequently disrupt the bond.
