Moreover, closed-form expressions for the bolt load transfer rates and maximal adhesive stresses of balanced single-lap HBB joint with two identical fasteners are derived. It is shown that the FGAs allow fort a better load sharing between the adhesive and the fasteners than the HA.
Moreover, the use of FGAs instead of HA could lead to a potential static strength benefit for the adhesive layer part rather than for the fastening part. Google Scholar. Crossref Google Scholar.

Visual of Henkel hybrid adhesive line Newly introduced hybrid adhesives represent a patented technological breakthrough. Hybrid adhesive technology Henkel Corporation has developed a portfolio of patented technology structural hybrid adhesives that combine benefits and advantages of multiple adhesive chemistries into two-component hybrid adhesives. Traditional epoxy technology Epoxies are two-part structural adhesives that cure at room temperature or a one-part product that cures at elevated temperatures. Traditional acrylic technology Acrylics are traditionally two-component adhesives that can be either two-part or two-step.
Structural assembly Structural and hybrid adhesives can be utilized in a variety of applications, but the requirements of each application dictate which adhesive would be most applicable for that scenario. Figure 2.

Analysis Structural adhesive considerations Though epoxies and acrylics are excellent choices for many structural applications, they still have their disadvantages. Mainly, they have long fixture times that tend to be much slower than other chemistries.
Typical fixture times for epoxies range from 15 minutes to two hours,2 which can be problematic for many applications requiring high throughput and low work-in-progress WIP. Polyolefin plastics are the most common type of hard-to-bond plastics because of their low surface energy. Though these adhesives maintain fast fixture time, i.

Results and discussion Hybrid adhesives in the structural market Hybrid adhesives provide a patented technology solution to many unmet needs of the structural market through the following value drivers. Rising demand for weight reduction: Hybrid adhesives can be used as a universal bonding agent, allowing lighter substrates to be used and removing the need for mechanical fasteners.
Rising demand for reduced manufacturing time and cost: Hybrid adhesives offer faster cure than traditional structural epoxies. Faster cure products result in faster production cycles, less down time, less storage space, etc. Increasing penetration of composites and other new enabling substrates: Excellent adhesion capabilities of hybrid adhesives and formulation flexibility can lead to new design options.
Increasing demand for high-performance structural adhesives: Hybrid adhesives can help to improve overall performance due to well-balanced properties, even with impact resistance slightly lower than other structural bonding adhesives.
Increasing demand for low hazardous and sustainable structural adhesives: Hybrid adhesives offer many benefits over traditional structural technologies when comparing environmental health and safety hazards. Rising demand from emerging markets: Hybrid adhesives have been launched globally within Henkel Adhesive Technologies and will be made available for sale in 50 countries. Many customers prefer the option of one product for multiple applications. Customers now may find it easier to serve multiple applications with a hybrid adhesive than with traditional structural adhesive products.
Conclusions Modern designers utilize various substrates to achieve products that physically could not be produced in the past. Burns, Rory B. Barnes, Ray P. Tully, and John Guthrie. Henkel Ireland Limited, assignee. Patent US A1.
