Adhesive failure is characterized by a failure of the joint at the adhesive–adherend interface and is typically caused by inadequate chemical and/or mechanical preparation of the surface.

2021年9月14日 · The failure can happen between the adhesive and either of the two substrates, it is bonding together. Cohesive failure happens in the adhesive itself or inside the layer of a coating.

Adhesive bonds can sometimes fail. But there are different types of bond failure. Read this article to understand why your bond failed.

2018年6月26日 · Adhesive failure occurs when the adhesive system debonds or separates prematurely from one of the surfaces or substrates. In some cases, you want adhesive failure; particularly if you want the tape to peel cleanly away from the substrate (think of a Post-It Note). In most cases, however, the reality is a bit more complicated.

The paper discusses the impact of adhesion and mixed-mode failures on the regulatory framework for certification and continuing airworthiness management of adhesive bonded aircraft structure. It outlines the difficulties in quantifying mixed-mode failures and how a lack of understanding of this failure mode has led to erroneous findings.

2024年7月22日 · Adhesive failure occurs when the adhesive bond between the substrate (the surface to which the adhesive is applied) and the adhesive itself fails. In other words, the failure happens at the interface between the adhesive and the substrate.

Adhesive failure is an interfacial bond failure between the adhesive (coatings, printing inks, sealants) and adherend. The failure mode refers to the mechanism by which an adhesive bond breaks or fails due to as a result of applied stress or force.

2019年3月28日 · Adhesive failure is a common issue when using too much adhesive. Following are some examples, probable causes, and suggested solutions. Note: Problem – Slow cure time. Cause – Low moisture to adhesive ratio. Cyanoacrylates bond when trace amounts of moisture deactivate the adhesive’s built in stabilizer.

2015年10月15日 · Adhesion failure, otherwise known as de-bonding or failure, is one of the most common types of failure mechanisms. This failure mode occurs when the adhesive does not tear or split, but instead pulls away from one or both substrates.

Adhesive failure happens when a load surpasses adhesion, causing failure at the adhesive-substrate interface. It can be resolved by modifying surface prep or adhesive choice.
