Average MD and CD residual tensile strength after 25 double folds under a pressure of 2 kg on 15-mm wide strips but under no tension, performed in a device similar to that described by Brecht and Wesp (21). 

ISO 4600 details a ball or pin impression method for determining the ESCR. In this procedure, a hole of specified diameter is drilled in the plastic. An oversized ball or pin is inserted into the hole, and the polymer is exposed to a stress cracking agent. The applied deformation, given by the diameter of the ball or pin, is constant. The test is multiaxial, relatively easy to perform, and with not very well-defined specimens, and the influence of the surface is limited. Drawbacks are the small testing surface and the undefined stress state. After exposure, tensile or flexural tests may be performed on the specimens. This leads to the determination of either the residual tensile strength or the residual deformation at break.

The results show quite good correlation of "acid" absorbance with residual tensile strength (fig 3). This type of relationship is potentially useful for examination of components in the field, since only a small sample is required and the structural integrity of the unit is not compromised. With appropriate care, curve resolving can be used to gain some insights into the hydrolysis process.

It is noted that the residual tensile strength depends primarily on the strength of the thermoplastic particles and the thickness of the thermoplastic layer within the narrowed crack. The reason is that the molten thermoplastic forms a thin film in the narrowed crack under the recovery pressure by the SMPFs, similar to the adhesive layer in an adhesively bonded joint (here the fractured two half beams serve as the adherends). It has been well demonstrated that the tensile and shear resistance of adhesively bonded joints highly depends on the adhesive thickness. A thinner adhesive layer usually leads to higher peel and shear resistance [28-32]. This is one reason why a 100% pre-strained SMPF leads to a higher healing efficiency because...

Structural products about 12 mm or more in thickness that are used for nonfatigue-critical structural applications will darken and have the surface stained as a result of weathering. Pitting corrosion will roughen the surface to a maximum depth of approximately 0.15 mm. However, the loss in residual tensile strength and load-carrying ability will be negligible.
