“…Therefore, our findings, although conducted independently on a different testing apparatus, ASTM versus ISO, are fully in line with the work conducted by Massé et al [22] at the IRSST, Québec Canada. This is a good demonstration of the interchangeableness of the two equipments now both recommended in the ASTM norm.…”

High performance materials are rarely used as 100% compound, therefore most of the time when reference is made to these categories of materials it is as a matter of fact a reference to a system comprising a well-combined ingredients exhibiting together high performances in use. Fibres, micro-fibres and now nanofibres are definitely part of the high performance reinforcing ingredients, which in a system largely contributes to the performance in use of the designed system.High performance fibres, and more specifically aramids for their outstanding heat and mechanical properties, although most often used as reinforcing compound, are also used more uniquely and directly in situations where mechanical and thermal protections are required. It is therefore useful as a preliminary grounding to review these types of materials in terms of their properties. Then their attributes and potential contribution alone or in a system become more specific and can be extrapolated more easily. The mechanical performance and more specifically the cut resistance of articles made of high performance materials are generally measured against several norm specifications. Those are not designed to predict the "real" in use performance of the considered protective articles. This gap is even larger when the cut resistance of the compounding fibre increases. Although relationships exist between the various cut performance levels obtained with the ASTM, ISO and EN norms (respectively American, International and European standards), there is a need for a more fundamental understanding and interpretation of the data. The ASTM and ISO approaches remain the most suitable methods for that purpose. Various parameters, such as the high performance material and fibre composition, the effect of kinetic such as the cutting speed and the speed profile, the force distributions, the artefacts generated by various surface coatings are presented and discussed aiming at improving the interpretations of the data generated through the norm procedures. Therewith, significant progress in the understanding of the cut fundamentals and the norm harmonization are made available to the users of high performance fibres, such as KEVLAR®.

“…Several researchers have worked on introduced testers for the determination of the cutting resistance of fibers, yarns, and fabrics, which in each case can be applied for performing cutting of the material according to its end-use. [13][14][15][16][17][18][19][20][21][22] The emphasis has been placed on the recent developments in both test standards and experimental methodologies used to evaluate stab and slash protection.

In recent decades, attention has been focused on the design of protective soft fabrics against cutting. The anticipated textiles should shield the wearer's body from threats caused by pointed or sharp-edged objects, such as a knife, sharp blade, or spike. Therefore, as it is of great importance to design slash-resistant fabrics, it is also necessary to have an apparatus that gives the possibility to simulate the conditions of cutting processes of the protective fabric. The main objective of the present work is to develop a new apparatus to test the slash-proof materials used in soft protective armor or gloves. The apparatus can test the material with different cutting angles, different speeds, and various normal forces applied to the sample at the point of contact between the material and the cutting blade, with the capability to change all the parameters affecting the cutting force. This study aims to develop a cutting apparatus to study the cutting mechanism of textile materials with the capability to change all the parameters affecting the cutting force. The cutting angle and cutting speed have a significant effect on the maximum cutting force; however, the latter showed a high decrease of the maximum cutting force.

“…To simulate cutting, various practical and laboratory tests have been developed to assess cut resistance [5][6][7][8]. More recently, an international standard has been established to evaluate the cut performance of protective clothing materials [9,10] in which both a normal force and a sliding movement of a sharp object are reproduced. This standard test consists of sliding a blade on a sheet material under a given constant force and determining the blade displacement to cut through the thickness of the sheet.…”

Effect of Friction on Cut Resistance of Polymers

It is generally recognized that resistance to cutting consists of two aspects, one reflecting the intrinsic strength of the material, and the other a frictional contribution. In practice, cutting usually involves a normal force and a sliding movement. This work aims to analyze the effects of friction on cutting resistance of materials in the presence of a normal force and sliding movement of a sharp object. International Standard ISO 13997 is used as a reference to evaluate the cut resistance of some selected protective materials under practical conditions in service. The resistance to cutting of a material in the presence of both a normal force and sliding movement of a sharp object is strongly controlled by friction between the blade and the cut material. An increase in the friction coefficient can enhance or reduce the cut resistance, depending on the thickness, and the microstructure of the material to be cut. Thus the total energy required to propagate a cut strongly depends on the friction coefficient and consists of two components: The lost energy dissipated by the squeezing force exerted by the cut material, due to its elasticity, on the blade sides, and the essential cutting energy at the edge of the blade. These energies have opposite effects on the cutting resistance of materials. An increase in the energy dissipated in gripping frictional force increases the cut resistance, whereas an increase in friction at the blade’s edge reduces the energy required to cut the material.
