“…Although the surface roughness and the number of active groups of polyester fibers increase, the greater the roughness, the greater the number of active groups with destroyed crystallization and the more serious the damage to the fiber structure itself [ 17 ]. Laser modification can achieve the purpose of fiber surface activation, but instruments and equipment used in the process are complex in the requirements and high in the cost [ 18 ]. Chemical grafting method can protect the polyester fiber structure to maintain the original fiber strength, but also it can increase the interfacial cohesion of the aramid fiber surface.…”

Highly Strong Interface Adhesion of Polyester Fiber Rubber Composite via Fiber Surface Modification by Meta-Cresol/Formaldehyde Latex Dipping Emulsion

As a skeleton material, polyester (PET) fiber can significantly improve the strength and durability of rubber composites, but the interfacial adhesion between polyester fiber and rubber is poor due to the chemical inertia of PET fiber surface. Resorcinol-formaldehyde-latex (RFL) impregnating solution is usually used to treat PET fibers, but RFL contains toxic components such as resorcinol, which is harmful to the human body. A simple and less toxic resin-impregnating system cresol-formaldehyde-latex (CFL) was obtained by alternating resorcinol with low-toxicity cresol and m-cresol formaldehyde resin was synthesized from m-cresol and formaldehyde. CFL (m-cresol formaldehyde resin latex) systems with different C/F mole ratios and CF resin/latex ratios were adopted to modify the surface of PET fibers. The strip peeling adhesive and the H pull-out test results indicated that the PET fiber/rubber adhesion strength increased with the increase in the formaldehyde dosage and the CF resin content, and the peeling force value and the H-pull-out force of treated PET/rubber composites reached 7.3 N/piece and 56.8 N, respectively. The optimal choice of CFL adhesive system was obtained, when the C/F mole ratio was 1/2 and the CF resin/latex weight ratio was 0.23. This environment-friendly CFL dipping emulsion can be used as a new surface modification strategy as it can remarkably enhance the interfacial adhesion of PET/rubber composites.

“…Currently, there are several methods to investigate the interface properties in a single fiber and fiber bundle scale [7][8][9][10]. Generally, the single fiber push-out [11] and the pull-out tests [12][13][14] or the fiber bundle pull-out (FBPO) test [15][16][17][18] represent a fiber-loaded system. In these tests, the common measuring tests are carried out for a clamped matrix and therefore less suitable for elastic materials [19].…”

The focus of this paper is the realization and verification of a modified fiber bundle pull-out test setup to estimate the adhesion properties between threads and elastic matrix materials with a more realistic failure mode than single fiber debond techniques. This testing device including a modified specimen holder provides the basis for an adequate estimation of the interlaminar adhesion of fiber bundles including the opportunity of a faster, easier, and more economic handling compared to single fiber tests. The verification was done with the single-fiber and microbond test. Overall, the modified test setup showed the typical pull-out behavior, and the relative comparability between different test scales is given.

“…Laser cleaning is characterized by cleaning without changing the surface morphology, non-contact, high efficiency and suitable for various materials, and considered the most reliable and effective solution in many fields. Niroomand et al [10] used CO2 lasers to surface-treat tire molds and tire cords, improving the bonding performance and friction coefficient of tires, thereby reducing the risk of puncture. Takahashi et al [11] proposed a new concept of laser-assisted material removal that uses laser-assisted ultraviolet radiation to achieve nanoscale correction of microscopic three-dimensional (3D) objects.…”

Investigation on the Surface Properties of 5A12 Aluminum Alloy after Nd: YAG Laser Cleaning

et al. 2019

The surface of the aluminum alloy is prone to oxidation, which in turn affects the quality of the weld. The 5A12 aluminum alloy was cleaned by acousto-optic Q-switched diode-pumped Nd:YAG laser and the effects of different laser powers and different cleaning speeds on the surface roughness, microstructure, element content, microhardness, residual stress and corrosion resistance of aluminum alloy were investigated. The results show that when the power is 98W and the cleaning speed is 4.1 mm/s, the effect of Nd: YAG laser on the removal of oxide film on 5A12 aluminum alloy surface is the most effective. After laser cleaning, the smoothness and strength of aluminum alloy surface can be effectively improved. However, as a major element in 5A12 aluminum alloy, the content of magnesium decreased. At the same time, the residual tensile stress was generated on the surface of the aluminum alloy after cleaning, and the corrosion resistance slightly decreased.
