“…This phenomenon may be comparable with the failure mode of G3-type beam. The experimental results show that the concrete with nonwoven geotextile fabric was highly ductile in nature, as supported by the study of Claramunt et al [21]. This concrete's flexural strength and toughness could be more enhanced if an additional layer of nonwoven geotextile was used.…”

Strengthening of Reinforced Concrete Beam (RCB) for enhancing its flexural performance is a very popular technique to increase the structural life span. Optimization of the construction and strengthening cost without compromising the target strength and service life of a structure is now a matter of challenge for researchers. The wire mesh and geotextile materials possesses some good properties, such as cost-effectiveness, high strength-to-weight ratio, significant flexural performance, and compatibility with concrete, thus can be used as strengthening material. This experimental study aimed to investigate wire mesh and geotextile as strengthening materials for RCBs to enhance their flexural capacity. Three different types of strengthening configuration were used for each type of strengthening material. In order to examine the effectiveness of the wire mesh and geotextile as strengthening material, three point bending tests were done. This experimental results showed that the beams wrapped using wire mesh could enhance the flexural performance and reduce the deflection of RCBs without damage up to the reliable limit. Moreover, wire mesh layer in the tension face and U-wrapping system were proven as the effective configuration in the strengthening technique. The nonwoven geotextile strengthened-beams also had a moderate strength compared with wire mesh strengthened-beams. Nevertheless, the RCBs were found to be more flexible in nature, having a grip on concrete after failure occurred in concrete crushing when wrapped with geotextile layer. Therefore, RCB strengthening by incorporating wire mesh and geotextile materials is sustainable in terms of structural integrity and economic aspect.

“…High deformability of polypropylene fibers may enhance this behavior. The deformability of this fabric is higher than 30% [21]. A 0-91% increase in ultimate load carrying capacity was found in the experiment, which depended on the arrangement of strengthened layers (Table 4).…”

“…Then, the layers were piled alternating the nonwoven direction (machine and cross direction) in a mold specially designed to apply a 3.5 MPa homogeneous pressure, pressure that was kept for 24 h. Then, the composites were cured in a humidity chamber (approximately 95% relative humidity, 20 � C) for 28 days. For further details, the procedure is described in previous papers [3,28].…”

The aim of this paper is to evaluate the influence of sustainable surface treatments-performed on flax nonwoven fabrics as textile reinforcement-on the durability of calcium aluminate cement (CAC) based composites. Two treatments are considered: an alkaline treatment (for increased stability and adhesion), and a treatment with soybean oil (to reduce fiber degradation). The cement hydration was studied by analysis of backscattered scanning electron microscopy images, which revealed variations nearby the fibers owing their capacity for water absorption and presence of oil on the surface. A retarding effect on cement hydration was observed on the composites prepared with the oil-treated fabrics. The composites containing the alkali treated fabrics had better mechanical properties and also the highest durability. For these composites it was found an optimized fiber-matrix adhesion and penetrability of the cement to the fabric.

“…In the literature, many studies have reported the measurement of mechanical and thermal properties of polymeric materials, including textile fabrics [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. Darden and Schwartz proposed a framework to draw correlations between human sensory outcomes, such as smoothness and leather-like feel, and quantitative physical properties, such as friction coefficient and elastic modulus, for polymer fabrics [ 19 ].…”

“…This method had the advantage of having an application in strain sensing and structural health monitoring by obtaining the electro-mechanical properties of the polymeric composite sensor. Claramunt et al developed a process to produce high-performance cement-based composites, reinforced with flax nonwoven fabrics, and took advantage of flexural and direct tension tests for analyzing the influence of the fabric structure—thickness and entanglement—on mechanical behavior [ 23 ]. These test methods and instruments helped with the development of the integration measurement of mechanical and dynamic heat transfer properties of porous polymeric materials.…”

Simultaneous Contact Sensing and Characterizing of Mechanical and Dynamic Heat Transfer Properties of Porous Polymeric Materials

Porous polymeric materials, such as textile fabrics, are elastic and widely used in our daily life for garment and household products. The mechanical and dynamic heat transfer properties of porous polymeric materials, which describe the sensations during the contact process between porous polymeric materials and parts of the human body, such as the hand, primarily influence comfort sensations and aesthetic qualities of clothing. A multi-sensory measurement system and a new method were proposed to simultaneously sense the contact and characterize the mechanical and dynamic heat transfer properties of porous polymeric materials, such as textile fabrics in one instrument, with consideration of the interactions between different aspects of contact feels. The multi-sensory measurement system was developed for simulating the dynamic contact and psychological judgment processes during human hand contact with porous polymeric materials, and measuring the surface smoothness, compression resilience, bending and twisting, and dynamic heat transfer signals simultaneously. The contact sensing principle and the evaluation methods were presented. Twelve typical sample materials with different structural parameters were measured. The results of the experiments and the interpretation of the test results were described. An analysis of the variance and a capacity study were investigated to determine the significance of differences among the test materials and to assess the gage repeatability and reproducibility. A correlation analysis was conducted by comparing the test results of this measurement system with the results of Kawabata Evaluation System (KES) in separate instruments. This multi-sensory measurement system provides a new method for simultaneous contact sensing and characterizing of mechanical and dynamic heat transfer properties of porous polymeric materials.
