This paper investigated the tensile, bending, and impact response of aramid/glass hybrid weft-knitted reinforced composites. Homogeneous and hybrid composites with glass: aramid hybrid ratios of 1:1, 2:1, 3:1, and hybrid modes of transverse hybrid, oblique hybrid, and vertical interlocking hybrid were prepared by vacuum resin transfer molding (VARTM) technique. The tensile and bending properties were evaluated from stress, modulus, and strain/deflection, and a scanning electron microscope (SEM) was employed. The impact response was analyzed from peak force, maximum displacement, and energy absorption. The results confirm that interlacing brittle glass yarns with aramid yarns exhibits a positive hybrid effect. The ratios of 50%, 33%, and 25% aramid fiber in the transverse hybrid enhanced the longitudinal strength by 72.86%, 52.13%, and 22.01%. The mechanical properties of the oblique hybrid are similar in warp and weft direction; by contrast, the other two hybrid methods demonstrate mechanical anisotropy. This article implements the preparation and mechanical properties research of non-laminated hybrid composites based on weft-knitted structures, which broadens the design and selection of prefabricated components for hybrid composites.","PeriodicalId":16097,"journal":{"name":"Journal of Industrial Textiles","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42153291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Layered hybridisation of fabrics (i.e. glass, carbon, and Kevlar fabrics) is used to manufacture hybrid composite laminates by resin infusion via vacuum bagging method. The response of these materials to compression loading is investigated by using compression-loading testes and the load-bearing ability was examined by tensile strength tests. Moreover, finite element analysis has been carried out by using the Abaqus software to predict the compressive failure load and damage failure modes for all sockets samples. Experimental results revealed that the hybrid laminates exhibited more stability and higher absorbing energy compared to non-hybrid laminates during compressive loading tests. Furthermore, the hybridisation of fabrics layers can play key role for improving the tensile strength properties of hybrid composite laminates compared to composite laminates without hybridisation. The numerical simulation results of compressive failure load and damage failure modes are in accordance with experimental results qualitatively as well as quantitatively.","PeriodicalId":16097,"journal":{"name":"Journal of Industrial Textiles","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47504549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is of great importance to effectively remove antibiotics from wastewater. In this study, recyclable bacterial cellulose/sodium alginate/zeolitic imidazolate framework-8 (BC/SA/ZIF-8) aerogel composites were prepared by chemical cross-linking and in situ growth in freeze-drying. The successful preparation of the composite aerogel was confirmed by scanning electron microscope (SEM), Fourier Transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis. The results reveal that BC/SA/ZIF-8 aerogel composite has significantly high BET specific surface area of 165.24 m 2 /g than that of BC/SA at 7.39 m 2 /g. The BC/SA/ZIF-8 composite aerogel exhibited excellent adsorption performance for tetracycline hydrochloride, with a maximum adsorption capacity of 746.27 mg/g. The adsorption process followed the pseudo-second-order kinetic model and Langmuir adsorption isotherm model. Moreover, the reusability test on BC/SA/ZIF-8 composite aerogel revealed an insignificant decline in adsorption after six cycles. Therefore, BC/SA/ZIF-8 composite aerogel has a high potential as a novel and recyclable adsorbent for efficient removal of tetracycline hydrochloride from water.","PeriodicalId":16097,"journal":{"name":"Journal of Industrial Textiles","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136302259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five samples, with varying percentages of loops and tuck loops, were designed. The results indicated that the sensor demonstrated a GF of 2.80 kPa −1 at the Lx-axis and 3.67 kPa −1 at the Ly-axis, showing good repeatability during 1000 cycles of stretch/release. Moreover, it exhibited fast responsiveness, enabling it to discriminate between different rates of stretch.

Acoustic emission provided a convenient method for obtaining fibers breaking elongation distribution. Based on the fiber bundle model and fiber breaking distribution, the fracture strength and elongation of bundle fibers could be predicted. Meanwhile, based on the correlation between the amplitude of fiber fracture sound and fiber breaking strength, the single fiber breaking strength could be predicted and the tensile properties of bundle fibers could also be obtained. The prediction results based on bundle fiber fracture sound were more similar to the measured results. Besides, the number of fibers within the bundle increased, the fiber interaction was also enhanced, and the bundle fiber strength prediction results were affected.

Natural fibers are becoming increasingly popular as a renewable and biodegradable resource. In this study, we prepared a kapok/waste silk nonwoven (KSN) by wet-laid and hot-pressing, which had adequate mechanical strength, hydrophilic, lipophilic, and biodegradable properties. The effects of the kapok fiber proportion on the morphology, air permeability, softness, mechanical property, wettability, and biodegradability of KSN were studied. The results demonstrated that the thickness, porosity, air permeability, and softness decreased as the proportion of kapok fiber increased. The mechanical property was significantly enhanced, and the breaking strength increased from 0.58 MPa to 10.85 MPa. With the increase in the proportion of kapok fiber, the spreading time of oil and water increased and decreased respectively, and the static contact angles were below 50°. Degradation rate improved with the increase of kapok fiber proportion, with a maximum degradation rate of 49.41% (30 days). Therefore, the multifunctional, low-cost, easily prepared, and biodegradable kapok/waste silk nonwovens is a promising bio-based material with superior application prospects in dressings, facial mask substrate, packaging, and related fields.","PeriodicalId":16097,"journal":{"name":"Journal of Industrial Textiles","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135798504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the effects of different preparation processes on the tensile strength, static puncture resistance, and tear strength of flexible composites were investigated in this paper. The results indicated that both hot-pressing temperature and vulcanization time had a significant impact on the mechanical properties of the composites. With an optimum vulcanization temperature of 185°C and a vulcanization time of 10 min, the composite provides optimum tensile strength and puncture resistance. Tear strength is the worst and is related to the reinforcement’s organisational structure and the interfacial bond’s strength.
