Synthetic high-performance fibers present excellent mechanical properties and promising applications in the impact protection field. However, fabricating with high strength toughness is challenging due to their intrinsic conflicts. Herein, we report a simultaneous improvement strength, toughness, modulus of heterocyclic aramid by 26%, 66%, 13%, respectively, via polymerizing small amount (0.05 wt%) short aminated single-walled carbon nanotubes (SWNTs), achieving tensile 6.44 ± 0.11 GPa,...
High dynamic strength is of fundamental importance for fibrous materials that are used in high-strain rate environments. Carbon nanotube fibers one the most promising candidates. Using a strategy to optimize hierarchical structures, we fabricated carbon with 14 gigapascals (GPa) and excellent energy absorption. The performance attributed simultaneous breakage individual nanotubes delocalization impact occurs during loading process; these behaviors due improvements interfacial interactions,...
Abstract Poly(p‐phenylene‐benzimidazole‐terephthalamide) (PBIA) fibers with excellent mechanical properties are widely used in fields that require impact‐resistant materials such as ballistic protection and aerospace. The introduction of heterocycles polymer chains increases their flexibility makes it easier to optimize the fiber structure. However, inadequate orientation is one main reasons for large difference between measured theoretical PBIA fibers. Herein, carbon nanotubes (CNTs)...
Abstract As a typical kind of high‐performance fibers, heterocyclic aramid fibers are widely used to reinforce resins prepare advanced lightweight composites with high mechanical performances. However, their poor interfacial shear strength limits the combination and leads undesirable composites. Thus, tensile highly desired. Herein, 40.04 ± 2.41 MPa 5.08 0.24 GPa reported, in which nitrile‐modified poly‐(benzimidazole‐terephthalamide) polymer chains crosslinked by azide‐functionalized...
Liquid crystal wet-spun carbon nanotube fibers (CNTFs) offer notable advantages, such as precise alignment and scalability. However, these CNTFs usually suffer premature failure through intertube slippage due to the weak interfacial interactions between adjacent shells bundles. Herein, we present a microwave (MW) welding strategy enhance by partially carbonizing interstitial heterocyclic aramid polymers. The resulting exhibit ultrahigh static tensile strength (6.74 ± 0.34 GPa) dynamic (9.52...
Abstract It has been a vital issue to ensure both the accuracy and efficiency of computational models for analyzing ballistic impact response fiber-reinforced composite plates (FRCP). In this paper, machine learning (ML) model is established in an effort bridge protective performance characteristics microstructure unidirectional FRCP (UD-FRCP), where UD-FRCP characterized by two-point correlation function. The results showed that ML model, after trained 175 cases, could reasonably predict...
High-performance fiber-reinforced composites (FRCs) are widely used in bulletproof structures, which the mechanical properties of single fibers play a crucial role ballistic resistance. In this paper, quasi-static and dynamic three commonly fibers, aramid III, polyimide (PI), poly-p-phenylenebenzobisoxazole (PBO) measured by small-scale tensile testing machine mini-split Hopkinson tension bar (mini-SHTB), respectively. The results show that PBO fiber is superior to other two terms strength...
In this study, the traditional mini split Hopkinson tension bar (SHTB) was enhanced for dynamic mechanical performance testing of single fiber/resin interface composites. Single Aramid III fibers were modified using a polyamine modification treatment. Quasi-static and tensile tests conducted an electronic machine SHTB. The test results indicated that surface employing Catechol-Tetraethylenepentamine (Cat-TEPA) approach had negligible effect on properties fibers. microdroplet method...
The aim of this study was to investigate the association methylenetetrahydrofolate reductase (MTHFR) gene polymorphism and additional gene-gene interaction with acute lymphoblastic leukemia (ALL) risk. Logistic regression performed between two single nucleotide polymorphisms (SNPs) within MTHFR ALL risk rs1801133 rs1801131. minor allele rs1801131 is associated decreased risk, OR (95% CI) were 0.61 (0.38-0.89), 0.68 (0.50-0.96), respectively. We also found a significantly SNPs, participants -...
Intestinal duplication is a rare congenital disease. Its clinical manifestations are nonspecific, and preoperative diagnosis difficult. Gastrointestinal angiography, ultrasound, CT often used to detect this A case of small intestinal can be diagnosed through 99TcmO4− imaging. The advantages radionuclide imaging have been emphasized in literature. It diagnose help identify causes lower gastrointestinal bleeding children.
Abstract Synthetic high-performance fibers, such as polyaramid have attracted particular attention owing to their excellent mechanical properties and promising applications in safety protection fields. However, fabricating fibers with high strength toughness is challenging due intrinsic conflicts. Herein, we report a simultaneous improvement of heterocyclic aramid by 26% 66%, respectively, via situ polymerizing small amount (0.05 wt%) short aminated single-walled carbon nanotube (SWNT) into...
