High-performance fiber-reinforced cement composites (HPFRCCs) are characterized by strain-hardening and multiple cracking during the inelastic deformation process, but they also develop high shrinkage strain. This study investigates the effects of replacing Portland cement with calcium sulfoaluminate-based expansive admixtures (CSA EXAs) to compensate for the shrinkage and associated mechanical behavior of HPFRCCs. Two types of CSA EXA (CSA-K and CSA-J), each with a different chemical composition, are used in this study. Various replacement ratios (0%, 8%, 10%, 12%, and 14% by weight of cement) of CSA EXA are considered for the design of HPFRCC mixtures reinforced with 1.5% polyethylene (PE) fibers by volume. Mechanical properties, such as shrinkage compensation, compressive strength, flexural strength, and direct tensile strength, of the HPFRCC mixtures are examined. Also, crack width and development are investigated to determine the effects of the EXAs on the performance of the HPFRCC mixtures, and a performance index is used to quantify the performance of mixture. The results indicate that replacements of 10% CSA-K (Type 1) and 8% CSA-J (Type 2) considerably enhance the mechanical properties and reduce shrinkage of HPFRCCs.

Self-reboot-mobility of self-cleaning antimicrobial industry on textiles and apparel is receiving an increasing amount of interest worldwide as a method to address Antimicrobial in materials. In particular, for advanced high-performance fiber-reinforced polymer of self-reboot-mobility (SRM) with composite materials, Self-reboot-mobility of self-cleaning antimicrobial industry on textiles and apparel offers an alternative to employing conservative damagetolerant designs and a mechanism for ameliorating inaccessible and invidious internal Antimicrobial within a structure. This article considers in some detail the various self-reboot-mobility of self-cleaning antimicrobial industry on textiles and apparel technologies currently being developed for SRM with composite materials. Key constraints for incorporating such a function in SRMs are that it not be detrimental to inherent mechanical properties and that it not impose a severe weight penalty

In this paper, mechanical properties of three series of high performance fiber reinforced concrete (HPFRC) containing 1, 2 and 3% of Polyvinyl Alcohol (PVA) fiber volume are presented. The first series of HPFRC was prepared by using 100% cement, whereas remaining two series were prepared by replacing 10% cement content with silica fume and locally produced metakaolin. All series were designed with water to binder ratio (w/b) of 0.4. The mechanical properties determined in this study include compressive strength, splitting tensile strength and flexural strength. Testing of the specimens was conducted at the 28 days of curing. Experimental results showed that the 3% PVA fiber is the optimum fiber volume to improve the mechanical properties of HPFRC. The variation in the mechanical properties due to the addition of PVA fibers was investigated and presented in the form of mathematical relationship. Further, interrelationship among the mechanical properties was also determined.

Natural fiber reinforced polymer composite is a much focused area of study owing to its environmentally friendly nature and good mechanical properties. These composites offer comparable mechanical properties to that of steel and other composite materials. Dynamic mechanical analysis is a widely used technique to investigate the mechanical performance of fiber reinforced composites at a wide range of temperatures. Using this technique, the thermal transitions and damping properties of fiber reinforced composites too can be studied. These natural fiber composites are widely employed in structural applications in many industries. Here, in this short review we have presented the recent works on the dynamic properties of natural fiber reinforced composite materials with an essence of the influencing factors.

In this work we investigated the application of a novel high performance polymer, polybenzoxazine, as a polymeric matrix in Fiber Metal Laminates (FML). This polymer, when applied on the development of FMLs, generated higher mechanical properties in comparison to fiber metal laminates obtained with epoxy. To investigate the mechanical performance of the polybenzoxazine matrix in FMLs, a mechanical behavior comparison was carried out among epoxy matrix laminates - glass fiber reinforced aluminum laminate (GLARE) and carbon fiber reinforced aluminum laminate (CARALL) - and FML constructed with aluminum and carbon fiber reinforced polybenzoxazine. The mechanical properties were characterized by drop weight impact and flexural methods, and the polybenzoxazine curing behavior through differential scanning calorimetry (DSC). Polybenzoxazine FML generated increasing of: 18% of maximum load, 11% of maximum elongation under flexure and 7.5% of impact energy absorption compared to other fiber metal laminates.

Green high-performance fiber-reinforced cement (GHPFRC) matrix composite is prepared by mixing matrix composites like slurry, mortar, or concrete with reinforcing materials like metal or inorganic nonmetal fiber, synthetic fiber, or natural organic fiber by a certain method. This composite is more energy-efficient, ductile, low-carbon, economic, and environmentally friendly than ordinary concrete. However, the performance of GHPFRC matrix composite has not been fully studied. The existing research only deals with the seismic performance and fire resistance of the material, failing to systematically discuss the optimal mix ratio. To solve the problem, this paper presents an optimization strategy for multielement GHPFRC matrix composite, and carries out multiple tests on its basic mechanical performance, toughness, impact resistance, shrinkage cracking, dry shrinkage performance, and durability. The test data on various indices verify the superior performance of the prepared multielement GHPFRC matrix composite. Further, the optimal mix ratio of the material was determined as: 60% cement, 30% fly ash, and 10% silica ash, with the water-cement ratio of 0.4, water reducer dosage of 1.5%, and quartz sand dosage of 500g.
