“…Hence, the use of basalt fibers for the fabrication of composite materials and the determination of their mechanical properties have attracted considerable attention in recent years. The tensile, compression, flexural, impact, creep, abrasive wear, fracture, and interlaminar shear strength properties of basalt fiber reinforced composites have been explored in a number of researches , and there are several numbers of researches related with the incorporation of basalt fibers with the fibers of other reinforcement materials, such as glass , carbon , nylon , aramid , hemp , jute , glass/flax , glass/hemp , flax/hemp . Compared to those of neat glass, carbon, nylon, jute, hemp and aramid fiber composites, improvements in impact strength and energy absorption were reported for the basalt/glass , basalt/carbon , basalt/nylon , basalt/jute , basalt/hemp , and basalt/aramid hybrid composites, respectively.…”

Basalt/aramid hybrid fiber reinforced composite laminates were prepared to examine the effect of hybridization on Charpy impact behavior of aramid fiber reinforced composite laminates. The effect of position of basalt layers on the impact behaviors was also investigated by preparing hybrid composite laminates with the substitution of basalt layers into different positions. The position change of basalt layers in the hybrid configurations were resulted in variations in the impact behavior. The impact energy and impact damages strictly depended on impact behavior of fiber at impacted surface due to the difference between deformation characteristics of basalt fiber and aramid fiber. When the basalt layer was at the impacted surface, the hybrid composite laminates exhibited a lower impact energy. This was attributed to the restriction in deformation of aramid layers. The position of basalt layers resulted in variations in the impact behavior of hybrid composite laminates. POLYM. COMPOS., 39:467–475, 2018. © 2016 Society of Plastics Engineers

“…6 Compared to CFRP, BFRP possesses a very similar high temperature working ability at a lower cost, thus making BFRP a strong competitor in some applications. [7][8][9] In addition, the hybridization of fibers with different characteristics is commonly used for designing composite structures to achieve ductility or stiffness requirements. Thus, because of the promising BFRP and potential hybrid applications, an investigation of the interlaminar shear behavior of BFRP and hybrid FRP layered laminates is the emphasis of the current research.…”

This paper focuses on the interlaminar shear behavior of basalt fiber reinforced polymer (FRP) laminates impregnated with epoxy and vinyl ester resins as well as hybrid basalt and carbon FRP laminates. Meanwhile, the interlaminar shear behavior of carbon and E-glass FRP laminates was also studied for comparison. The experiments were conducted according to the ASTM-D-2344 standard, and the failure modes, load-deformation (L-D) relationships, and interlaminar shear stress to normalized deformation relationships of various FRP laminates were analyzed. The differences in interlaminar shear behavior among different fibers and resins were identified. The fracture surfaces of the laminate specimens with different fibers were examined by scanning electron microscopy. Furthermore, the hybrid effect on interlaminar shear behavior was discussed and the interlaminar shear strength was predicted based on above analysis. The results show that the L-D relationships of FRP laminates can be classified into three types, which are determined by the interlaminar shear strength between fiber layers and the resin as well as by the failure modes. The interlaminar shear strength of basalt FRP with vinyl ester resin is higher than that of the glass FRP but less than that of the carbon FRP. The adoption of epoxy resin and the hybridization of basalt and carbon fibers can enhance the interlaminar shear strength of basalt FRP. In addition, the scanning electron microscopy images of fracture surfaces of the laminate specimens confirm the differences of interlaminar behavior of various composites. The hybrid effect on the interlaminar shear behavior is reflected in the integration of both advantages of basalt FRP and carbon FRP in the interlaminar shear stress to nominal deformation relationship, which results in both higher interlaminar shear strength at the cracking and the final stages. Finally, the interlaminar shear strength of different FRP laminates can be accurately predicted by the proposed model.

“…Generally, the larger the CV value is, the greater the variability is in the data [37]. It has won its advantages in cross concept analysis and been widely applied in biomedicine, environmental analysis, manufacturing, dynamics study and many other fields [38][39][40][41][42][43]. The traditional analysis based on standard deviation (SD) reflects the degree of fluctuation of a random variable.…”

Green building is an inevitable trend in the construction industry which deeply affects the social development of the economy, environment and a series of industries. There is practical significance for the multidimensionally balanced development of green buildings. A model for multi-objective assessment of green building is developed under three dimensions: Objective, Professional and Time (OPT) according to the green building definition. The OPT coordinate system was built up based on the scoring centroid system of both the China Green Building Labelling scheme (GBL) and the Singapore Green Mark (GM) by the introduction of the Coefficient of Variation and Moment of Inertia. Both these frameworks are restructured based on a case study of a practical project in Chongqing which had achieved the highest GBL and GM awards. Results show that GBL distributes its scores more evenly while GM concentrates on energy saving with greater diversity in land supply and building operations (normalized coefficients of variation of 0.435 and 0.350). The project's compliance coefficients are 1.27 and 0.31 under GBL and GM respectively indicating its higher degree of compliance with the GM framework. The developed model provides multitarget-oriented guidelines for green building design, assessment and standarddevelopment.
