“…Typically, many works have been done to evaluate the ILSS of conventional carbon, glass, and Kevlar and Basalt FRP composites. [8][9][10][11][12][13] Wang et al 13 presented a comparative investigation of the ILSS between conventional GFRP, CFRP, BFRP, and the hybrid basalt/ carbon fiber reinforced polymer (BCFRP) laminates impregnated with epoxy or vinyl ester resins. They concluded that the ILSS of BFRP with vinyl ester resin is higher than that of GFRP but less than that of CFRP.…”

The present article investigates the interlaminar shear strength of the woven carbon, glass, and Kevlar fiber reinforced epoxy (CFRE, GFRE, and KFRE) composites filled with SiC particles. The work covers the samples preparation, testing, and analyzing. The samples were fabricated using the regular addition of the SiC particles as 0, 5, 10, 15, and 20 wt% of the total weight of epoxy resin. Samples of the short beam shear test were cut using CNC machine. The experiments were conducted according to the ASTM-D-2344 standard. The fracture surfaces of the laminate samples were observed by scanning electron and optical microscopy. The major benefits of the current study are that the modification process by adding a certain amount of the SiC particles significantly enhanced the interlaminar shear strength of CFRE, GFRE, and KFRE composites as the comparison to the conventional ones.

“…2,[10][11][12][13][14][15][16][17][18]19 Previous researches have mainly focused on the impact factors and enhancement of the ILSS for designed composites and concluded that the surface state is the most critical factor for controlling the ILSS of CFRP and GFRP, while the influences of different fibers were also observed. [10][11][12][13][14] Furthermore, the ILSS can obviously be enhanced by resin modification and hybridization. For instance, through the injection of multiwalled carbon nanotube (MWCNT)-epoxy suspensions into stationary glass Eber mats, the interlaminar shear behavior was obviously enhanced.…”

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.

“…The details for the measurement of interlaminar shear strength can be found in the literature. 11 It was found that the interfacial shear strength of P-S2 was slightly higher than that of other specimens, which might be associated with the conversion of sizing from polymeric state to glassy state. In particular, the interfacial shear strength of P-5 specimen was about three times lower than that of P-1 specimens.…”

“…In our previous work, it was found that the FMA could be modified by thermal treatment. 10,11 Therefore, to gain an insight into how the FMA at CFRP stage affects the microstructure and mechanical properties of C/C-SiC composite, the FMA was modified by thermal treatment of carbon fiber at different temperatures. The microstructure at each stage was characterized to reveal the mechanisms for the varied microstructure and mechanical properties of C/C-SiC composite.…”

In order to understand the role of fiber–matrix adhesion (FMA) at carbon fiber‐reinforced polymer (CFRP) stage on the microstructure and mechanical properties of C/C–SiC composite via liquid silicon infiltration (LSI) process, the FMA was adjusted by thermal treatment of carbon fibers at different temperatures and evaluated by means of single fiber push‐out technique. The microstructure was characterized by optical microscopy and scanning electron microscopy. The mechanical properties were measured by the double‐notched shear test, three‐point flexural test, and single edge‐notched beam test, respectively. Results indicated that the microstructure and mechanical properties of C/C–SiC composite via LSI were closely associated with the FMA at CFRP stage. The microstructure of C/C–SiC composite fabricated by using the CFRP with high FMA presented nonhomogeneous distribution and concentration of SiC matrix. In contrast, the C/C–SiC composite fabricated by using the CFRP with low FMA, the high content of SiC distributed homogeneously and surrounded the fiber, which resulted in a strong bonded C–SiC interface. The strong C–SiC interface is detrimental to the fracture toughness, but it is beneficial to the improvement of oxidation resistance. To obtain desired mechanical properties of C/C–SiC composite, the control of interface bonding is important, which can be realized by modifying the FMA at CFRP stage.
