The static and tensile fatigue properties of cross-ply high-strength polyacrylonitrile (PAN)-based carbon (T800SC) fiber-reinforced epoxy matrix composites (CFRPs) with thin ply thickness were studied. The fiber orientations of the CFRP specimens were set to cross-ply with [0/90]10S (subscript S means symmetry), [(0)5/(90)5]2S, and [(0)10/(90)10]S. The static and tensile fatigue characteristics of cross-ply CFRPs with thick ply thickness with [0/90]2S and [(0)2/(90)2]S were also investigated for comparison. Under static loading, the tensile strength and failure strain of thinnest 90° ply CFRP specimens were higher than those of other 90° ply thickness ones. But, the tensile modulus and Poisson’s ratios were comparable among the cross-ply CFRP with thin and thick ply thickness specimens. Under fatigue loading, the fatigue response of thinnest 90° ply CFRP specimens were higher than those of other 90° ply thickness ones for lower fatigue cycle testing (< 105 cycles). Though, for higher fatigue cycle testing (> 105 cycles), the fatigue responses decreased with a decrease in the 90° ply thickness and the fatigue characteristics of the thinnest 90° ply CFRP specimen were lower than those of other cross-ply CFRP thin and thick ply thickness specimens.

“…The tensile strength of BEZ4 and BEZ5 composites reduce by 5.76% and 12.54% respectively when compared with the tensile strength value of the unfilled BEZ0 laminate. This can be attributed to the fact that tensile strength is a fiber dominated property[60] and the modification of the epoxy matrix through the inclusion of ZnO nanofillers has little to no effect in improving the tensile strength of the BEZ composites.To further understand the behavior of BEZ composites under tensile loading, it is important to study the elongation at break or the fracture strain. This generally gives the ability of the fibers to resist deformation under loading.…”

Hybridization effect on the mechanical properties of basalt fiber reinforced ZnO modified epoxy composites

et al. 2022

This paper discusses the fabrication of nano ZnO filled epoxy/basalt fiber composites and investigates the effect of such hybridization on the mechanical properties of the composites. The epoxy resin is modified by the addition of ZnO nanofiller in different wt.% (1-5 wt%). The dispersion of the nanofiller within the epoxy resin is brought about by sonication technique. The composites are fabricated through wet layup followed by curing under compression molding. To ascertain the effect of resin modification, flexural and tensile strengths are evaluated. The inter-laminar shear strength (ILSS) is determined to identify the compatibility of the ZnO nanofiller with the epoxy and the basalt fibers. The improvement in the ILSS indicates thorough wettability being achieved between all the composite components. The addition of ZnO nanofiller improved the flexural strength, while there was no remarkable improvement in the tensile strength of the ZnO modified epoxy/baslat (BEZ) composite. Maximum improvement in the strengths is observed for BEZ2 composite with 2 wt% of ZnO nanofiller. For BEZ2 composite, the flexural and tensile strength increased by about 22% and 9.78% respectively in comparison to unfilled BEZ0 composite. The ILSS for BEZ2 composite improved by 21.74% in comparison to BEZ0 composite. In addition, more than 2 wt% addition of the ZnO nanofiller resulted in the reduction of flexural, tensile and ILSS of the composite due to agglomeration. Such agglomeration resulted in the failure of the composite due to delamination, matrix cracking and fiber fracture as observed through scanning electron microscopy images of the fractured composites.

“…Basalt fiber is made of natural ore after melting and spinning at a high temperature. As basalt fiber is environmentally friendly and stable, it has gradually become an important fiber material in industrial production [7][8][9]. Many studies have confirmed that basalt fiber and its composites have better mechanical properties and stability than glass fiber and its composites.…”

As basalt fiber has better mechanical properties and stability than glass fiber, cross arms made of continuous basalt-fiber-reinforced epoxy matrix composites are capable of meeting the mechanical requirements in the event of typhoons and broken lines in coastal areas, mountainous areas and other special areas. In this paper, continuous basalt-fiber-reinforced epoxy matrix composites were used to fabricate the core rods and composite cross arms. The results verified that basalt fiber composite cross arms can meet the strict requirements of transmission lines in terms of quality and reliability. In addition to high electrical insulation performance, the flexural modulus and the flexural strength of basalt fiber core rods are 1.8 and 1.06 times those of glass fiber core rods, respectively. Basalt fiber core rods were found to be much better load-bearing components compared to glass fiber core rods. However, the leakage current and the result of scanning electron microscopy (SEM) analysis reveal that the interface bonding strength between basalt fibers and the matrix resin is weak. A 3D reconstruction of micro-CT indicates that the volume of pores inside basalt fiber core rods accounts for 0.0048% of the total volume, which is greater than the 0.0042% of glass fiber rods. Therefore, improving the interface bond between basalt fibers and the resin can further improve the properties of basalt fiber core rods.
