Effect of Glass Fibers Stacking Sequence on the Mechanical Properties of Glass Fiber/Polyester Composites

Abstract

The objective of this work is to compare the mechanical properties including tensile, bending and impact properties between different glass fiber architecture reinforced polyester composites which are fabricated by a hand lay-up technique. The effects of stacking sequences of glass fibers consists of five layers which mainly are plain woven, short fiber, and sandwich layer glass composites on the mechanical properties of composites have been studied. The results showed that the tensile and bending properties of all different composite laminates are significantly higher compared to the neat resin. The plain woven glass reinforced polyester composites showed the highest values compared with other composite laminates. As the glass fiber mats a core are tightly packed and absorbs the impact stresses and distributes them evenly in the composites sandwich layer, the glass composites showed the highest value of impact strength compared with other composite laminates. Moreover, from SEM investigations, in these composites, there is an inverse relationship between the amount of delamination and the amount of hackles, and as the hackles increase the mechanical properties including tensile and bending of these composites are enhanced.

Suitable stacking sequence of glass fibre reinforcements for specific application of composite using Taguchi design and finite element method

“…The longer length glass fibre filament based reinforcements offered higher tensile and flexural strength as observed in the study of Elbadry et al on glass fibre chopped strand mat and woven mesh reinforced composites. 17 The tensile fracturograph of chopped strand mat based composite is shown in Figure 9(e).…”

“…The mechanical properties 4 of composites are primarily determined by the strength of the fibre, the strength of the matrix, the chemical stability of the matrix, the ability of the fibre matrix interface to transfer stress, the orientation of a specific type of reinforcing material, the length distribution of the fibre, the cross sectional area of the fibre, and the stacking sequence of different reinforcing layers in multi-layer composites. 3,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] The literature review reveals that the focus of glass fibre composite research is on (i) the use of various forms of glass fibre reinforcement in combination with different resin systems and their mechanical response 2,21,22 (ii) the use of hybrid reinforcements in the manufacture of glass fibre composites [11][12][13][14][15][16][17][18]23 and (iii) the influence of stacking angle of reinforcing materials in composites on their desired applications and purposes. 24 Any structural component experiences multidirectional load during use.…”

Effect of Glass Fiber Stacking Sequence on the Notch Sensitivity of Glass Fiber Reinforced Epoxy Matrix Composites

“…Glass fiber reinforced unsaturated matrix was fabricated using the traditional hand lay-up method. In this method, the polymer or epoxy resin after mixing with the hardener was poured on the mold plate and the first layer of woven glass fiber was impregnated with the resin and the details were reported by Elbadry et al [34]. The volume fraction of fiber was determined according to the ignition loss method according to ASTM D2548-68.…”

“…From the literature review, only few studies have been investigated the effect of stacking sequence of plain woven glass fiber on the notch sensitivity of glass woven composites. Recently, the authors have studied the notch sensitivity of short and 2D plain-woven glass fibres reinforced with unsaturated polyester and epoxy matrix composites [34], Therefore, the objective of this work is to investigate the effect of stacking sequence of plain woven glass fiber on unnotched tensile strength and the notch sensitivity of glass fiber reinforced epoxy matrix composites. The notch sensitivity is based as on the residual tensile strength (ratio of notched to unnotches tensile strength) through open hole tension test with different ratios of the specimen hole diameter to the specimen width (D/W) with three different values (0.1, 0.2, 0.5).…”

Multiscale nanocomposites and laminates reinforced by carbon nanotubes and fibres

“…It is assumed that the matrix fills up all the voids and cavities within the RVE. For the sake of this analysis the hexagonal pattern was opted for because of its ability to accurately represent the transverse isotropy of the nanotubes as opposed to a square stacking sequence (Elbadry et al 2018). The hybrid composite can be altered by varying the volume fraction of both the CNTs and fibre reinforcement within the epoxy matrix to achieve desired material properties.…”
