Mechanical properties of composite material laminates reinforced by woven and non-woven glass fibers

Abstract

The purpose of this work is to study the mechanical characteristics in 3-point bending and in traction; static; and the impact behavior of three specimens of laminates made of glass fiber and polyester resin non-woven and woven, with the aim of using them in the repair of boat hulls and enhancing their value in the naval industry. Three types of laminates were developed by contact molding. These different specimens of laminates made of woven, non-woven and combined glass fiber (woven and non-woven) were subjected to mechanical tests (traction and 3-point bending). Analysis of the results of the tests carried out on these three types of laminate shows that one specimen stands out and gives higher mechanical performance than the othertwo.

“…and are comparable with UDMA and BFEP [28,39,40]. However, they have lower measured values compared to GFEP, GFPU840871, GFPU 90IK01, Glass laminated PE [12,28,32,34].…”

“…Mekane-selam has a 6% and 5% higher tensile modulus than Kom-bolcha in Feb. and Nov., respectively. As indicated in Table 2, the tensile modulus of the BFEPCs of Inji-bara, Kom-bolcha, and Mekane-selam have higher measured values compared to GFEP, Jute felt PU, CFPU, GFMPU, BFPP, BFEP, GFEP, pp foam, GFPU, Glass laminated [3,7,12,15,35], and are comparable with GFPU840871, and GF laminated PE [32,34]. However, they have lower measured values compared to GFPU 90IK01 and TPU [30,36].…”

“…Inji-bara, Mekane-selam, and Kombolcha have the highest to the lowest tensile strengths, respectively. As indicated in Table 2, BFEPCs of Inji-bara, Kom-bolcha, and Mekane-selam have higher tensile strength compared to Jute felt PU (polyurethane), CFPU (carbon fibres polyurethane), GFPU (glass fibres polyurethane), BFPP, BFEP, PP foam, and TPU (thermoplastics polyurethane) [7,15,[25][26][27][28][29][30][31], and are comparable with BFEP, GFPU, and GF laminated with PE (polyester) [3,28,32].

“…They exhibit high stiffness and mechanical strength, have good damping properties, and possess high impact toughness. Additionally, their low coefficient of thermal expansion, wear resistance, high flexibility, corrosion resistance, and ability to maintain properties at high temperatures are crucial features [6][7][8]. These properties have made composite materials a key element in creating robust, lightweight, and durable structures across various applications.…”
