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.
Highlights
In recent years, the composite materials processing industry has enjoyed rapid and steady growth, supported in particular by the diversity of applications [1,2]
Influence of the type of reinforcement: - specimen No 1, the laminate reinforced with woven type glass fibers has a maximum stress of 0.465 GPa and an elastic modulus of 29.645 GPa. - specimen No 3, the laminate reinforced with non-woven type glass fibers has a stress of the order of 0.279 GPa and a module of 14.622 GPa
The study devoted to study the mechanical properties of composite materials transformed from polyester resin and fiberglass leads to the following conclusions: a) The use of conventional characterization tests (3-point tension and bending) makes it possible to highlight the influence of the nature of the glass fiber on the breaking properties of a laminate glass/polyester
Summary
The composite materials processing industry has enjoyed rapid and steady growth, supported in particular by the diversity of applications [1,2]. Due to their properties of lightness, rigidity and specific resistance, composite materials are used today in a growing number of applications, in increasingly wide fields, ranging from aerospace research to large sporting goods public [3]. In the field of materials testing, the dependable, reproducible quantitative portrayal of physical properties, mechanical properties, is an issue. The results obtained allow us to choose the type of laminate that is best suited for repairing and manufacturing the hulls of fishing boats
