Influence of The Textile Reinforcement on The Mechanical Behavior of Polymer Composite Materials

Investigating the impact of textile preforms on the mechanical characteristics of composite plates made of glass textile structures and epoxy resin using compression molding technique was the goal of this work. An epoxy resin system served as the matrix, and various woven (plain, twill, basket), nonwoven (mat), and unidirectional (UD) textile structures made from E-glass fibers were employed as reinforcement elements. Compression molding of pre-impregnated semi-finished textile materials (prepregs) was used to create the composites. Fiber pull-out and delamination are the main challenges in the manufacturing of polymer textile composites. As a result, the most crucial aspects of producing polymer textile composites were making ensuring that the textile structures were well-impregnated with resin into the prepreg and that the layers in the composites had a good interface. The generated composites were then subjected to micro/macro examinations using a SEM microscope and DSC thermal analysis. Flexural strength and modulus of elasticity were measured using a three-point flexural method to assess the mechanical behavior of all manufactured textile composites. The performance of polymer textile composite materials is directly influenced by the type of textile structures used as a reinforcing composite constituent, according to the results obtained.
