Production and characterization of basalt fiber/pet composites

The use of fiber-reinforced thermoplastic composite materials is increasing day by day due to their high strength and recyclability. In addition to these superior advantages, high melt viscosity is among the disadvantages of these materials because it makes reinforcement absorption difficult. This problem can be solved by using hybrid yarns in which reinforcement and thermoplastic fibers are homogeneously mixed for the production of thermoplastic composites. This study, it was aimed to prepare basalt fiber/PET hybrid yarns containing basalt fiber in different volume ratios by air-jet mixing method and to prepare thermoplastic composite materials by pressing from fabrics woven from hybrid yarns. By determining the mechanical properties of basalt fiber/PET thermoplastic composites prepared to contain basalt fiber in different proportions by volume, the effects of basalt fiber amount in hybrid yarn blends on the mechanical properties of the composite material were examined and the most appropriate basalt fiber amount was determined.
