Structural integrity assessment of tufted textile composite and its comparison with laminated textile composite
AbstractThree dimensional composites have been used in aerospace industry to improve interlaminar strength. This paper evaluates the 3D tufted composites from aspect of their mechanical properties. The tufted composite panel was manufactured based on polyester resin as well as an untufted laminated composite for comparison purposes. Experiments show that specimens with transverse tufting suffer slighter reduction in the tensile strength than longitudinal tufting. The tufted composites are found lower tensile strength compared with laminated composite samples accompanied with slight improvement in the compression strength and high strain rate tensile strength. The experimental results presented in this paper should be valuable to achieve desired property of tufted composites for specific aerospace applications.
