Mechanical properties of novel different stitched density 3D hybrid basalt composite
This paper describes the experimental work carried out to understand the mechanical behavior of polymeric composite materials reinforced by 3D hybrid basalt fabrics. The novel reinforcements used consist of two outer layers of a specific woven fabric combined with two inner layers of knitted fabrics. The fabric layers were stitched together with paraaramid threads with different stitched densities. The stitched densities were evaluated by the area of each stitched square, namely, unstitched, lcm2 and 0.25cm2. These reinforcements were impregnated with polyester resin using the RTM technique and the corresponding composites obtained were tested under tensile, bending and impact loads. The results obtained show that the stitched density influenced significantly the mechanical performance of the materials. The composite with lcm2 stitched density presented the best results concerning tensile stress at fracture, flexural strength and energy absorption
