Abstract
Two kinds of warp-knitted spacer fabrics are knitted on a Raschel latch needle warp knitting machine with glass continuous-filament yarns. The glass/ unsaturated polyester resin composites are produced by manual molding technology. The tensile and flexural properties of composite specimens are tested in automatic testing machine. The tensile and flexural properties of composites are analyzed in the course, wale and diagonal directions. The results show that mechanical properties of composites possess obvious orthotropic characteristics; the differences of fiber volume fraction and yarn orientations result in the different tensile mechanical of composites. Warp-knitted spacer fabric composites revealed good flexural mechanical properties.
