This work aims to compare tensile properties between different glass fiber architecture reinforced polyester composites which are fabricated by the hand lay-up technique. The stacking sequences of glass fibers consists of five layers which are plain woven (PWGC), short strand fiber (STGC), and sandwich layer glass composites (SLGC) (two layers of plain woven as skin layers and three layers of short glass fibers as a core). The results showed that the tensile strength of all different composite laminates are significantly higher compared to the neat resin and plain woven glass reinforced polyester composites showed the highest values compared with other composite laminates. The tensile failure in PWGC laminate is governed by extensive fiber pull out and delamination, whereas in STGC laminates the failure shows pull out of fibers and little delamination. On the other hand, SLGC hybrid laminate shows mixed failure mode where extensive fiber pull out with little delamination is observed in plain woven skin layers and little fiber pull out in short glass fibers in the core of the laminate.
