Composite materials consist of combining two and more ingredients. Thermoplastic composite materials are prevalently used in various industrial applications due to their functional properties. The combination of continuous (woven or unidirectional/non-woven) fiber and resin layers is defined as composite in laminate form. Glass fiber is one of the promising and competitive materials in the manufacture of composite laminates. Fiber content is important because it affects the mechanical properties of composite materials. In this study, the tensile, compressive and impact properties of thermoplastic composite laminates with different fiber configurations were investigated experimentally. So that the effective use of materials in engineering applications, it is essential to know these mechanical properties related to the loads they are exposed to. The reinforcing element of composite materials, whose matrix element is polypropylene, is chopped-woven glass fiber with four configurations. Specimens were cut of sizes conformity to standard via water jet. Mechanical tests of specimens prepared in longitudinal and transverse directions were carried out at room temperature. Stress-strain curves of the materials were created, elastic modulus values were calculated, tensile, compressive and impact strengths were determined and compared on the graphs. The mechanical properties of the composites varied depending on the weaving direction and fiber ratio. The strength and elongation of the composite laminate having higher woven fiber ratio and layer have been greatest.
