Abstract: Laminated composites are a key area of research due to their cost-effectiveness and productivity.Fiber-reinforced laminated composite structures are widely used for their excellent strength-to-weight ratio.These composites are typically manufactured using the Vacuum Assisted Resin Transfer Molding (VARTM) method.In laminated composites, properties are highly dependent on the orientation of the laminates and their proper adhesion with the epoxy matrix.This study focuses on the application of VARTM in fabricating fiberglass laminated composites using three glass fiber laminates oriented at 0 • , 45 • , and 90 • , impregnated with epoxy resin under vacuum assistance.The features of these composites are compared with those of composite with laminates parallel to one other at 0 • and 45 • .The manufacturing process involved curing the composite sheets for 24 h, followed by cutting tensile specimens according to standard D3039.Results showed that specimens with all laminates oriented at 0 • to the loading direction exhibited the highest strength of 253 MPa, while specimens with laminates oriented at 45 • showed the lowest strength 69 MPa and highest elongation, i.e., strain of 0.22 mm/mm.
