Experimental Investigation of Glass Fibre Reinforced Polymer Laminates. Characterization of Materials

      Аннотация: To know the mechanical properties of GFRP laminates. Using hand lay-up and press moulding fabrication techniques, the testing samples are prepared as per ASTM-D882, ASTM- D790, ASTM-D785 standard by varying orientation. These specimens are tested under tensile test, flexural test (three-point bend test) and hardness test. The results are compared within three different aligned orientations (0°, 135°, 90°) for fabricated composite. GFRP laminates have wide spread application because of their several advantages like high wear resistance, high strength-to-weight ratio. The results of tensile strength, percentage of elongation, flexural strength, flexural modulus and hardness of the composite were compared. However, the highest values respectively suggesting fibre orientation for effective and maximum stress transfer in laminated composites. The unknown properties obtained by these laminates are used in ABAQUS and HYPERMESH for analysis. MATLAB used for prediction of the unknown values of unknown orientations. The results are compared to obtain the better of the orientations suitable for the composite to manufacture any components.
