Carbon Fabric-Reinforced Polymeric Composites Produced by Hand Lay-Up and Investigation of the Tensile Behavior

Abstract

Composite materials are recognized as advanced materials, which can be formed by combining different constituents, excellent mechanical properties can be achieved by chosen appropriate elements and processing. This paper describes that Carbon Fabric Reinforced Epoxy Composites (CFRPs) are produced using twill weave carbon fibers with CR-80 epoxy resin through hand lay-up method. The composite laminates are designed with 10th layers of stacking [0/0/0/0/0]s in with 3.0 mm thickness. Tensile tests are carried out at longitudinal orientation and transverse orientation of the samples in addition to analytical analysis models. A comparison is made between the experimental results of tensile tests data and evaluated statistical point of view. Experimental results indicated that average tensile strength of the composites was obtained around 427 MPa for the longitudinal orientation [0o], while for transverse orientation [90o] sample, average tensile strength was 359 MPa, which is lower than that of the sample. Further, it was concluded that analytical analysis is a good agreement with experimental data.
