Carbon Fibre Composite

Carbon Fibre coordination compoundStrength of Laminated muscular Composites LabSummaryThis report comp ars the results of theoretical weighings undertaken to predict the tensile expertness of ampere-second fibre reinforced composites against experimental results. Two main methods for the calculation of tensile strength argon used the rule of mixtures and the ten part rule. These standard theories appear to be valid for the majority of cases although inconsistencies are observe for the 90, transversely rouseed, isostress condition.AimsTo become familiar with composite materials, their structure and selectTo understand how carbon fibre reinforced polymer, CFRP, materials are tensile time-testedObjectivesTo examine samples of composites and their precursorsExamine typical microstructureTensile test different samples of CFRP composites instaurationThis work looks at the tensile strength of different structural make-ups of carbon fibre reinforced polymers. Carbon fibres have gre atest strength when they are loaded in the isostrain (0) condition as illustrated in human body 4.1. In the isostrain condition, the majority of the applied load is transferred to the long fibre strands whereas in the isostress condition, the load is acting perpendicular to the fibre length and yields a far reduce maximum strength. When there are multiple layers of fibres in the composite, orientated in different directions, otherwise known as a mixed hunt lay-up, the maximum tensile strength varies with respect to the fibre angle.Figure 4.1 Composite LoadingFour different composite lay-up structures are looked at in this report. Each lay-up consists of a total of 16 layers which are symmetrical about the neutral axis. The layups of the composites areWhere subscripts2, 4, 8 = multiple of layers historied in the bracketsS= refers to symmetry about the neutral axisA 0 8SB 90 8SC +45,-45 4S D 0/+45/-45/902SThe test specimens consist of a separate of CFRP with metal plates c ommitted with epoxy resin at either end as shown afterwards on in Figure 5.1. These metal plates are purely for clamping of the CFFP section into the in the tensile testing rig as shown in Figure 5.2.Experimental MethodThe dimensions of the test specimens are noted for each slash prior to any testing and will be used for unclouded comparison in the theoretical calculation methods. Dimensions for each specimen, A-D are shown at a lower place where x and y relate to the dimensions shown in Figure 5.1.
