JOURNAL FREE ACCESSThe relation between mechanical properties of reinforcing fibres using PAN based carbon fibres of various tensile strength and modulus of elasticity and those composite materials was studied. The tensile properties were discussed in the previous paper, and in the present paper, the compressive and shear properties ar discussed. The 0°compressive modulus of CFRP is in proportion to tensile modulus of the reinforcing fibre, which is explained well by a rule of mixture. On the 0°compressive strength, carbonized fibre composites showed higher strength than graphitized fibre composites. This is primarily due to the difference between compressive strength of fibre of the carbonized fibres and that of the graphitized fibres. The 0°compressive strength of CFRP for the graphitized fibres depends on the compressive strength of the fibre, and for the carbonized fibres depends on the modulus of the matrix resin. The 90°compressive strength is not affected by the properties of the reinforcing fibres. The shear modulus is not affected by the properties of the reinforcing fibres. The shear strengths under interlaminar and under in-plane shear for the carbonized fibre composites are higher than those for the graphitized fibre composites. This may cause to the difference of bonding strength between the carbonized fibre to matrix resin and the graphitized fibre to the matrix resin.View full abstractDownload PDF (5522K) -

JOURNAL FREE ACCESSInvestigation was made on estimation methods of the fracture toughness value and the fatigue crack propagation behavior by applying J-integral to the plain woven glass cloth FRP. Fracture toughness tests were done by an Instron testing machine. Repeated zero-tension fatigue tests were conducted under the constant stress amplitude with the test frequency 0.5 Hz by a hydraulic fatigue testing machine. As the result of this study, it was shown that the fracture toughness value of plain woven glass cloth FRP could be evaluated to some extent with the aid of the J-integral R-curve. And, the evaluation method of J-integral range (ΔJ) on the fatigue crack propagation behavior was experimentally confirmed by investigating the effects of the initial crack length and the test specimen configurations. Furthermore, the test results showed that the fatigue crack propagation curvecould be arranged by measuring the compliance changes of load-COD curves during the fatigue test.View full abstractDownload PDF (6883K) -
