ジャーナル フリーA calculation method of M-CLT for the friction coefficient of the CFRP composite laminate edge is proposed based on the experimetal friction coefficient of unidirectional lamina with fiber orientation dependency. A high degree algebraic equation for the friction coefficient of the CFRP composite laminate edge is derived by using the Coulomb's friction law and the classical lamination theory. Numerical experiment of a frictional contact problem is performed by means of a nonlinear three-dimensional finite element analysis, and the friction coefficient ofthe CFRP composite laminate edge are obtained for various contact directions andcompared with those obtained from the present calculation method. Good consistency is found between the two kinds of results. Furthermore, a simple calculation example for two beams with frictional contact under uniform pressure is presented to investigate the practical validity of the present method and the effects ofdifferent treatments for the friction coefficient on the contact stresses.抄録全体を表示PDF形式でダウンロード (5960K) -

ジャーナル フリーIn polypropylene resin matrix glass fiber injection molding composite materials, surface of fibers is usually treated by coupling and/or sizing agent and resin is modified by malefic acid because mean fiber length is shorter than their critical length, and interfacial adhesion strength between fibers and resin is low. Therefore, fiber strength has not been utilized completely in these composite materials. In the present study, we propose a method to improve the interfacial adhesion strength by increasing shear strength between fibers and resin, which can be attained by increasing mixing pressure in kneading machine. Since stress-strain relation of composite materials is affected by surface treatment of fibers, interfacial adhesion strength was evaluated by the average interface shear stress through a visco-elastic model. The effect of mixing pressure was discussed based on the shear stress. For a composite material with no surface treatment of fibers and no resin modification, the interfacial shear strength was higher for higher mixing pressure. On the other hand, for a composite material with the surface treatment and the modification, the effect of mixing pressure on the shear strength was not observed. For these materials, however, higher mixing pressure also contributes the adhesion strength between fibers and resin because fiber length in the materials is longer for higher mixing pressure.抄録全体を表示PDF形式でダウンロード (869K) -

ジャーナル フリーThis paper describes the application of Michelson interferometric fiber-optic sensors to monitor the damage in fiber-reinforced plastics under tensile loading. The tested material was an unidirectionally aligned carbon fiber reinforced epoxy composite. A fiber-optic sensor was bonded to the surface of the specimen. A He-Ne laser was used as the light source. Optical interference signal, strain as well as acoustic emission were measured during the tensile test. The behavior of the optical interference signal was compared with both strain and acoustic emission data. Optical interference signals with high amplitude and high frequency were detected when damage occurred. The Michelson Interferometric fiber-optic sensor proved to be effective for monitoring the damage processes of the material studied.抄録全体を表示PDF形式でダウンロード (6062K) -
