ジャーナル フリーBecause of extremely large anisotropy of unidirectional carbon-fiber reinforced plastics, it is very difficult to obtain its ultimate tensile strength in the fiber direction by use of the usual specimen shapes which have been used. Accordingly, (1) the stress distributions in the orthotropic specimens with circular cutouts widthwise or thicknesswise were analysed by use of finite element method in order to discuss which shape was more feasible, (2) as the result of static and fatigue tensile tests with various kinds of specimen dimensions, it was found that the fracture behaviors reasonably coincided with the theoretical consideration, and (3) consequently, a specimen that has larger circular radius of curvature cut out in the thickness, larger reduction ratio from ends to central crosssections and longer ductile tabs attached to both fixing ends and other related procedures were proposed for a standard testing method of unidirectional carbon-fiber reinforced plastics.抄録全体を表示PDF形式でダウンロード (1713K) -

ジャーナル フリーIn this paper, a method to estimate the mechanical properties of GFRP, in which the fibers are dispersed randomly in the matrix, is proposed by applying the probabilistic technique. The analytical model used in this method is composed of n-layered elements, that are the unidirectionally reinforced mats. The principal axes of these elements are located in the composed model by using the random vectors. To examine the above mentioned technique, the estimations of Young's modulus, Poisson's ratio and tensile strength of the chopped strand mat GFRP are performed. The analytical result fairly coincides with the experimental one.抄録全体を表示PDF形式でダウンロード (628K) -

ジャーナル フリーThis report is on the result of flexural fatigue test of honeycomb sandwich structure made of NOMEX honeycomb core, glass fabric, KEVLAR-49 fabric and graphite fiber reinforced plastic facing. The flexural fatigue property was obtained by using the fatigue testing machine of constant load type UF-500, and electro hydraulic testing machine SERVOPET Lab-5. The flexural fatigue of the 1/4 NOMEX core sandwich structure is higher than that of 1/8 NOMEX core sandwich structure. We found that the honeycomb sandwich structure with the facing of graphite reinforced plastics can be used as structure components.抄録全体を表示PDF形式でダウンロード (5001K) -

ジャーナル フリーThe influence of test variables in fracture toughness test of glassfiber reinforced polycarbonate is studied by using DCB testpiece. The fracture toughness which shows the degree of difficulty of initial crack propagation, represents a constant value with a longer crack than a given length. The fracture toughness slightly increases with the increase of the tensile speed within the range of a Instron type testing machine and decreases with increase of the plate thickness. Moreover, the fracture toughness seems to be effected not by the plate width but by the restraint of rotation in the chucking systems.抄録全体を表示PDF形式でダウンロード (310K) -
