ジャーナル フリーLinear elastic fracture mechanics is applied to estimation of interlaminar fracture toughness of carbon fiber reinforced composite laminates. Energy release rate approach to double cantilever beam (DCB) specimen is investigated analytically and experimentally. Configurations of specimen and loading system are considered and a new DCB specimen is proposed. Deformation and energy release rate of the DCB specimen is analyzed numerically by using finite element method, and polynomial expressions of compliance and energy release rate, as the functions of crack length, are obtained. Compliance method based on the analysis is successfully applied to mode I interlaminar fracture toughness test. Unidirectionally reinforced carbon/epoxy laminates used for the test. Initial interlaminar crack is introduced mechanically and effect of crack width is examined. The applicability of analytical equations of compliance is examined experimentally. Agreement of the analytical and the experimental results are excellent. The critical energy release rate in mode I crack propagation is measured automatically by using the compliance method. The results are compared with those of the conventional method. The accuracy is improved remarkably.抄録全体を表示PDF形式でダウンロード (4743K) -

ジャーナル フリーNondestructive testing method for fiber orientation and fiber content in fiber reinforced composites, such as CFRP and GFRP, is examined by using 4 GHz microwave. Fiber direction, misorientation, and fiber content are detectable for unidirectional CFRP. In this apparatus, transmitted wave is divided into two cross components and their difference and/or ratio is measured, so that the sensitivity of detecting the fiber orientation is improved and change of the fiber direction is detected separately from that of the fiber content. The sensitivity of the detection is especially good for the fiber direction and misorientation in such thin CFRP samples as less than about 1 mm in thickness. This method, therefore, is found to be preferably useful to check fiber orientation of intermediary materials such as prepreg rather than end constructions or products. The sensitivity of detection for GFRP is rather low in comparison with CFRP, because the difference of electrical property between matrix resin and glass fiber is small. Theoretical formulations and calculations for transmission and reflection of electromagnetic wave in anisotropic layered material are performed, and good agreement with the experimental results is obtained.抄録全体を表示PDF形式でダウンロード (10639K) -
