Interlaminar fracture toughness testing of composite mode I and mode II DCB specimens
Polymer Engineering & Science, 1988AbstractA computer controlled test procedure for evaluating mode I and mode II interlaminar fracture behavior was used in experiments with eight different resin matrix/graphite fiber composites. Four analytical methods for calculating fracture toughness were compared.

Mode I Interlaminar fracture Toughness and Fracture Mechanism of Angle-Ply Carbon/Nylon Laminates
Journal of Composite Materials, 1996Interlaminar fracture toughness and fracture mechanism in carbon fiber reinforced nylon laminates have been investigated. Mode I interlaminar fracture toughness tests are carried out on the double cantilever beam (DCB) specimens made of four kinds of angle-ply laminates. These laminates exhibit unstable "stick-slip" crack propagation.

Experimental Investigation of Mode I Interlaminar Fracture Toughness in T300/914 Composite
Materials Today: Proceedings, 2020Abstract An aerospace structural material T300/914 has been studied to understand the Mode I interlaminar fracture toughness. For experimental analysis a Double Cantilever Beam (DCB) test is conducted on the laminate to estimate the Mode I interlaminar fracture toughness of the sample.

Study on mode I interlaminar fracture toughness of laminated plates considering interface angle
Journal of Reinforced Plastics and Composites, 2022Multidirectional laminates are more widely used in practical engineering, and their fiber bridging characteristics are more obvious than unidirectional laminates. Due to the deficiency of research on the relationship between interface angle and interlaminar fracture toughness of multidirectional laminates, the numerical model of interface mode I ...

Mode I and Mode II interlaminar fracture toughness of CFRP/magnesium alloys hybrid laminates
Composite Interfaces, 2016AbstractThe fiber metal laminates (FML), consisting of carbon fiber reinforced polymer prepregs and magnesium alloys sheets, were introduced, and the Mode I (peel) and Mode II (shear) interlaminar fracture toughness of the FMLs were investigated. The results show that the Mode I interlaminar toughness (0.23 kJ/m2) of the FMLs is much lower than the ...

Prediction of Mode I interlaminar fracture toughness of stitched flax fiber composites
Journal of Materials Science, 2017This paper aims to propose a simulation procedure to predict the interlaminar fracture toughness of stitched flax fiber composites through a virtual double cantilever beam test. The proposed procedure is constituted of two steps. First, the interlaminar failure of unstitched flax fiber laminate, as the parent laminate, is modeled using cohesive ...

Analytical compliance method for Mode I interlaminar fracture toughness testing of composites
Composites, 1987Abstract An analytical compliance method has been successfully applied to Mode I interlaminar fracture toughness tests for laminated composites. A new double cantilever beam (DCB) specimen was designed to measure load-line crack opening displacement with high accuracy, and an interpolation function proposed to calculate the crack length and the ...

American Society for Composites 2017, 2017
Delamination has always been regarded as one of the most critical failures in laminated composites. The growing interest in a more rapid, out-of-autoclave (OOA) manufacturing techniques for automotive applications such as compression moulding and thermoforming has prompted the engineering community to further investigate and understand the delamination

AN ALTERNATIVE METHOD FOR DETERMINING THE MODE I INTERLAMINAR FRACTURE TOUGHNESS
2017A simple test method is proposed to measure the mode I interlaminar fracture toughness of composite.The fracture toughness measured from the present method is consistent well with those determined from the methods recommanded by the ASTM standard.

The toughness contribution of bamboo node to the Mode I interlaminar fracture toughness of bamboo
Wood Science and Technology, 2013Bamboo is a kind of biological composite reinforced by unidirectional long fibers. The cleavage strength along grain of bamboo internode is low; however, the existence of bamboo node can hinder the propagation of interlaminar crack to make up for the defect of weak opening mode fracture toughness along interlamination.
