Mode I Interlaminar Fracture Toughness of Natural Fiber Stitched Flax/Epoxy Composite Laminates – Experimental and Numerical Analysis
The mode I interlaminar fracture toughness of stitched and unstitched composite laminates of continuous UD flax fiber and epoxy matrix was experimentally and numerically investigated. A twistless flax fiber yarn was used for stitching purpose. The mode I interlaminar energy release rate of the unstitched and stitched laminates was experimentally determined through Double Cantilever Beam (DCB) t...
متن کاملEffects of Temperature and Fiber Orientation on the Mode I Interlaminar Fracture Toughness of Carbon/epoxy Composites
Delamination is a predominant failure mechanism in composite structures. In the present study, double cantilever beam tests were performed to investigate the effects of temperature and fiber orientation on the Mode I interlaminar fracture toughness, G I , of carbon fiber-reinforced epoxy composites, T800H/#3631. The values of G I for three kinds of laminates, [0 12 //0 12 ], [22.5/-22.5/0 8 /-2...
متن کاملMode I Interlaminar Fracture Toughness of Unidirectional Fiber-Reinforced Polymer Matrix Composites
1.1 This test method describes the determination of the opening Mode I interlaminar fracture toughness, GIc, of continuous fiber-reinforced composite materials using the double cantilever beam (DCB) specimen (Fig. 1). 1.2 This test method is limited to use with composites consisting of unidirectional carbon fiber and glass fiber tape laminates with brittle and tough single-phase polymer matrice...
متن کاملMixed-mode I/II Interlaminar Fracture of CF/PEI Composite Material
Failures in composite materials occur mainly due to interlaminar fracture, also called delamination, between laminates. This indicates that characterizing interlaminar fracture toughness is the most effective factor in the fracture of composite materials. This study reports investigation on mixed-mode interlaminar fracture behaviour in woven carbon fibre/polyetherimide (CF/PEI) thermoplastic co...
متن کاملEffect of Rock Fracture Filling on Mode I and II Fracture Toughness
This paper focuses on some fracture toughness tests performed on the pre-cracked Brazilian specimens of rock-like materials. Also the effect of rock fracture filling on the fracture toughness was considered experimentally. Fracture toughness is a key parameter for studying the crack propagation and fragmentation processes in rock structures. Fracture mechanics is an applicable tool to improve ...
