Alternative test method for interlaminar fracture toughness of composites

International Journal of Fracture, 2007
Two methods of determining the mode I interlaminar fracture toughness for fiber-reinforced polymer matrix (FRPM) composites using a double cantilever beam (DCB) test are compared. The standard method of determining GIC is based in linear-elastic fracture mechanics theory and requires a visual measurement of the crack length, presenting data acquisition

Mixed Experimental‐Structural Model for Interlaminar Shear Fracture Toughness

Journal of Aerospace Engineering, 1991
For brittle composite materials, a mixed experimental and structural model is developed to determine a consistent interlaminar shear fracture toughness (GIIc) in an end notched flexure (ENF) test. The ENF procedure presented here differs from the customary ENF test in that one specimen is used for multiple measurements of compliances and the ...

Interlaminar fracture toughness of graphite fiber-reinforced polyimide composites

Mechanics of Composite Materials, 1995
The present study has proved the effectiveness of the application of viscoelastic polymers with increased fracture toughness to graphite/polyimide composites interlaminar fracture toughness improvement. Thermoplastic polysulphone film and thermoresistant structural adhesive have proved to be inherently more effective for composites' delamination ...

Interlaminar fracture toughness of woven E-glass fabric composites

Journal of Composite Materials, 2011
Composite materials fabricated using woven fabrics are characterized for fracture toughness. Crack propagation behavior in woven fabric composites is investigated with respect to the periodic pattern produced as a result of the weave structure. Additionally, experimental methods for determining fracture toughness are investigated for woven fabric ...

On the Interlaminar Fracture Toughness of Some Softwood Cores

Journal of Reinforced Plastics and Composites, 2008
The interlaminar fracture toughnesses of balsa and end-grain balsa cores with glass-reinforced plastics (GRP) face elements widely used as constructive members, has been investigated experimentally in this study. The interfacial fracture toughness is determined using a mode-I cracked sandwich beam (CSB) test.

Investigations of interlaminar fracture toughness of laminated polymeric composites

Mechanics of Composite Materials, 1998
The behavior of interlaminar fracture of fiber reinforced laminated polymeric composites has been investigated in modes I, II, and different mixed mode I/II ratios. The experimental investigations were carried out by using conventional beam specimens and the compound version of the CTS (compact tension shear) specimen. In this study, a compound version

Interlaminar Fracture Toughness of a Graphite/Epoxy Multidirectional Composite1

Journal of Engineering Materials and Technology, 2000
In this paper, an experimental investigation on interlaminar fracture behavior and fracture toughness of a graphite/epoxy multidirectional composite laminate is presented using end-notched flexure specimens. The 0/θ interfaces are considered. The interlaminar fracture toughness is obtained and compared using three data reduction methods, i.e., the area

Interlaminar Fracture Toughness of Glass Fibre-Reinforced Polypropylene Laminates

Polymers and Polymer Composites, 1999
A complete set of experiments was carried out to investigate the fracture behaviour of continuous glass fibre-reinforced polypropylene composites and the corresponding polypropylene resin. Mode I and mode II interlaminar critical strain energy release rates are reported for this material for the first time.
