“…Styrene emission agent BKY 740, purchased from Alton Chemie, Germany, was utilized to avoid the styrene evaporation from the hybrid resin during the polymerization reaction. composite laminates in which a delamination propagates between the plies all along the fiber direction appropriate to the coplanar assumption in fracture analysis [3][4][5][6]. The formulized resin blend was comprised of 25 wt.% of styrene free polyester and 75 wt.% of vinyl ester.…”

“…These composites have generally good fiber dominated in-plane properties capable of meeting the design requirements for various types of structural applications. However, Z-axis (through the thickness) properties of the composites, such as delamination resistance, have often been far below the expectations due to inadequate performance of the matrix dominated interlaminar region [1][2][3][4][5][6]. Therefore, in some special applications, these materials may exhibit lower overall structural integrity in accordance with their presumed properties.…”

“…It may even occur during processing of the laminates due to contamination or regions of high void content of prepreg that leads to poor ply adhesion locally [3][4][5][6][7]. In general, delamination corresponds to a crack-like discontinuity between the plies and it may typically extend during application of mechanical or thermal loads or both during service life of composites [4][5][6]. Fracture toughness of polymer matrix and interfacial shear strength between the matrix and the fiber are of prime importance in monitoring through the thickness properties of the composites.…”

a b s t r a c tIn this study, mode I and mode II interlaminar fracture toughness, and interlaminar shear strength of E-glass non-crimp fabric/carbon nanotube modified polymer matrix composites were investigated. The matrix resin containing 0.1 wt.% of amino functionalized multi walled carbon nanotubes were prepared, utilizing the 3-roll milling technique. Composite laminates were manufactured via vacuum assisted resin transfer molding process. Carbon nanotube modified laminates were found to exhibit 8% and 11% higher mode II interlaminar fracture toughness and interlaminar shear strength values, respectively, as compared to the base laminates. However, no significant improvement was observed for mode I interlaminar fracture toughness values. Furthermore, Optical microscopy and scanning electron microscopy were utilized to monitor the distribution of carbon nanotubes within the composite microstructure and to examine the fracture surfaces of the failed specimens, respectively.

A new approach is proposed for measuring the J integral (and thus the fracture resistance) of interface cracks in multiply laminates. With this approach the J integral is found from beam curvatures and applied moments. Knowledge of ply layup and stiffness is not required. In order to test the accuracy of the proposed approach, double cantilever beam specimen loaded with uneven bending moments (DCB-UBM) specimens were tested and analysed using the curvature approach and a method based on laminate beam theory. Beam curvatures were determined using a configuration of strain gauges. Good agreement was obtained between the two approaches.
