Fracture characteristics and anisotropy in notched glass fiber reinforced plastics

Abstract

The damage mechanism of reinforced plastics may be present in many different ways, since it depends on many factors. Highlights may be given to the effect of stress concentration in of geometric discontinuity in the sections of these structural elements, which in general always leads to certain characteristics of the fracture. In the case of glass fiber reinforced plastics (GFRP) it is expected the same tendency, beyond the influence of reinforcement and its internal orientation in the layers (anisotropy). The aims of this work are detailed study of the influence of the holes (longituninal section) in the characteristic fracture in GFRP submitted to tensile loading. Three different configurations of composite laminates were studied: two reinforced with Eglassfiber bidirectional textil fabric and the other only with short mats, also Eglassfiber. The results showed the influence of all parameters listed above in the final fracture characteristics and residual properties.

Crushing performance of pultruded GFRP angle section with various connections and joints on lattice towers

“…Glass fiber reinforced polymer (GFRP) possesses significant characteristics such as being light weight, corrosion resistant, non-conductive, environmentally friendly, high tensile strength, low moisture absorption capacity and good life cycle [1,[4][5][6][7][8]. As such these materials are very much used in aerospace, military, shipping, car, construction industries, sports and recreation, marine, and energy sectors [9,10].…”

Mechanical behavior and dynamic damage constitutive model of glass fiber-reinforced Vinyl Ester with different fiber contents

“…During the application process, materials/components are inevitably affected by static and dynamic loads and high and low temperature environments, 4 Given the inhomogeneity of the GFRP structure, it has anisotropy and low interlaminar shear modulus in mechanical properties. 6 , 7 Research on mechanical properties of GFRP still needs to be developed due to many influencing factors.…”

Mechanical Properties of Glass Fiber Reinforced Polymers Members for Structural Applications

“…Wu & Bai 36 investigated the web crippling behavior of GFRP sections and Wu et al 37 conducted a comparative study on static and fatigue performances of pultruded GFRP joints using ordinary and blind bolts. Recently, Tinô et al 38 assessed the influence of holes (longitudinal section) in the characteristic fracture in GFRP. Kumar et al 39 described fractographic features observed in aerospace composites failed under tensile loads.…”
