Abstract
Abstract Aeronautic structures are exposed to a great variety of temperatures and humid environments during service. Nowadays, it is known that the combined influence of moisture and temperature induces further detrimental effects on the fatigue behavior of bonded joints when compared to the influence of each isolated condition. The effect of hygrothermal pre-conditioning on the fatigue delamination growth onset of different bonded technologies was investigated. This paper provides a material database for composite-joints tested under different environments and gives important insights on the failure mechanisms observed under cyclic loadings. This information can be latter used to validate analytical and numerical models.

In this work, the thermal stability, the non-isothermal cure kinetics and distributed reactivity model (DRM) for fiber reinforced resin matrix composite (T800H/3900-2 prepreg) have been systematically analyzed using combined phenomenological and partially fundamental approaches. It has been shown that the proposed actual kinetic model (expressed through the three-parameter Sestak-Berggren (SB) model including the diffusion effects) more accurately describes the curing process than the idealized ...

Abstract The influence of the temperature on pure modes I and II fracture behavior of carbon–epoxy composite bonded joints was investigated. The joints were exposed to a specific range of temperatures during three months in order to simulate long exposure time. Three temperatures were studied: 0 °C, 25 °C (room condition) and 50 °C. The limit temperatures were defined in order to be representative of the extreme climatic conditions to which structures can be exposed in winter and summer in Portu...

Abstract This work introduces a procedure based on the real time monitoring of the specimen’s compliance for the experimental characterization of the fatigue behaviour of interlaminar cracks in composites. The methodology was applied to a mode II loading in a three-point end notch flexure test. The onset point for fatigue damage was determined with a precision of one cycle by establishing a threshold on the compliance variation from its initial value. On the other hand, the crack growth rate cur...

Abstract This paper addresses the effect of temperature on the mixed-mode interlaminar fracture toughness and fatigue delamination growth rate of a carbon-fibre/epoxy material, namely IM7/8552. Quasi-static and fatigue characterisation tests were carried out at −50 °C, 20 °C, 50 °C and 80 °C, using asymmetric cut-ply coupons. The experimental results show that temperature may have an accelerating or delaying effect on delamination growth, depending on the loading regime, i.e. either quasi-static...

In this paper, fatigue life estimation for delamination growth of laminated fibre reinforced polymer (FRP) composite structures in mode I and mode II based on fracture mechanics is presented. The proposed method was applied to delamination of glass/epoxy laminated composite. Both the threshold energy release rate (Gth) and the delamination propagation based on Paris’ law were studied. The double cantilever beam (DCB) specimen for mode I and 3 points End-Notched Flexure (3ENF) specimen for mode I...

Abstract This paper analyzes delamination processes under modes I and II fracture and fatigue loading for two types of composite materials. The studied materials were manufactured with the same unidirectional carbon reinforcement though with two types of epoxy matrix. Experimental data were treated with a probabilistic model based on a Weibull distribution allowing the identification of relevant aspects of the fatigue behavior of the materials, such as the estimation of the fatigue strength for ...

Abstract Structural adhesives are being widely adopted in aerospace and automobile industries. However, in many cases, hostile environments cause non-ignorable degradation in joints mechanical performance. In this work, a combined experimental–numerical approach was developed to characterise the effect of cyclic-temperature environment on adhesively bonded joints. The environmental degradation factor, Deg, was introduced into a cohesive zone model to evaluate the degradation process in the adhes...

Abstract The scope of the present work is to investigate the possible effects of manufacturing and in-service induced reduction of bonding quality on the mechanical performance of composite bonded joints appearing in aeronautical applications, due to defects that cannot be detected sufficiently by means of conventional NDT. To this end, an experimental program has been conducted to measure mode-I interlaminar fracture toughness of adhesively bonded CFRP laminates. Five different representative s...

Abstract In this paper, interlaminar crack initiation and propagation under mode-I with static and fatigue loading of a composite material are experimentally assessed for different test temperatures. The material under study is made of a 3501-6 epoxy matrix reinforced with AS4 unidirectional carbon fibres, with a symmetric laminate configuration [0°] 16/S . In the experimental programme, DCB specimens were tested under static and fatigue loading. Based on the results obtained from static tests, ...

Abstract In this paper, the effect of hygrothermal conditions on elastic properties of polymeric composite materials is investigated by the finite element method. A micromechanical degradation model is developed based on Fick’s second law utilizing an ABAQUS python scripting micro modeling (APSMM) and an ABAQUS parallel finite element analysis (APFEA). The APSMM algorithm is used to study the degradation of elastic constants of a fiber-reinforced polymeric composite (AS/3501-5) under specific hy...

This paper aims to propose a temperature-dependent cohesive model to predict the delamination of dissimilar metal–composite material hybrid under Mode-I and Mode-II delamination. Commercial nonlinear finite element (FE) code LS-DYNA was used to simulate the material and cohesive model of hybrid aluminium–glass fibre-reinforced polymer (GFRP) laminate. For an accurate representation of the Mode-I and Mode-II delamination between aluminium and GFRP laminates, cohesive zone modelling with bilinear ...
