“…The axial tensile tests were conducted on nothed and unnotched specimens at RT, 95 o C and 125 o C, the results are shown in Figure 5. For the unnotched specimens, the stress-strain curve is almost linear at RT, which is similar with CF/PPS [13] and GF/epoxy [9], indicating that the polymer chains are frozen and the matrix is brittle at this temperature.…”

“…For the unnotched specimens, the specimens at RT failed in a brittle mode, which are characterized by fibre bundles fracture and little amount of delamination at the surface ply where a higher interlaminar stress usually presents [9]. Judging from the extent and degree of damage, the initial damage is generated from the free edge.…”

“…Then the failure behavior of the notched specimen will be dominated by the damage around the hole due to the stress concentration. Reference [9][10][11] investigated the notched tensile behavior and gave a deep insight into damage progression in the vicinity of the hole. They observed that the inital damage generated from the edge of the hole, leading to a redistribution of stress.…”

Abstract. The effect of temperature on the mechanical behavior of 8-H satin woven glass fabric/polyethylene sulfide (GF/PPS) was investigated in this paper. Static-tensile tests were both conducted on notched and unnotched specimens at typical temperatures (ambient, 95 o C and 125 o C) based on the glass transition temperatures (Tg) of the neat resin and composite, their strength and moduli were obtained and compared. The damage patterns of failed specimens of notched and unnotched were examined with the aid of high-definition camera and stereomicroscope. The results of stress-strain relationships showed that the slight nonlinearity of the curves were observed for these two specimens, which was associated with the plastic deformation of localized resin. The damage patterns of notched and unnotched specimens at different temperatures proved that damage and plastic deformation were two simultaneous mechanisms and it was prominent in the notched. It was the overstress accommodation mechanism that led to a relative high strength rentention for the notched and a reduction of the hole sensitivity. The results obtained in this paper indicated that GF/PPS can be used as secondary aircraft structures at elevated temperatures higher than its Tg.

“…The homogenised properties of the composite were found to show good agreement with the experimentally measured properties of [18]. A parametric study, in which the size of the generated microstructure was varied, was carried out and it was found that the elastic moduli converged for a microstructure window which has a side of length of approximately 20 times the fibre radius, which for this material is approximately half a ply thickness (i.e.…”

General rightsThis document is made available in accordance with publisher policies. Please cite only the published version using the reference above. Abstract A computational constitutive model is presented to predict matrix cracking evolution in laminates under in-plane loading. Transverse cracks are treated as separate discontinuities in the micro model which provides damage parameters for the macro model. Both micro and macro models are implemented using Finite Element Analysis (FEA); specifically ANSYS, avoiding limitation of analytical micro modeling. The computational cost of the micro model is limited to constructing a database (DB) of micro-model predictions a priori. The macromodel is simply a FEA discretization of the structure using plane stress or shell elements in ANSYS. The macro model queries the DB, which effectively becomes a constitutive model. The damage surfaces in the DB are obtained from the results of large number of finite element micro-scale (unit-cell) analyses. The proposed procedure is implemented in ANSYS as a usermaterial subroutine for transverse crack initiation and propagation in symmetric cross-ply and [0r/(s/0n]s laminates under in-plane loads. This method is also examined to study matrix crack evolution in tensile specimen with open hole and the results found to be in good agreement with available experimental data.
