Abstract The mechanical performance of woven composites was analyzed focusing on their nonlinear and rate dependent asymmetric/anisotropic deformation behavior. Three key characteristics were identified which are indispensable for realistically simulating the mechanical performance of woven composites: the asymmetric material behavior between tension and compression, its anisotropic and nonlinear evolution and rate dependency. To include all three characteristics into the nonlinear finite elemen...

Abstract This paper deals with the effect of temperature (room and low temperatures) on the tensile properties at high strain rates of CFRP laminates. Dynamic tests were performed on different carbon/epoxy laminates configurations: unidirectional, [0] 10 and [90] 10 , and quasi-isotropic [±45/0/90] S . All these tests were carried out at two temperatures: 20 and −60 °C. Validation of Hopkinson bar theory using one-dimensional wave propagation theory was performed by analysing the effect of low t...

This paper is a detailed review of the strain rate dependence of some mechanical properties of polymer composite materials. An attempt is made to present and summarize much of the published work relating to the effect of strain rate studies done in the past on the tensile, shear, compressive, and flexural properties of composite materials to better understand the strain rate effects on these mechanical properties of fiber-reinforced polymer composite materials. © 2004 Wiley Periodicals, Inc.

Abstract Two dimensional generalised plane strain finite element models have been developed to simulate some of the different local fabric geometries which influence the damage development seen in woven fabric laminates as a function of number of reinforcing layers. It is shown that the stiffness is relatively insensitive to such geometric variations, but that the strain energy release rate associated with crack formation is influenced significantly by the crack location. In particular, where th...

Abstract The choice of composite materials as a substitute for metallic materials in technological applications is becoming more pronounced especially due to the great weight savings these materials offer. In many of these practical situations, the structures are prone to high impact loads. Material and structural response vary significantly under impact loading conditions as compared to quasi-static loading. The strain rate sensitivity of both carbon fibre reinforced polymer (CFRP) and glass fi...

Thick-section composites made from plain-weave S-2 glass fabric (24 oz./sq. yard) and vinyl ester (411-C50) resin have been tested over a wide range of strain-rates (200-1600 s -1) using a compression split Hopkinson pressure bar (SHPB) with a momentum trapping device. Experiments were performed in two material directions: thickness and fill. Three different types of specimens having rectangular cross sections were tested with thickness ranging from 3.8 mm to 12.7 mm. The strain-rate effects on ...

Abstract This paper presents results from mechanical tests on glass fibre-reinforced polypropylene laminates. Materials were manufactured in a press and the average rate of cooling from the forming temperature after pressing was varied from 0.23 to 55°C min −1 . The cooling rate was found to affect the matrix structure and to strongly influence fracture behaviour. Faster cooling resulted in improved Mode I and Mode II fracture energies, and smaller delaminated areas after impact. Results are com...

The present work aims at preparing glass-fiber reinforced epoxy resin composite modified with reactive end-capped carboxylic imide oligomer. The carboxylic imide 2,2-bis[4-(4-aminophenoxy)phenyl propane (CIBAPP) oligomer was synthesized via two-step polycondensation of 2,2-bis[4-(4-aminophenoxy)phenyl propane (BAPP) diamine and trimellitic anhydride (TMA), then the oligomer was characterized by FTIR spectrum and solubility test. The oligomer was used as a blending component for the modification ...

This article covers an in plane experimental characterisation of a polypropylene glass fibre reinforced woven composite. Tensile, shear and compression loadings were carried out with a standard tensile rig and a crossbow/Hopkinson pressure bar rig. The specimen strain was measured by digital image correlation technique. It is concluded that the composite stiffness and strength are highly sensitive to strain rate. Static and dynamic multicycle tests were also undertaken to identify and quantify s...
