Through-thickness compressive strength of carbon–phenolic woven composites

Carbon–phenolic woven composites are increasingly employed as the material for the heavy-duty journal bearings. Since the through thickness compressive strength (TTCS) is important for the heavy-duty bearing, in this paper, the effects of lay-up angles and specimen thickness of woven composites on TTCS were investigated for the efficient design of carbon–phenolic woven composite bearings. From the experiments and FEM analysis, it was found that the TTCS of the carbon–phenolic woven composite is much dependent on the stacking sequence rather than composite thickness because different stacking sequence produced much different interlaminar stresses.

Localised blast loading of fibre–metal laminates with a polyamide matrix

This paper presents the results of localised blast tests on fully clamped square fibre–metal laminate panels, manufactured using sheets of 2024-O aluminium alloy, woven glass–fibre reinforced polyamide and a polypropylene adhesive. The fracture properties of the composite–metal interface were determined using the single cantilever beam geometry and the measured interfacial fracture toughness was between values in the literature for thermosetting composites and aluminium/glass fibre polypropylene. Observations from blast experiments performed on panels with different stacking configurations are reported. Diamond and circular back face damage were observed, along with pitting, global displacement and tearing of the front face. Examinations of sectioned panels are presented and multiple debonding, plastic deformation and fibre fracture were identified within the panels.     

The influence of distinct fiber arrangement on the thermo-mechanical behavior of steel fiber-reinforced thermoplastic matrix composites

The effect of different fiber arrangements on mechanical behavior was investigated by using both experimental study and finite elements analyses. In particular, this study examined resultant residual stresses and plastic strains of steel-fiber reinforced thermoplastic composite discs under constant convective air cooling conditions. Three composite discs were manufactured with an identical concentration of woven, circular and radial arrays. The thermal and mechanical properties of the composite discs were measured. The numerical and experimental cooling curves were converged to correctly describe the convective cooling condition of the finite element analyses. After the cooling, the residual stresses and plastic strains in each disc were compared with one another and the results were analyzed. No thermal residual stress or plastic strain was observed for the woven fiber array. Residual stress and plastic strain found in the circular fiber array was twice as high as those in the radial fiber array. It is concluded that the reinforcement fiber array of thermoplastic composites is an effective parameter to describe their thermo-mechanical properties for the formation of thermal residual stresses and plastic deformation.     

Mechanical and three-body abrasive wear behaviour of three-dimensional glass fabric reinforced vinyl ester composite

The mechanical and three-body abrasive wear behaviour of two- and three-dimensional E-glass woven fabric reinforced vinyl ester composites were studied in this article. The mechanical properties were evaluated using universal testing machine as per ASTM D-638. Three-body abrasive wear tests were conducted using rubber wheel abrasion tester (RWAT) under different abrading distances at two loads, wherein the wear volume loss were found to increase and that of specific wear rate decrease. The results indicate that the three-dimensional glass woven fabrics in vinyl ester (G_3D–V) have significant influence on wear under varied abrading distance/loads. Further, it was found that G_3D–V composite exhibited lower wear rate compared to two-dimensional glass woven fabric reinforced vinyl ester (G_2D–V) composite. The worn surface features, as examined through scanning electron microscope (SEM), show ruptured glass fiber in G_2D–V composite compared to G_3D–V composites.
