“…Here, they improve the mechanical stability of the interfaces of glass fibres, inorganic fibres, or natural fibres, and minerals with a polymer matrix [1]. Moreover, they allow the design of tailored interfacial phases which in turn can control the properties of composite materials [2,3,4]. Silanes also protect fibre surfaces against uptake of water and prevent their swelling which may destroy the finished composite by expansion and delamination.…”

X-ray photoelectron spectroscopy for detection of the different Si–O bonding states of silicon

et al. 2003

X-ray photoelectron spectroscopy (XPS) was used to detect the bonding between a silica particle surface and attached silanes. In addition to the commonly recorded Si 2p spectrum, the Si 1 s level is also accessible when monochromatic Ag Lalpha X-rays are applied. Furthermore, the spectrum of the Si 1 s level shows a fine structure. After spectrum deconvolution, we assigned the fitted spectral peaks to Si-C bonds of the silanes and to the Si-O bonds of the silica network. The recorded Si 1 s spectra were deconvoluted into peaks originating from Si-C bonds and the Si-O-Si silica network. To check the results of spectrum deconvolution, several differently functionalized silanes containing stoichiometric amounts of heteroatoms were applied for silica surface modification. We conclude that spectra deconvolution of the Si 1 s signal is an appropriate means for quantification of surface attached silane molecules.

“…51 , 53 Unlike glass and carbon fibres, poor adhesion of aramid fibres with epoxy resin has been reported in earlier studies. 59–61 Fibre–matrix debonding, fibre breakage, and matrix microcracks were observed on the fracture surface of the [AC] s laminate at quasi–static strain rate (Figure 8(a)). On the other hand, the dominant failure mechanisms of the [AC] s laminate at intermediate strain rate were fibre–matrix debonding and fibre breakage (Figure 8(b)).…”

This study presents the results of an investigation on the tensile behaviour of hybrid polymer composites under different strain rates. Glass/carbon, aramid/carbon, glass/aramid, and glass/aramid/carbon hybrid laminates were produced using vacuum assisted resin transfer molding method with epoxy resin system. Uniaxial tensile testing was performed to determine the tensile strength, modulus and failure strain of the hybrid laminates under quasi static (0.001 s‒1) and intermediate (5 and 10 s‒1) strain rates. Tensile strength and elastic modulus of hybrid composites increased with increasing the strain rate. Hybrid laminates with glass fibre were more sensitive to the strain rate. Carbon layers located at the centre of the hybrid laminates resulted in increased tensile strength, indicating the major role of stacking sequence on the behaviour of hybrid composites. Scanning electron microscope (SEM) was used to examine the fracture surfaces of the laminates. The extent of damage propagation was significantly broader at intermediate strain rates.

“…As the debond length increases, the term D O Hgets smaller and the long-fibre limit becomes increasingly less accurate. From (18), it is apparent that the long-fibre limit requires: A common specimen geometry in single-fibre pull out tests is to place a large, hemispherical droplet on a surface and embed the fibre into the top of the hemisphere [16] (see Fig. 1).…”

“…A possible alternative is to record just the initiation of debonding and calculate toughness using D = . In typical pull-out tests, however, initiation of debonding occurs well below the peak load [14,18]. In other words, data that only records peak force can not be analysed un-less debond length at that load was also recorded.…”

The energy release rate for propagation of a debond in a single-fibre pull out test was derived analytically. The key finding was that an accurate analysis can be derived by a global energy analysis that includes effects of residual stresses and interfacial friction but does not need to include the details of the stress state at the interfacial crack tip. By comparison to finite elements analysis, it was verified that the analytical results are very accurate provided the debond tip is not too close to either end of the specimen. By casting the results in terms of net-specimen stress, it was possible to derive a general energy release rate result that applies to both the pull-out test and the related microbond test. The energy release rate expressions can be used to determine interfacial fracture toughness from single-fibre pull-out tests or microbond tests.
