“…The value of ILSS t was calculated to determine the effect of silane treatment on adhesion with the phenolics matrix as follows t~3 F 4dl (6) where F, d and l are the breaking load, the specimen thickness and width respectively. Figure 6 summarises the effects of the coupling agents on the ILSS of silica fibre reinforced phenolics composites.…”

The effects of fibre surface silanisation on silica fibre/phenolics composites produced by the resin transfer moulding (RTM) solution impregnation route were investigated. Diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy and micro-Wilhelmy method were used to evaluate the surface properties of silanised silica fibre. The interlaminar shear strength (ILSS) measurements and morphological observations of the silica fibre/phenolics composites were also performed. The interactions occurring between silica fibre and the components of phenolic resin solution affect the dynamic adsorption behaviour of phenolic resin onto fibre reinforcement. The competitive adsorption of ethanol as solvent onto silica fibre suppresses that of phenolic resin. Fibre surface silanisation by c-aminopropyl-triethoxysilane (c-APS), c-glycidoxypropyl-trimethoxysilane (c-GPS) and c-methacryloxypropyl-trimethoxysilane (c-MPS) leads to the improvement of mechanical interfacial properties of silica fibre/phenolics composites on one hand and decreases the inhomogeneities of resin distribution and mechanical interfacial properties at different regions of the RTM product on the other hand.

“…Steenkammer and co-workers [99,100] and Grif®n et al [95] have both reported signi®cant differences in the permeabilities measured in notionally similar reinforcement stacks when the permeating¯uid is changed. There is scope for an extensive study of the interrelationship between permeability and the microstructure parameters controlling the¯ow process.…”

“…This approach is often referred to as the drag theory of permeability and has been used to model the fluid flow characteristics of glass wool (Jackson and James 1986), beds of synthetic polymer fibers (Jackson and James 1986), biological polymers (Jackson and James 1982), and composite fiber preforms (Steenkamer et al 1995). This approach assumes that the flow fields around each fiber have minimal interaction and, consequently, has limited application even in the limit of high porosity materials (i.e., >95% porous) (Skartsis et al 1992).…”

Two- and three-dimensional structural models of the vertebral body have been used to estimate the mechanical importance of parameters that are difficult to quantify experimentally such as lattice disorder, trabecular thickness, trabecular spacing, connectivity, and fabric. Many of the models that investigate structure-function relationships of the vertebral body focus only on the trabecular architecture and neglect solid-fluid interactions. We developed a cellular solid model composed of two idealized unit cell geometries to investigate the continuum and micro-structural properties of human vertebral cancellous bone in a mathematically tractable model. Using existing histomorphological data we developed structure-function relationships for the mechanical properties of the solid phase, estimated the micro-structural strains, and predicted the fluid flow characteristics. We found that the micro-structural strains may be 1.7 to 2.2 times higher than the continuum level strains between the ages of 40 and 80. In addition, the predicted permeability agrees well with the experimental data.
