Do really reverse osmosis (RO) membranes need modification to cover their disadvantages or enhance their efficiency? Are there any defects in RO membranes manufacturing that require modification? These questions are discussed here in this short review. Through the world, there are thousands of patents, publications, and PhD theses dealing with surface modification and grafting of RO membranes. This growing phenomenon should attract the attention of the scientific community for technologic and economic reasons. Due to the increasing water pollution levels, which overpassed the RO membranes capacities, there is an urgent need to manufacture RO membranes, with multidisciplinary characteristics and high performance regarding both salts removal and fouling resistance, before sending them to the market and avoiding to think to their following modification.

“…the Young's modulus of the composites were calculated [8,9]. Figure 8 shows the model that was proposed for the case when the matrix slips past the particle appears to be accurate for higher concentrations.…”

“…Up to this particular weight content of filler, the adhesion between the particle and the matrix is ideal; after this, the amount of resin can no longer encapsulate the particles completely, leading to the generation of a large number of voids, thus lowering the Young's modulus of the composites. [6][7][8] The values from Neilsen's model rose steadily and can be argued to be too high because his model is only suitable for low concentrations of filler. The filler in this study is up to 35 wt%.…”

“…10 Figure 9 shows the values of Young's moduli obtained from Neilsen's model, Einstein's theory and experiments, post-cured in microwaves. 5,8 It can be found that the Einstein's model predicted the Young's modulus of the composites quite accurately at lower particulate loading (up to 15 wt% of glass powder), but it was incorrect at higher concentration of fillers. The adhesion between the particle and the matrix was no longer ideal after this wt% of filler.…”

“…The Young's modulus of resins reinforced with particulate fillers will usually increase slowly to a maximum at a particular filler loading depending on the attributes of the filler, but usually at low concentration of filler. Up to this particular weight content of filler, the adhesion between the particle and the matrix is ideal; after this, the amount of resin can no longer encapsulate the particles completely, leading to the generation of a large number of voids, thus lowering the Young's modulus of the composites[6][7][8]. The values from Neilsen's model rose steadily and can be argued to be too high because his model is only suitable for low concentrations of filler.…”

This paper discusses a simplified approach to analyse the mechanical properties of randomly distributed particulate composites. Mechanical properties of glass powder filled vinyl ester resins were experimentally investigated. The analytical results were compared with experimental results and a very good correlation was found. Further, the experimental results and the predictions showed that the strength of the composites is less than the strength of the matrix material, for all three composites tested.
