It is possible nowadays to produce new cheaper aluminum-based composites such as aluminum borate (Al18B4O33) whisker reinforced ones and aluminosilicate (Al2O3×SiO2) short fiber reinforced ones at even low cost [1-10].
Fig.1 is the X-ray diffraction (CuKα, λ = 0.1542 nm) pattern of the mullite fibers, which is the same as that of ref. [16, 17].

Fig. 1: The solubility of ketoprofen inclusion complexes with β-CD and HP β-CD depending on water temperature (20ºC), molar ratio 1:1 and 2:1, in solution (MI) and in suspension (MII) Solubility of ketoprofen-β-cyclodextrin complex (2:1) and ketoprofen-hydroxypropyl β-cyclodextrin (2:1) takes low values, which indicates that the cyclodextrin molecules can include two molecules of ketoprofen but not provide a better solubility (Fig. 2).
Fig. 2: The solubility of ketoprofen inclusion complexes with β-CD and HP β-CD depending on water temperature (50ºC), molar ratio 1:1 and 2:1, in solution (MI) and in suspension (MII) Inclusion compounds that have been compressed to form tablets 9 mm in diameter were subjected to tribological tests and are characterized by exposed parameters in (Table 1).
Ketoprofen inclusion compounds of β-cyclodextrin and hydroxypropyl-β-cyclodextrin in a 1:1 molar ratio presents height solubility than those in a 2:1 molar ratio and complexes formed with hydroxypropyl-β-cyclodextrin is more soluble than those obtained with β-cyclodextrin.
