“…This fact was evidenced by the larger average size in the nanocomposite, 263±96nm, since the untreated TiO 2 used has an average diameter of 164±33nm 24 . The same effect was verified by Sudirman et al (2012), when silica was added in unsaturated polyester resin 19 and by Silva et al (2013) with polyurethane and TiO 2 24 . The EDS spectra of nanocomposites (Figure 6d, 6f and 6h) evidenced an increase in the Ti peak compared to the pure polymer (Figure 6b) and confirm the incorporation of the TiO 2 filler in the APE matrix.…”

“…When the filler content increases, the intensity of this band decreases and its position is shifted toward lower wavenumber as an effect of the interaction of the OH groups on the TiO 2 surface with the ester group of polymer matrix (Scheme 1). This behavior was also observed by Sudirman et al (2012) for nanocomposites formed between aliphatic polyester resins and silica 19 20 . Figure 2 illustrates the X-ray diffraction patterns of TiO 2 , pure APE and the synthesized APE/TiO 2 nanocomposites.…”

“…4 showed the absorption bands at 1701.22 cm -1 which is attributed to carbonyl stretch group (C=O), band at 1600.91 cm -1 is stretched due to aromatic ring group, unsaturated bonding (C=C) at 1070 cm -1 as deformation peak. Meanwhile the FTIR of composites shows additional peak at 1268-1132 cm -1 assigned as vibration of asymmetric stretching of Si-O-Si bonds and the band at 996 cm -1 is Si-OH because clam shell particles contained silicate groups, which is supported by Sudirman et al [16].…”

The composite materials is growing rapidly in the automotive and constructive industries, especially those composites which consist of unsaturated polyester resin matrices. It has low viscosity and hardness at room temperature when a catalyst is added. Polyester resins have rigid and slightly brittle properties, more thermal resistance to heat, flexible insulation properties, and adhesion chemical resistance, which are easy to process, molding and affordability [1]. To improve the mechanical properties of polyester resin, fillers are added. Fillers of polyester resin composites are usually fibers glass, because of compatibility between the matrix properties and fillers [2]. Natural fillers and compounds of fiber glass with natural fillers [3] are tends for polyester composites produced to have good mechanical properties. Research on unsaturated polyester resin filled with natural ingredients has been carried out, using clam shells [4], lontar fruit fibers [5], eggshell powder [6], snail skin powder [7] and CaCO3 [8]. In this study the fillers used are clam shells. Utilization of clam shells research in Indonesia is not optimal because it is used as a craft or decorative art. Clam shells contains calcium carbonate compounds of 94-99 % (total overall weight of shell) [9-13] carbonate groups (CO3 2−), 0.51 % magnesium

This work focuses on the release of nanoparticles from commercially used nanocomposites during machining operations. A reliable and repeatable method was developed to assess the intentionally exposure to nanoparticles, in particular during drilling. This article presents the description and validation of results obtained from a new prototype used for the measurement and monitoring of nanoparticles in a controlled environment. This methodology was compared with the methodologies applied in other studies. Also, some preliminary experiments on drilling nanocomposites are included. Size, shape and chemical composition of the released nanoparticles were investigated in order to understand their hazard potential. No significant differences were found in the amount of nanoparticles released between samples with and without nanoadditives. Also, no chemical alteration was observed between the dust generated and the bulk material. Finally, further developments of the prototype are proposed.
