Ultrahigh Molecular Weight

Three ultrahigh molecular weight polyethylene (UHMWPE) composites of differing composition, reinforced with multiwalled carbon nanotubes (MWCNT) were prepared. The homogeneous distribution of MWCNT has been attempted by two dry blending methods and one melt-mixing process. The efficiency of the various methods was characterized by their effects on the quasi-static and dynamic physical properties of the composites. In the case of composites manufactured by ball milling the effects of various adhesion promoter additives (compatibilizers) has also been studied by analyzing the tensile, flexural, Charpy impact and wear properties of the composites.

Mechanical Performances

Polymer nanocomposites containing polypropylene (PP) as the polymer matrix and nanofiller aluminium hydroxide (ATH) as the flame retardant filler were compounded with various loading of maleic anhydride grafted polypropylene, MAPP (0, 1, 2, 3, 5 wt %). All materials were mixed using melt mixing process and were further prepared using an injection moulding machine. The mechanical performances of the samples were characterized using tensile and impact tests. Improvements were observed for the tensile and impact properties of the PP/ATH samples after being loaded with MAPP. MAPP loading of 1 wt % was determined to be the optimum content of coupling agent addition as this loading enabled the best performance of the nanocomposite in tensile and impact tests. Different morphologies of the fracture surfaces for all samples were characterized using FESEM analysis.

Vinyl Butyral

This work reports the preparation of SiO 2 and TiO 2/poly (vinyl butyral) nanocomposites with enhanced dynamic mechanical properties. Silica and titania nanoparticles were introduced in the matrix as the neat powder and as colloidal sol using the melt mixing process. Composites reinforced with colloidal sol silica and titania showed higher mechanical properties than the ones reinforced with as-received particles. When sol TiO 2 particles are used, the highest increase of storage modulus of about 54% is obtained for 5 wt% loading, while for sol SiO 2, the storage modulus increases with the addition of nanosilica with the largest increase of about 99% for 7 wt% loading. In addition, nanocomposites were introduced within Kevlar/PVB composites. The addition of 5 wt% silica and titania colloidal sol lead to the remarkable increase of the storage modulus for about 98 and 65%, respectively. Largest contribution of nanoreinforcements in lowering the glass transition temperature is observed for 7 wt% loading of TiO 2 and SiO 2 colloidal sol.

Good Agreement

A Cu-TiB2 composite was successfully fabricated by in-situ liquid mixing process, and its microstructure, mechanical properties as well as electrical conductivity were evaluated. For Cu-2vol.%TiB2 composite, the hardness was as high as 5GPa and the Young’s modulus was 130GPa. And hardness and Young’s modulus of Cu-6vol.%TiB2 composite was 5.6Gpa and 138GPa, respectively. With the increase of the TiB2 content, hardness and Young’s modulus of Cu-10vol.%TiB2 composite were 20 and 12%, respectively, which was higher than that of Cu-2vol.%TiB2 composite. Young’s modulus of the Cu-TiB2 composite in this paper was in good agreement with the prediction by Hashin-Shtrikman (H-S) model. Furthermore, the electrical conductivity of the Cu-TiB2 composite showed its maximum value of about 78%IACS and decreased with the increase of the TiB2.
