A smart material is used as spectacle frames and brassiere frames, and partly in medical supplies because of its shape memory effect. The smart composite can be used on the wing of an airplane instead of the existing aluminium to control crack propagation. In this study, the smart composite was fabricated by a hot press method. TiNi alloy as reinforcement and Al6061 as matrix were used, respectively. The mechanical properties of the smart composite under thermal shock cycles were evaluated. In addition, Acoustic Emission techniques were also used to clarify the damage behavior of the smart composite under thermal shock cycles nondestructively.

The combination between synthetic polyolefin with natural polymer such as cellulose, starch and chitosan can stimulate biodegradation processes of waste plastics such as polyethylene (PE), polypropylene (PP) and other conventional plastics. In this work, PVC (polyvinyl chloride) biocomposite was prepared by compounding cellulose particle into PVC matrix in the presence of PVC-g-maleic anhydride as a compatibilizer. Cellulose nanoparticles were prepared by physical top-down method after milling by using High-Energy Ball-mill. The diameter size of cellulose nanoparticle was obtained as 170 nm. Cellulose particles were added as filler with ratio of 10-30 phr in PVC matrix. PVC biocomposites was prepared as a sheet film with the thickness of 0.3 mm by hot-press method. The addition of cellulose particle into PVC matrix was examined in various filler volumes and various cellulose particle sizes. The obtained PVC composite films were characterized by means of Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA) and Fourier-Transformed Infrared (FTIR) spectroscopy. The rheological and mechanical properties of PVC and cellulose composites were investigated as a function of surface structure and filler volume fraction.

Fabrication And Characterization

A new kind of Hydroxyapatite (HA) composites was fabricated using a hot-press method in which carbon nanotubes (CNTs) were introduced to the HA ceramic matrix to improve the mechanical properties of the resulting composites. The CNTs were treated using a mixture of nitric acid and sulfuric acid. A homogeneous dispersion of the CNTs in the HA matrix was achieved through dispersing them in the solution of surfactant. The bioactivity of the samples was tested. The microstructures of HA/CNT ceramic composites and the sample surfaces after immersion in SBF were characterized by SEM. The results showed that the introduction of the CNTs into HA ceramic matrix could produce positive strengthening effect without impairing the biological properties of the HA ceramic.

AbstractIn this study, composites of knitted fabric made from side-by-side multiple glass and polypropylene yarns have been investigated. These composites have been produced by a new manufacturing method – the hot press method. By using various knitted fabrics made from different components of glass and polypropylene yarns, several types of knitted structures and yarn components were investigated: rib 1-1, full Milano and full cardigan. The mechanical properties of composites were measured in three directions. The results showed that hot-pressed knitted composites of glass and polypropylene yarns have high strength, impact resistance, work-to-break and elongation, simultaneously. The highest bending resistance and maximum stiffness are achieved for rib-knitted composites consisting of 8 wt% glass and 92 wt% polypropylene yarns. The highest impact energy absorption was obtained with 18 wt% glass content and 82 wt% polypropylene matrix.

The multi-walled carbon nanotubes (MWNTs) were added into the phenolic resin to fabricate MWNTs/phenolic nanocomposites. The pressure and temperature were applied to cure MWNTs/phenolic compound by hot press method, then followed by a post curing process. The results showed that post-curing of the nanocomposites specimen is necessary for better mechanical properties. The temperature used for post curing should be higher than the curing temperature. The higher curing pressure improved the Young’s modulus of the nanocomposites. The tensile failure morphologies of MWNTs/phenolic nanocomposites were examined using field emission scanning electron microscope (FESEM) to evaluate the effects of manufacturing processes on the mechanical properties of MWNTs/phenolic nanocomposites.

Si Addition

TiAl/Ti5Si3 in situ composites were successfully fabricated by reactive hot-press method from powder mixtures of Ti, Al and Si. The influence of the Si addition on the microstructures and mechanical properties of TiAl/Ti5Si3 composites was investigated in detail. The results show that an appropriate amount of addition of Si refined the matrix structure obviously due to the in situ formed Ti5Si3, and as a result, the flexural strength and fracture toughness of the composites are modified. When the Si content is 1.82 wt %, the flexural strength and the fracture toughness reach the maximum value of 685.67 MPa and 9.02 MPa·m1/2, respectively. The enhancing mechanism was also discussed.
