Flax yarn and PP filament can be made into flax/ pp lapping yarn. Weaving with the lapping yarn, and finally can crank the fabric into PP/ flax composite by hot pressing. Research on the thickness of composite material and the peeling properties of the composite material, we analyzed the correlative factors about the producing technics of composite by orthogonal experimental method. The results showed that the material’s thickness and the technics are the main influencing factors of the wettability, and forecast the technics of composite molding process to get the best wettability properties.

ZrB2-SiC-BN ultrahigh-temperature ceramic (UHTC) was fabricated by hot-pressing at 1800°C under 23MPa pressure of argon. Compared to ZrB2-SiC, the flexural strength of ZrB2-SiC-BN composite material was enhanced by adding 30% BN, and the fracture toughness showed a slight decrease, while the hardness decreased sharply. The addition of 30% BN also noticeably improved the machinability of the composites. Furthermore, ablation resistance tests were carried out using an oxyacetylene torch under subsonic conditions. Results indicated that a coherent compact scale of zirconium silicate was formed, which acted as an effective barrier against the inward diffusion of oxygen.

Practical Applications

Effect of whisker orientation on mechanical properties of hydroxyapatite-SiCw composite bioceramics was studied in this paper. Experiment results show that the mechanical properties of the material are the best when the tensile stress acted on the composite material is parallel with the hot pressing plane or the shearing stress is normal to the hot pressing plane, and they are the worst when the tensile stress acted on the composite material is normal to the hot pressing plane or the shearing stress is parallel with the hot pressing plane. This will offer great guidance for practical applications of the hydroxyapatite-SiCw composite bioceramics.

Two-dimensional carbon fiber fabric T300 used as reinforcement, Cf/Al composite material was prepared by hot pressing diffusion. Effect of parameters on microstructure of Cf/Al composite material was studied. We found that for aluminum foil used as matrix, hot pressing temperature is 650°C, hot pressing time is 20min, pressure is 30MPa. As a case, interfacial reaction product Al4C3 accounts for 3.6%, and composite material density is 2.44g/cm3. For aluminum powder used as matrix, hot pressing temperature is 620°C, hot pressing time is 35min, pressure is 10MPa. As a case, Al4C3 accounts for 2.8%, and composite material density is 2.58g/cm3. The molding of aluminum powder is much easier than that of aluminum foil. The latter requires higher hot pressing temperature. Interfacial reaction product Al4C3 increases as increasing of hot pressing temperature and pressure.

Thermal management has become one of the crucial factors in designing electronic equipment and therefore creating composites with high thermal conductivity is necessary. In this work, a new insight on hybrid filler strategy is proposed to enhance the thermal conductivity in Thermoplastic polyurethanes (TPU). Firstly, spherical aluminium oxide/hexagonal boron nitride (ABN) functional hybrid fillers are synthesized by the spray drying process. Then, ABN/TPU thermally conductive composite material is produced by melt mixing and hot pressing. Then, ABN/TPU thermally conductive composite material is produced by melt mixing and hot pressing. Our results demonstrate that the incorporation of spherical hybrid ABN filler assists in the formation of a three-dimensional continuous heat conduction structure that enhances the thermal conductivity of the neat thermoplastic TPU matrix. Hence, we present a valuable method for preparing the thermal interface materials (TIMs) with high thermal conductivity, and this method can also be applied to large-scale manufacturing.

Infiltration Pressure

The critical infiltration pressures of the matrix in a two-dimensional (2D) carbon fiber preform were calculated theoretically, and the calculated values of the static and dynamic models were 0.115 and 0.478 MPa, respectively. Compared with the dynamic model, there is no viscous resistance or infiltration front gas pressure in the static model, so the static value is obviously lower than the dynamic value. To verify the rationality of theoretical calculation, 2D carbon fiber reinforced plastics (2D-CFRP) with infiltration pressures of 0.5, 0.6, 0.7, 0.8, and 0.9 MPa were prepared by the vacuum infiltration hot pressing molding process. The microstructure of the composite was observed and the bending strength was tested by three-point bending test. The results show that the infiltration pressure has an important influence on the infiltration effect and the bending fracture morphology. When the infiltration pressure is 0.7 MPa, the composite has an excellent infiltration effect. The fibers distribute reasonable in the fracture. Stress can be effectively transferred when the composite material is loaded. And the bending strength of the composite material reaches 627 MPa at this time.

The SiCp/Al-30Si composite material was prepared by hot-pressing. The microstructure was characterized by means of optical microscope and SEM, the thermal expansion performance was tested by PYC-Ⅲ Thermal Expansion Coefficient Tester. It was researched that the influence of SiC particle size and manufacture technology on the microstructure and thermal expansion coefficient. Results show that shortening soaking time decreases the number and the size of the nascent and precipitating Si particles, enlarges the CTE of the composite; lager pressure is beneficial to reduce the CTE of the composite, and the larger the pressure is, the more compact microstructure is and the less number of holes are. Thermal expansion performance of the composite was influenced by SiC particle size, distribution of matrix phase, trait of interface combination and the holes.
