Ceramic-fiber composites have important applications in protection field. In this work, the stable and reliable resin reinforced fiber-ceramic-fiber (RRFCF) composites with sandwich structure were prepared by using the vacuum assisted resin transfer molding (VARTM) process. The mechanical properties of the prepared RRFCF composites with different configurations were studied. Results showed that the thickness values of the glassfiber-reinforced plastic layers (panel thickness: ta and backplane thickness: tc) had significant influences on the unique mechanical properties of the RRFCF composites. The stress distribution of RRFCF composites with different configurations under loading was analyzed by simulation. The fatigue behaviors of Z-type (ta < tc) and F-type (ta > tc) RRFCF composites were investigated and found to be in good agreement with the simulated results. Moreover, the flexural strength and modulus of Z-type composites were obtained and found to be higher than those of F-type composites. These results have important guiding significance for the engineering application of RRFCF composites.

Fiber Reinforced Thermoplastics

The application of Fiber Reinforced Thermoplastics (FRTP) is expected to reduce the weight of automobiles. The press and injection hybrid molding method was developed to mold FRTP with high strength and high stiffness by giving complicated shapes such as ribs and bosses to the outer shell structure of FRTP with continuous fiber. However, as this method uses high-cost FRTP laminated sheets, it is necessary to develop a low-cost FRTP manufacturing process. In this study, we aim at the development of Melted Thermoplastic-Resin Transfer Molding (MT-RTM) to mold FRTP with complicated shape at low cost by injecting melted short fiber reinforced thermoplastics into dry fabric. The effects of press condition on the mechanical properties of GFRTP molded by MT-RTM were clarified by bending tests. GFRTP molded at high mold temperature and high closing speed showed high mechanical properties because of good impregnation of injection resin into continuous fabric in the outer shell structure.

Vartm Process

In the present study, we contrast the change of mechanical and physical properties between VaRTM (Vacuum Assisted Resin Transfer Molding) and hand lay-up process. In the results of mechanical tests, VaRTM specimen is stronger than hand lay-up specimen and hand lay-up specimen became delamination. In the results of physical tests, the resin content of VaRTM specimen is lower than hand lay-up specimen. On micrograph, the strength of specimen by VaRTM between fiber and resin is stronger than that of one by hand lay-up. And the specimen by hand lay-up contains more defects than one by VaRTM. So, VaRTM process can practically apply for automobile engine hood. This paper shows that VaRTM process is one of the most suitable processes for composite parts of automobile.

Supercritical Fluid Drying

Aerogel composites were prepared by immersing ceramic fiber into silica aerogel precursor via supercritical fluid drying. The mechanical behavior of silica aerogel composites was investigated with shrinkage, tension, bending and compression. The influences of fiber volume fraction, aerogel density and heat treatment were examined. After reinforced by ceramic fiber, the shrinkage of aerogel and aerogel-fiber composites was retarded obviously. The mechanical property of aerogel-fiber composites increased first and then decreased with increasing fiber volume fraction from 5.8% to 11.5%. For a given fiber volume fraction, the mechanical strength enhanced with increasing aerogel density. In addition, the mechanical property of aerogel composites did not decrease but increased after heat treatment at 600°C.
