The Stability

The silver particles were grown in situ on the surface of wood by the silver mirror method and modified with stearic acid to acquire a surface with superhydrophobic and antibacterial properties. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and X-ray energy spectroscopy (XPS) were used to analyze the reaction mechanism of the modification process. Scanning electron microscopy (SEM) and contact angle tests were used to characterize the wettability and surface morphology. A coating with a micro rough structure was successfully constructed by the modification of stearic acid, which imparted superhydrophobicity and antibacterial activity to poplar wood. The stability tests were performed to discuss the stability of its hydrophobic performance. The results showed that it has good mechanical properties, acid and alkali resistance, and UV stability. The durability tests demonstrated that the coating has the function of water resistance and fouling resistance and can maintain the stability of its hydrophobic properties under different temperatures of heat treatment.

Reinforced Plastic

Carbon fiber reinforced plastic (CFRP) is a composite material in which carbon fibers are impregnated with resin to achieve both high strength and high rigidity. CFRP is an excellent material, but it is expensive in terms of materials, manufacturing costs, and capital investment, and it takes a lot of time to complete a product. In order to solve these problems, the demand for de-autoclaving has been increasing in recent years. If molding can be performed without autoclaving, it will be possible to reduce costs and improve productivity in terms of materials and capital investment costs.

Sic Composites

3D C/SiC composites were fabricated by polycarbosilane (PCS) infiltration and pyrolysis process. The influence of pretreatment of carbon fiber, including pyrolytic carbon coating and thermal treatment, on mechanical properties of C/SiC composites was investigated. The results showed that the composites without fiber pretreatment had a flexural strength of 154MPa and a fracture toughness of 4.8 MPa•m1/2, while those with carbon coating or thermal treatment had much higher strength and toughness, that is, more than 400MPa and 15MPa•m1/2 respectively. Weak interfacial bonding and better in-situ strength of carbon fiber were main reasons for mechanical property improvement with pretreated carbon fiber.
