In order to improve the strength and brittleness of ceramsite concrete, polypropylene fiber was added to ceramsite concrete in this study. A total of 180 polypropylene fiber-reinforced ceramsite concrete specimens were prepared, and cube compressive test, splitting tensile test, axial compressive test and elastic modulus test were carried out. The results show that polypropylene fiber can effectively improve the splitting tensile strength and tension-compression ratio of ceramsite concrete, and has little effect on compressive strength and elastic modulus. Based on the experimental results, the conversion relationship model between splitting tensile strength and cube compressive strength, axial compressive strength and cube compressive strength, and the numerical model of elastic modulus of polypropylene fiber-reinforced ceramsite concrete were proposed.

With the development of miniaturized wearable electronics，flexible energy storage devices with soft，flexible，small size，and high energy density have attracted widespread attention. Aramid nanofibers (ANF) were utilized as fiber reinforcement and pillared structure materials to prepare MXene/ANF flexible self-supporting electrode through vacuum filtration, which were subsequently assembled into all-solid-state symmetric supercapacitors.With the increase of ANF content to 15%，the mechanical properties of MXene/ANF self-supporting electrode increase to 151.5 MPa，while the conductivity decrease to 1371.1 S/cm. The MXene/ANF Self-supporting electrode shows a high specific capacitance of 432.7 F/g at the current density of 1 A/g. The assembled symmetric all-solid-state supercapacitors exhibit excellent mechanical flexibility and remarkable cycling stability,with an energy density of 25.7 Wh/kg at the power density of 523.1 W/kg and about 88.9% capacitance retention over 10000 cycles.

The vibration response of fiber-reinforced composite thin shell was analyzed based on the multilevel correction technique. Firstly， the theoretical model was established by considering the influence of fiber orientation， and the vibration response was solved by using the Ritz method. Next， the more precise theoretical model of composite thin shell was obtained by using the multi-level correction technique and the experimental data. Finally， T300 fiber/epoxy composite thin shell was taken as the study object and the laser scanning test system was set up to obtain the first 6 natural frequencies， modal shapes and vibration responses. By comparing the experimental resonant response results with the calculated results after adopting the multilevel correction technique， it was found that the calculation error is in the range of 5.2%~14.3%， which is within an acceptable level， and thus the correctness of the above analytical method was verified.

Calcium phosphate cement (CPC) is well known for the excellent bioactivity and biocompatibility, however, CPC has been used only for the repair of non-load bearing bone defects due to its brittle nature and low flexural strength. Polymer reinforced CPC has been considered as one of the most effective strategies for mechanical reinforcement. This paper summarizes various kinds of polymers loaded CPC:fiber reinforcement, microsphere reinforcement and dual setting cements. It is aimed to analyze the advantages, disadvantages and principles of the polymers reinforced CPC, and so as to lay a foundation for the further research of improving and manufacturing the CPC with ideal mechanical properties.
