Research on the Influence of Polyacrylonitrile Precursor on the Properties of Carbon Fibers and Pultruded Composite Materials

Zheng Wei — 2025-09-08

Polyacrylonitrile (PAN) precursor is a core precursor for the preparation of high-performance carbon fibers. Its unique chemical structure and physical properties directly contributes to the microstructure and mechanical properties of carbon fibers, and therefore affect the overall performance of pultruded composites. This study systematically investigated the influence of PAN precursor properties on the degree of graphitization, surface morphology and mechanical properties of carbon fibers by regulating the molecular weight distribution, stretching ratio and impurity content of PAN precursor, and analyzed the mechanism of action of carbon fiber properties on the interfacial bonding strength and tensile/bending properties of composites in combination with the pultrusion process. The results showed that when the filament stretchability was increased to 4.5 times, the axial orientation of carbon fibers increased by 18% and the tensile strength reached 520 MPa; Filaments with impurity content below 0.3% increase carbon fiber yield by 5.2% and interlaminar shear strength of composites by 23%. This study provides a theoretical basis for raw material screening and process optimization of high-performance carbon fibers and their composites.

Experimental Design and Material Properties Research of the Reinforced UHPC Columns

Jiaqi Duan — 2025-09-04

Medium shear span ratio reinforced columns are prone to complex failure under seismic action. This paper compares the seismic performance of normal concrete columns and UHPC columns by introducing ultra-high-performance concrete (UHPC). The shear span ratio (2.4-4.4) and axial compression ratio (0.10, 0.36) were used as variables, and the bearing capacity, ductility and failure mode were analyzed through low-cycle reciprocating loading studys. The results showed that UHPC significantly improved the bearing capacity, stiffness and energy dissipation capacity of the column, and suppressed the crushing and spalling of concrete. When the shear span ratio is 2.4 and the axial compression ratio is 0.36, the failure mode of UHPC columns was changed from shear failure to flexural shear failure. Thus this study can become a reference for the seismic design of UHPC columns.

Yajun Fan — 2025-09-04

Airborne LiDAR (Light Detection and Ranging) is an evolving high-tech active remote sensing technology that has the capability to acquire large-area topographic data and can quickly generate DEM (Digital Elevation Model) products. Combined with image data, this technology can further enrich and extract spatial geographic information.

UHPC Reinforcement of Damaged RC Beams under Load Conditions Cracking and Bending Performance

Xuezhi Wang — 2025-09-08

In order to study the mechanical properties of damaged reinforced concrete (RC) beams reinforced with ultra-high-performance concrete (UHPC), a four-point bending test was conducted to systematically investigate the influence of factors such as the number of reinforcement surfaces and the degree of damage. The results indicate that single-sided repaired beams have certain advantages in crack resistance performance, but are more disadvantageous in ultimate bearing capacity, with obvious debonding phenomenon before the end of loading. Compared with single-sided reinforcement, the cracking load of the three-sided reinforced beam increased by an average of 1.85 times, the ultimate bearing capacity increased by an average of 177.5%, and a good UHPC-RC combination effect could be formed, which could work synergistically until the end of loading. The degree of pre damage has a significant impact on the crack resistance performance of reinforced beams, while its impact on the ultimate bearing capacity is relatively limited. When the pre splitting width of the RC beam increases from 0.2 mm to 0.4 mm, the ultimate bearing capacity decreases by 28.33%. Finally, a calculation formula for the ultimate flexural bearing capacity of damaged RC beams reinforced with UHPC was proposed, taking into account the degree of pre damage to the RC beams and the three-sided repair. The calculated results showed a high degree of agreement with the experimental data.
