Special Issue Information

Dear Colleagues,

Advanced Fiber Reinforced Polymers (FRP) have been widely used in aerospace and automotive industries, as well as other fields due to their excellent thermo-mechanical properties, and high strength-to-weight ratio. The polymer blends with fiber as additives are also included in FRP in this special issue. Synthetic fibers, chemical fibers, natural fibers, nanofibers, and other fibrous substances can be used to reinforce polymers. The polymer matrix can be thermoplastic and thermoset with different shapes according to their applications. 

The Special Issue focuses on advanced fiber-reinforced polymers and advanced FRP composites. The main research includes but is not limited to the structure design and process methods of Advanced FRP, the modification of fiber and polymer materials, the bonding and debonding between fiber and polymer matrix, the simulation of dispersion, and failure of Advance FRP, and the interface and surface problems.

Abstract
Ultra-high molecular weight polyethylene (UHMWPE)/high-density polyethylene (HDPE) blend with lower viscosity is more suitable for melt spinning compared to pure UHMWPE; however, the mechanical property of the blend fiber is hard to dramatically improve (the maximum tensile strength of 998.27 MPa).

Ultra-high molecular weight polyethylene (UHMWPE)/high-density polyethylene (HDPE) blend with lower viscosity is more suitable for melt spinning compared to pure UHMWPE; however, the mechanical property of the blend fiber is hard to dramatically improve (the maximum tensile strength of 998.27 MPa). Herein, different content modified-nano-SiO2 is incorporated to UHMWPE/HDPE blend fiber. After adding 0.5 wt% nano-SiO2, the tensile strength and initial modulus of UHMWPE/HDPE/nano-SiO2 fiber are increased to 1211 MPa and 12.81 GPa, respectively, 21.57% and 43.32% higher than that of UHMWPE/HDPE fiber. Meanwhile, the influence of the nano-SiO2 content on the performance for as-spun filament and fiber are emphatically analyzed. The crystallinity and molecular chain orientation of as-spun filament reduces with the addition of nano-SiO2. On the contrary, for fiber, the addition of nano-SiO2 promoted the crystallinity, molecular chain orientation and grain refinement more obvious at a lower content. Furthermore, the possible action mechanism of nano-SiO2 in the as-spun filament extrusion and fiber hot drawing stage is explained. Full article
