Traditional inefficient "tentative" trial and error experiments are difficult to rapidly and efficiently prepare synthetic fiber/cellulose composites with high thermal stability and strong insulation properties because the direct scientific theory or simulation guidance is insufficient. In this paper, PI fiber is the first time introduced to cellulose insulating paper. The mechanical, thermal stability, and dielectric properties of PI/cellulose composite insulating paper are predicted by molecular dynamics (MD) simulation. The composite insulating papers with the corresponding content of PI fiber were prepared and their thermal stability, mechanical properties, and electrical properties were investigated. Relative to the pure cellulose insulating paper, the 6% PI/cellulose insulating paper is the most representative, its tensile strength increased by 26.24%, the glass transition temperature increased from 113.4 to 124.7 K, permittivity decreased from 4.22 to 3.25, the dielectric loss decreased by 58.33% at 50 Hz, and the breakdown strength increased by 30.35%. This work confirms the effectiveness of MD simulation to rapidly guide the preparation of the new composite insulating paper, which can provide a reference for the future expansion and development of synthetic fiber in the preparation of cellulose insulating paper, and proves that PI fiber can enhance the thermal stability and insulation properties of cellulose insulating paper.

This paper investigates the quasi-static mechanical properties and damage behavior of flexible composites prepared from high-performance glass fiber-based multi-axial warp knitted fabrics as reinforcement and high tenacity environmentally friendly thermoplastic polyurethane as a matrix. The composites were produced by attaching thermoplastic polyurethane (TPU) to the top and bottom of the fabric using a vulcanization machine, followed by hot-pressing for different temperatures and time settings. Moreover, the effects of different preparation processes on the tensile strength, static puncture resistance, and tear strength of flexible composites were investigated in this paper. The results indicated that both hot-pressing temperature and vulcanization time had a significant impact on the mechanical properties of the composites. With an optimum vulcanization temperature of 185°C and a vulcanization time of 10 min, the composite provides optimum tensile strength and puncture resistance. Tear strength is the worst and is related to the reinforcement’s organisational structure and the interfacial bond’s strength. The results of this study are of theoretical and practical significance for applying high-performance multi-axial warp-knitted flexible composites as raw materials in the construction field.

“…[23][24][25][26] The resulting flexible composites exhibit high tensile and impact strength, making them appealing for various high-performance industrial applications such as construction, aerospace and military. 27 Moreover, these composites are also interesting for applications where high-end mechanical properties are not required, such as apparel, furniture, damping elements or artificial leather. For example, Wool patented a bio-based leather-like material based on functionalized plant oils reinforced with natural fibers, 28 which was used to manufacture footwear.…”

“…For woven reinforcements, the approach of using flexible polymers to achieve flexible composites was realized by using natural rubber, 15–18 polyvinyl chloride 19–22 or shear‐thickening fluid 23–26 . The resulting flexible composites exhibit high tensile and impact strength, making them appealing for various high‐performance industrial applications such as construction, aerospace and military 27 .

The tensile behavior of a flexible epoxy resin reinforced with knitted reinforcements from various fiber materials was comprehensively studied in the wale and course direction. By measuring dry yarns, temperature‐treated yarns, dry knitted fabrics and flexible composites, the effect of the fiber material and the knitted fabric on the tensile properties was analyzed. The interlock knit structure strongly affected the deformation behavior of the flexible composites which differed significantly from the dry knitted fabrics. The deformation behavior of the flexible composites was monitored using digital image correlation which revealed the formation of cracks and high local strain differences in the course direction for all fiber materials. This was linked to fiber‐matrix debonding by scanning electron microscope observations. In the wale direction, the deformation of the knitted structure under tensile load led to plastic deformation of the matrix material. Overall, with yarns from recycled thermoplastic fibers, a higher maximum stress and strain at break was achieved compared to bio‐based fibers. However, irreversible damage occurred for all fiber materials at similar strain values.Highlights Tensile tests on yarns, knitted fabrics and flexible composites.
