“…To enable cryogenic applications of epoxy fibre-composites, it is important to enhance their damage tolerance, i.e. fracture toughness [3], and to suppress matrix microcracking under super cold temperatures [4,5]. One major method to improve the mechanical and fracture properties of epoxies at cryogenic temperatures, i.e.…”

“…In a context of diminishing resources and climate change, the need to shift to a more sustainable society implies changing the way materials are designed, used, and discarded. For example, fiber-reinforced polymers (FRPs), combining lightness with high strength and stiffness, have been used in various fields, including the aerospace, automotive, civil engineering, construction, and the medical equipment industries [1][2][3][4][5][6][7]. However, traditional FRPs, reinforced with glass or carbon fibers, use petroleum-based resins and raise end-of-life issues.…”

Cellulose acetate (CA) is widely used as an alternative to conventional plastics because of the minor environmental impact of its decomposition cycle. This study synthesized five-layer environmentally friendly composites from CA bioplastic and basalt fibers (BFs) to produce a high-strength marine-biodegradable polymer. Maleic anhydride-grafted polypropylene (PP-g-MAH) was mixed with CA as a surface-active agent (SAA) to understand the effect of surface treatment on the mechanical properties of the composite. Tensile tests and scanning electron microscopy were conducted to observe the fracture surfaces. The ultimate tensile strength (UTS) of the BF/CA composite increased by approximately a factor of 4 after adding 11 vol.% unidirectional BF. When the SAA was added, the UTS of the composite with 11 vol.% BF was multiplied by a factor of about 7, which indicates that the surface treatment has a significant positive effect on the mechanical properties. However, the improvement is not apparent when the added BFs are in a plain weave with a vertical orientation. A photodecomposition experiment was then conducted by adding TiO2. Observing the UTS changes of the CA and BF/CA composites, the effect of the photocatalyst on the decomposition of the materials was explored.

“…Nevertheless, the environmental temperature has a remarkable influence on the mechanical performances of composite sandwich structures, which result in the potentially dangerous for the engineer applications of these structures. [24][25][26] Recently, a few research works have been done to evaluate the quasi-static indentation performances and damage mechanism for sandwich structures under varying temperatures. Li et al [27] investigated the quasi-static indentation performances and deformation behaviors for sandwich beam at elevated temperatures.…”

The influences of elevated and cryogenic temperature on the quasi-static indentation responses and damage mechanism for composite Y-type cores sandwich structure were studied by experiments in present paper. The quasistatic indentation experiments were performed to explore the indentation performances for composite Y-type cores sandwich structures under eight different temperature conditions. The influences of the testing environment temperature on the typical indentation force-deformation curves, damage patterns and indentation failure load were investigated and analyzed. The experimental results demonstrated that the testing environment temperature made an important influence on the deformation mechanism, typical forcedeformation curves and failure load. Fiber fracture of the front panel was found when the testing environment temperature was below the glass transition temperature, while the fiber microbuckling of the front panel was also revealed when the testing environment temperature was above the glass transition temperature. The failure load increased with the decreasing of the testing environment temperature at cryogenic temperature. Nevertheless, at elevated temperature, the failure load decreased with the increasing of the testing environment temperature attributing to the weakening of the fiber-matrix interface performances.
