“…However, based on the qualification that a material is qualified as insulating material when its thermal conductivity is less than 0.1 W.m −1 K −1 [19], the slight increase in the thermal conductivity values of the natural fiber reinforced PU foams induced by the addition of the fibers will not affect their application as thermal insulators since their thermal conductivity values were still much smaller than 0.1 W.m −1 K −1 . For comparison, the natural fiber reinforced PU foams in this research has lower or comparable thermal conductivity values with the bio-based thermal insulations as reported in previous researches [12][13][14][15]20].…”

To obtain the energy-saving and environment-friendly lightweight bio-based thermal insulation, polyurethane matrix was incorporated with wood fiber, bamboo fiber, rice husk and liquefied polyol at different percentages (25%, 30%, and 35%). The results revealed that the apparent density for the natural fibers reinforced thermal polyurethane insulation was between 105 kg.m −3 and 178 kg.m −3 by adding 35% of the fibers into the polyurethane matrix. The thermal conductivity of the bio-based thermal insulation ranged from 0.045 to 0.065 W.m −1 K −1 , the addition of the natural fibers increased mechanical strength. The prepared bio-based insulation showed great potential for building thermal insulations with particularly low thermal conductivity (less than 0.065 W.m −1 K −1 ) and self-bearing strength.

In this article, with the aim of promoting sustainability, contributing to the circular economy and the fight against climate change, the production of composite materials from Bio-polyethylene reinforced with corn stover fibers has been studied. The behavior of the materials obtained has been studied experimentally and by mathematical models of micromechanics. The composite materials were produced by extrusion and then injection with from 10 to 50 wt.% of fibers. The creation of a good fiber-matrix interface was studied by the incorporation of coupling agent between (0–8 wt.%). Increase of 131.2% on tensile strength for 40wt.% reinforcement was achieved by adding 6 wt.% of coupling agent. The correct interface was demonstrated by a correlation of 0.99 between the experimental results and the results of the mathematical models used.

“…e annual output of straw around the world has surpassed 2.9 billion tons. Of the 2.9 billion tons, 66% is returned directly to the field or incinerated as living energy, 19% for building materials or vegetable production covering materials, 12% as forage for herbivorous livestock, and 3% as raw materials for handicraft making [1][2][3]. Waste straw is a pollutant and contributor to climate change.…”

Five modification methods are adopted for wheat straw fibers (WSFs). e effects of modification methods on the water absorbency of wheat straw fiber/wheat straw fiber cement-based composite (WSFCC) and the mechanical properties of WSFCC are analyzed. e crystallinity, chemical structure, and micromorphology of WSFs and WSFCC 28-day specimens are characterized by XRD, FTIR, and SEM methods. e results show that the water absorption of WSFs modified with sodium silicate solution, pure acrylic acid emulsion, and silicone waterproof emulsion surface spraying is 10.67%, 5.18%, and 1.05% lower than that of unmodified WSFs, respectively. Alkali modification is the ideal method for improving the strength of WSFCC. Establishing a fitting formula of the relationship between water absorption of WSFs and strength of WSFCC specimens has important theoretical and practical guiding significance for development and application of WSFCC.
