“…It is observed that the tensile properties increase with γ-pretreatment up to a certain limit (5 kGy) and then decrease due to two opposing phenomena, namely: photo cross-linking and photodegradation that take place simultaneously under γ-radiation. 43 At lower doses, free radicals are stabilized by a combination reaction, and as a result, photo cross-linking occurs. The higher the number of active sites generated on the polymeric substrate, the greater the grafting efficiency.…”

The fiber architecture can significantly influence the rate of impregnation of a resin in making composites and the load-bearing ability of individual fibers on testing of the loading directions. Moreover, achieving the maximum mechanical performance of a natural fiber composite selection of yarn liner density and optimization of fabric structure and further modification of the composites remains a great challenge for the composite research community. In this study, a number of jute-based woven derivatives (plain, 2/1 twill, 3/1 twill, zigzag based on a 2/2 twill, and diamond based on a 2/2 twill) have been constructed from similar linear densities of yarn. The effect of the fabric architecture and further modification of optimized composites by applying γ-radiation is also explained in this study. The experimental results show a 54% increase in tensile strength, a 75% increase in tensile modulus, a 69% increase in flexural strength, a 124% increase in flexural modulus, and 64% increase in impact strength of twill (3/1) structured jute fiber polyester composites in comparison to other plain and twill structured composites. A further mechanical improvement of around 20–30% is possible for the optimized twill structured composites by applying γ-radiation on the composites. An FTIR, TGA, and SEM study confirms the chemical, thermal, and fractographic changes after applying the modification of composites.

“…It can improve the reinforcing fiber's compatibility with the polymer matrix [ 22 ]. As a result, the physico-mechanical properties (tensile strength and modulus, bending or flexural strength and modulus, impact strength, density, dimensional stability, and so on) and thermo-chemical properties (chain scission as well as cross-linking within matrix and reinforcement, interfacial polarisation and orientation, thermal stability, hydrophobicity, glass transition temperature, and so on) of natural fibre reinforced polymer composites increased up to a specific dose [ 2 , 11 , 23 ]. This method is less expensive, easier to use, and takes less time to expose than x-rays or ultraviolet radiation [ 22 , 23 , 24 , 25 ].…”

“…In recent years, with the expanding pineapple processing industry, the resulting pineapple waste has gradually increased. Currently, the utilization of pineapple waste in China is still low, and some areas (such as Yunnan and Fujian) use none of it (Li et al 2013b;Rahman et al 2019;Zhu 2019). The efficient and reasonable development and utilization of pineapple waste will not only solve the problem of resource waste, but also contribute to solving the problem of environmental pollution, thereby increasing the economic benefits of the pineapple industry.…”

To improve the utilization rate of pineapple leaf and crop straw, and provide technical support for making biodegradable fiber mulch paper through organic cultivation, the process and properties of the degradable fiber mulch paper made from pineapple leaf and rice straw were studied. The degradable fiber mulch paper was prepared as a hybrid composite in which pineapple leaf fiber and rice straw fiber were used as raw materials, and environmentally friendly agents were added. A four-factor five-level quadratic orthogonal rotation central composite design of the response surface method was employed. The beating degree of pineapple leaf fiber, basis weight, addition ratio of pineapple leaf fiber, and wet strength agent content were process parameters; dry tension strength, wet tension strength, and bursting strength were objective functions. The optimal technology parameters of pineapple leaf and rice straw fiber mulch paper were 70 to 90 g/m2 basis weight of pineapple leaf fiber, 17% to 25% addition ratio of pineapple leaf fiber, 55 °SR beating degree, and 1.5% wet strength agent content. According to the tensile strength and bursting strength standards, the degradable fiber mulch paper made from pineapple leaf and rice straw was feasible. The results provide theoretical basis and technical support to use pineapple leaves and rice straw to make degradable mulch paper.
