“…In various experiments, it was suggested that chemical reactions between cellulose and a coupling agent led to improvements in the mechanical properties of the composites. In spite of the fact that they are being commonly employed in cellulose modification, convincing evidence was not provided [24].…”

This article considers the modification of cellulose fibres with the use of vinyltrimethoxysilane and maleic anhydride as substances to improve the wettability of the additive in the hydrophobic polymer matrix. The stress is put on the possible ways of modification impact investigation and its description. Effects of the treatment are analysed using Fourier transform infrared spectroscopy, which reveal the presence of new moieties on the cellulose surface, e.g. C=C bonds, C=O and Si-C groups, while dynamic light scattering investigation revealed an increase in the hydrodynamic radii of the molecules which was maximized in the case of modification with the use of maleic anhydride. Furthermore, thermal properties were defined with differential scanning calorimetry and thermogravimetric analysis. Some variations within the process of samples thermal degradation are observed-thermal stability of the specimen modified with maleic anhydride is the highest. The presented approach of combined fibre modification analysis techniques, being a scientific novelty, allows to confirm the treatment impact on cellulose properties at many levels.

A great deal of research has been conducted on composite; one of which is related brake pad in automotive area. Nowadays, the use of material should have a high economic value and eco-friendly properties. Such requirements have encouraged researchers to produce eco-friendly composite material by using natural fibers. Natural fiber is an alternative to produce new brake pad composite that has required mechanical properties and economic value and is ecofriendly. The brake pad composite should have heat resistance value, coefficient of friction, and mechanical strength as needed during the process of braking. In this research, Cantala fibers were chosen as strengthening material of brake pad composite. The volume fractions of Cantala fiber evaluated in this study were 0%, 4%, 8%, and 12%. Other materials used in the composition of brake pad composite production were NBR, fly ash, graphite, CaCO3, phenolic resin, and cashew dust. The specimens were manufactured using the following sequential processes: mixing the ingredients, cold pressing, hot pressing, and finally post curing of the specimens. The result showed an increase in flexural strength of composite friction brake along with the increase in Cantala fiber volume fraction.

“…The fiber surface becomes very clean, flat, dense, and very smooth compared to the untreated one (SS) and alkali treated (SN) surfaces. With better interfaces, it is possible to have compatibility between the bark fiber and polymer matrix [12]. The matrix and the bark fibers will make a good binding , hence the biocomposite can receive the load evenly and provide a very significant impact to increase its tensile strength [13] …”
