“…The nucleation effect of natural fibres has been increasingly described in the literature [25]. Similar relations have been reported in the work of Ying, which confirmed that the introduction of BF can promote the cold crystallisation of the matrix PLA [26]. The addition of fibres also affected the increase of the degree of crystallinity (X c ) of PLA composites, which was confirmed by strength tests-with the increase in crystallinity, the stiffness of materials increased.…”

In this study, biodegradable biocomposites based on polylactide with basalt fibres (BFs) or wood fibres (WFs) of 7.5 or 15 wt% were prepared by injection moulding. Various tests, including tensile test, bending test and impact test, were carried out to investigate the mechanical properties of the composites. Additionally, the samples were tested at different temperatures. Depending on the type of fibre, differences were noted in their mechanical properties; the addition of WF caused a decrease in strength and the higher the fibre content, the higher the decrease was noted from 18% up 25% in the case of tensile strength. However, the Young modulus was improved by 45% for composites with 15 wt% of WF. The addition of BF improved all the properties, especially Young modulus was improved by over 45%. Despite the low strength observed in neat polylactide at high temperatures-394 MPa, the addition of WF or BF improved the flexural strength more than twofold up to 1684 MPa (PLA/15BF). Moreover, the addition of natural fibres caused an increase in dimensional stability as shown by the decrease of the coefficient of thermal expansion which dropped over 50% for composites with 15 wt% of BF, which significantly expands the areas of use of materials. After 4 weeks of biodegradation, only a slight decrease approximately 5% was observed in the mechanical properties together with an increase in crystallinity. Overall, the results confirm that the prepared composites can be successfully used in engineering applications with long-term operation.

“…Both silane and NaOH treatment were reported to improve the thermal stability of the resulting composites, but silane treated hemp-HDPE composites exhibited superior thermal stability due to a better interphase. As regards basalt fibres, several works have confirmed their potentialities to replace glass fibres [13][14][15][16][17][18][19], but from these studies clearly emerged the need to increase, also for basalt fibres, the interfacial adhesion with the polymeric matrix. In the present study the effect of a compatibilising agent, namely maleic anhydride grafted high density polyethylene (MAPE), on the mechanical and thermal properties of hemp, basalt and their hybrid composites has been studied.…”

Despite the advantages offered by natural fibre-based thermoplastic composites in terms of environmental impact and cost, their mechanical performance is generally lower than that of synthetic counterparts. Hybridisation with mineral fibres (basalt) can broaden the industrial applications of natural fibre reinforced composites. The present study focused on the performance of injection-moulded short basalt fibre, hemp fibre and hemp/basalt fibre hybrid high density polyethylene (HDPE) composites. Effects of a maleated coupling agent on the thermal and mechanical properties of the resulting composites were evaluated as a function of the fibre mass fraction. Hybridisation of hemp fibres with basalt fibres was found to significantly increase the mechanical properties and the crystallinity of hemp-fibre reinforced composites thus suggesting that short hemp/basalt fibre hybrid HDPE composites are promising candidates for semi-structural applications. Additionally, a sizing removal procedure mimicking the conditions experienced in an end-of-life composite thermal recycling process was defined and discussed in terms of residual mechanical properties of basalt/HDPE composites.

“…In fact, BFs could be a good option for producing polymer composites possessing distinguishable properties . BFs, which chemically speaking, have much similar composition as the glass fibers such as SiO 2 , Al 2 O 3 , CaO, P 2 O 5 , Cr 2 O 3 , Fe 2 O 3 , MgO, TiO 2 , K 2 O, Na 2 O, and FeO, possess interesting properties including high melting temperatures (range between 1350 and 1700 °C), high modulus elasticity, excellent heat resistance, and outstanding vibration isolators . Besides those promising properties, BFs are relatively cheaper than carbon fibers, non‐toxic and natural, which undeniably make them a good alternative to reinforce polymer materials.…”

This present article investigates the effect of silane-treated basalt fibers (TBFs) on the morphological, mechanical and thermal properties of cyanate ester/benzoxazine (CE/BOZ) resin composites. The characterization was made using a scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), flexural test, impact strength (IS) test, microhardness test, dynamic scanning calorimetry, and thermogravimetric analysis. The mechanical test results inferred the distinctive improvements in the values of the flexural strength and modulus, IS, and microhardness of the CE/BOZ composites. The thermal stabilities in terms of the T g , T 5% , T 10% , and T HRI were appreciably improved and were higher than those of the pure CE/BOZ resin. Data from the SEM and FTIR tests ascertained the good dispersion and adhesion between the TBFs and the resin matrix, which might be behind the significant enhancement in the ultimate performances of the composites, with respect to the distinguished properties of BFs.
