“…Common application topics include cars, airplanes, turbines and mechanical components, biodegradable implants, sports and leisure products and civil engineering applications. In addition, many publications have been published on the topic of recyclability of polymers and composites and degradable materials in recent decades (Czigány et al, 2005;Geier et al, 2022;Mezey and Czigány, 2007;Ronkay et al, 2021). In the civil industry a book was published on structures made entirely of composites (Kollár and Springer, 2003).…”

Throughout history different kinds of composite materials were used for several reasons. Mixing components with different properties the emerging new material can show highly improved material characteristics. This article copes with Advanced Fiber Reinforced Polymer (FRP) as structural material. The trend of the utilization of FRP is continuously increasing not only in transportation or sport industry but also in building industry. Beside the traditionally used base materials new fiber and resin materials are still developing. This paper reviews the brief history of FRP and its often-used base materials. Material properties, advantages and disadvantages, production methods are also discussed.

“…The composite type as a categorical factor with two levels (BFRP and CFRP) and the feed (mm/rev) and cutting speed (m/min) as continuous factors, each on three different levels, were varied according to the experimental table as is shown in Table 2. The levels of these continuous factors (Table 1) were defined based on previous studies and the recommendations of the tool manufacturers [7,23,30,31]. The experimental design is suitable for the application of quadratic models to describe nonlinear influences of process parameters.…”

“…However, their manufacturing is costly, and the life cycle of products made from carbon and glass fibres is relatively short. Their recycling and/or reusing is difficult or often not solvable [6][7][8]. Therefore, researchers developed novel fibrous composites using organic and inorganic reinforcing fibres.…”

Currently, the use of sustainable products and technologies is growing; consequently, mineral-origin basalt fibre-reinforced polymer (BFRP) composites are becoming more popular in industries. Although BFRP parts require mechanical drilling operations for manufacturing holes for assembly, many challenges make the drilling process difficult. Considering that the cutting force is one of the main parameters characterising the drilling process, this study aims to analyse the influence of feed (mm/rev) and cutting speed (m/min) on the thrust force and model the thrust force in the drilling of BFRP composites through response surface methodology (RSM) and advanced statistical modelling methods. In order to determine main and interaction effects and to calculate the regression coefficients and model parameters, mechanical drilling experiments were performed, and the thrust force was recorded. The raw force data were processed using fast Fourier transformation-based low-pass filtering, and then the calculated thrust force parameters were evaluated relative to various feeds and cutting speeds. In addition, results were compared with those of carbon fibre-reinforced polymer composites. The results of the validation experiments show that both RSM and advanced statistical models accurately predict the thrust force in BFRPs of 96.74% and 95.01%, respectively. However, the advanced statistical model can describe not only the maximum values of the force but also its characteristics at a coefficient of determination of 0.68.

“…In contrast, some researchers found no relevant correlation between the feed and the burr characteristics [24][25][26]. Geier et al [27] highlighted that drilling-induced burr formation in chopped CFRP is significantly influenced by fibre cutting angle and the mechanical supporting properties of the laminate.…”

Basalt fibre-reinforced polymer (BFRP) composites probably tend to replace some carbon fibre-reinforced polymer (CFRP) applications due to their excellent specific strengths and sustainability. Despite the published early promising results concerning the material properties of BFRP, their application is not widespread, and their machinability is not supported widely by published experiences. The main aim of the present study is to experimentally investigate the drilling-induced geometrical damages of BFRP and CFRP composites. Drilling experiments were conducted at various feed and cutting speed levels using a solid carbide twist drill. The drilling-induced burr was analysed by a Mitutoyo 361–804 digital microscope, a Mitutoyo SJ400 surface tester recorded the surface roughness, and the microstructure was analysed by a Zeiss Evo MA 10 scanning electron microscope. The measured data were evaluated through digital image processing (DIP), response surface methodology (RSM), and analysis of variances (ANOVA). The experimental results show that drilling-induced burr is more severe and surface roughness is worse in BFRP than in CFRP. The composite type influenced the geometrical damages primarily, followed by the feed in the case of burrs and by the cutting speed in the case of surface roughness. The present experimental study suggests that the drilling of BFRP is even more challenging than drilling CFRP from the point of view of burr formation and micro geometrical properties.
