“…However, thanks to this type of protocol, the BS_2 and BS_4 systems obtain a thicker skin-deep coating which guarantees higher impact resistance [ 22 , 23 ]. It is worth noting that, in the case of the coated materials, the first significant load drop occurs in correspondence to the maximum load, while in the case of neat BS laminates, several load drops, denoting delamination initiation and propagation, are observed.…”

Hydrophobic surfaces are highly desired for several applications due to their exceptional properties such as self-cleaning, anti-icing, anti-friction and others. Such surfaces can be prepared via numerous methods including plasma technology, a dry technique with low environmental impact. In this paper, the effect of a one-step sulfur hexafluoride (SF6) plasma treatment upon the low velocity impact behavior of basalt/epoxy composites has been investigated by using several characterization techniques. A capacitive coupled radiofrequency plasma system was used for the plasma surface treatment of basalt/epoxy composites, and suitable surface treatment conditions were experimentally investigated with respect to gas flow rate, chamber pressure, power intensity, and surface treatment time by measuring the water droplet contact angle of treated specimens. The contact angle measurements showed that treating with SF6 plasma would increase the hydrophobicity of basalt/epoxy composites; moreover, the impact results obtained on reinforced epoxy basalt fiber showed damage in a confined area and higher impact resistance for plasma-treated basalt systems.

“…Take the square box area with a side length of 0.01d f as the benchmark, that is, δ S � (0.01d f ) 2 , and record the number of boxes, M 2 (δ S ). e area of the white part, S f , can be obtained through equation (2). Besides, start measuring with δ L � 0.01d f as the side length of the box and record the number of boxes M 1 (δ L ).…”

“…First, the performance and mechanism of BFRP materials are analyzed, aimed at improving their mechanical properties and durability and exploring their internal mechanism. For example, [1][2][3][4] used different methods to treat and modify the fiber surface and studied the influence of fiber surface modification on the tensile properties of BFRP. e results showed that the mechanical parameters, such as tensile strength and elastic modulus, were significantly improved after the modification.…”

To explore the clustering phenomenon of discontinuous fibers in composite materials, this paper deduces the fiber uniform distribution coefficient and analytical expressions of fiber clustering content based on fractal theory and establishes a tensile strength prediction model of fiber/epoxy resin composite materials containing cluster fibers. With basalt fiber/epoxy resin composites (BFRP) as an example, this paper analyzes the tensile strength law of BFRP under fiber clustering effect. The results show that when the fiber volume fraction is constant, the tensile strength of the composite in the presence of agglomerated fibers is only related to the fractal dimension of the circumference and cross-sectional area of the inner fiber agglomerate. The calculated value of the composite tensile strength based on fractal theory is lower than the experimental value, but closer to the experimental value than the approximate method. The research conclusions can provide theoretical support for strength prediction of fiber/epoxy resin composites.
