“…It has been reported that in particleboards produced by adding 10, 20, and 30% stone wool using urea formaldehyde glue, the mineral wool reduced the bending strength by up to 65% and the internal bond strength by up to 71%, due to the reduction of the cohesion force inside the board (Mamiński et al 2011;Yap et al 2021). Cong et al (2021) added a layer of mineral wool and glass wool to epoxy-based carbon fiber polymeric laminates and investigated their combustion and mechanical properties. Results indicated that the addition of the flame-retardant layers reduced the bending strength from 836.4 to 767.0 MPa.…”

Wood fiberboards are used extensively, mainly in the fields of furniture production, interior fittings, construction, etc. Mineral stone wool materials are used for heat and sound insulation in the construction industry. This study aimed to produce a new hybrid-based composite material by mixing fibers obtained from wood and mineral stone wool. For this purpose, hybrid fiberboards with 50, 40, 30, and 20% stone wool addition and a fiberboard group consisting of 100% pine and beech fibers (control sample) were produced in a hot press using thermoset-based urea formaldehyde and phenol formaldehyde resins. Statistical comparisons of the results were made for values of density, thickness swelling, and water absorption extents after 24 h immersion, bending strength and modulus of elasticity in bending, tensile strength perpendicular to the board surface (internal bond strength), and time to ignition (TTI) analysis. Additionally, percentage of mass loss (PML), average heat release rate (A-HRR), average effective heat of combustion (A-EHC), and mass loss rate (MLR) were studied. The results showed that as the stone wool content in the produced boards increased, the mechanical properties and thickness swelling decreased. The combustion results showed that the combustion resistance of the boards increased with increasing stone wool ratio.

“…Some of the systems reported in Table 4 used epoxy resins or magnesium hydroxide particles for the preparation of flame-retardant coatings. Cong et al [50] prepared hybrid composites of bio-based thin-ply carbon fiber prepreg and flame-retardant mats (E20MI). The inclusion of FR mats in the thin-ply bio-based prepreg revealed that the FR mat location can increase both the fire protection results and the mechanical properties.…”

Wood and wood-based products are extensively used in the building sector due to their interesting combination of properties. Fire safety and fire spread, however, are of utmost concern for the protection of buildings. Therefore, in timber structures, wood must be treated with fire-retardant materials in order to improve its reaction to fire. This article highlights the flame retardancy of novel hybrid organic–inorganic halogen-free coatings applied on plywood substrates. For this purpose, either a huntite-rich mineral (H5) or its modified nano-Mg (OH)2 type form (H5-m), acting as an inorganic (nano) filler, was functionalized with reactive oligomers (ROs) and incorporated into a waterborne polymeric matrix. A water-soluble polymer (P (SSNa-co-GMAx)), combining its hydrophilic nature with functional epoxide groups, was used as the reactive oligomer in order to enhance the compatibility between the filler and the matrix. Among various coating compositions, the system composed of 13% polymeric matrix, 73% H5 and 14% ROs, which provided the best coating quality and flame retardancy, was selected for the coating of plywood on a larger scale in one or two layers. The results indicated that the novel plywood coating systems with the addition of ecological coating formulations (WF-13, WF-14 and WF-15), prepared at two layers, reached Euroclass B according to EN13501-1, which is the best possible for fire systems applied to wood.

“…For instance, Li et al 15 designed an intumescent flame-retardant mat for CF-reinforced composites and reported a reduction in the heat release rate with side effects on mechanical properties and extra smoke emission. Cong et al 16 confirmed this issue and proposed that the poor structural stability of the surface protection layer leads to the deterioration of the mechanical properties of the composites. Nonetheless, it remains unclear what strategy to use to balance between fire resistance and structural performance for high-performance fiber-reinforced composites.…”

The fire-retardant properties of high-performance fiber-reinforced composites are the crucial benchmark for composite structure stability. However, in the current flame-retardant solution for composites it is difficult to reach the balance between fire resistance and structural performance due to the deteriorating composite interface. In this work, the carbon fiber-reinforced composite was covered with functional glass fiber layers, in which the glass fiber veil had been treated with flame-retardant agents and silicone-modified waterborne polyurethane, in order to be endowed with flame-retardant capability and structure toughness. As such, a significant improvement in the flame retardancy and mechanical structure of the composites could be observed. When compared with the control, the total heat release and total smoke release for composites with 8% silicone-modified waterborne polyurethane treatment could be decreased by 18.5% and 18.1%, while the tensile and flexural strength were significantly increased by 47.3% and 62.2%, respectively. This well-balanced performance is attributable to the structure design with a toughened glass fiber veil to protect the composite surfaces from fire combustion and structure failure. Therefore, this flame-retardant structure design provides a new strategy to achieve high-performance composites with prospective applications for aircraft and aerospace.
