The authors declare no conflict of interest. Various continuous fabrics (braided, woven or stitched and knitted), strand mats and bulked or texturized rovings are used to obtain high strength in the transverse direction. Low or high temperatures, water immersion, humidity, ultraviolet (UV) exposure, alkaline environment, saltwater, etc., can identify the main environmental conditions. Moreover, the exact time (from tens of minutes to hours) and temperature (up to 180 C) for curing mostly depend on the type of material that is autoclaved. Due to the fiberglass being inside the concrete and the addition of additives and acrylic co-polymer the price is steeper. Leonard, L.W.H.

Anisotropic strain rate effects on the fibre-matrix interface decohesion in sheet moulding compound composites. Nowadays, PAN fiber, viscose rayon, mesophase pitch or petroleum residues (in protected atmosphere) are most widely popular for the manufacture of CFs. PT technology produces FRP composites typically consisting of a thermoplastic or thermoset polymer, reinforced with carbon, glass, aramid fibers or combinations thereof. The heat autoclave design considerations are not simple because both radiative and convective heat transfer mechanisms occur. In this regard, an efficient automation of the process would represent a significant increase both in the quality of the FRP products and in their quantity.

Moreover, future research directions may be geared towards recycling existing composites into high-value alternative products. Moreover, due to the low-viscosity fluid and the long reinforcement fibers used in processing, the RTM is particularly suitable for manufacturing low-weight and high-strength FRP composite parts with complex 3D shapes and low resultant voids. Unlike other materials such as sprayed foam insulation or foam board, wet fibreglass insulation loses all R-value and has almost no insulating properties until it dries out. It may seem that fiberglass reinforcement is expensive while other traditional steel reinforcement is relatively inexpensive. Naked alpaca wool works better with silicone elastomers.

Low weight with high mechanical strength, resistance to chemicals, corrosion and UV radiation are just some of its properties. Another challenge in the RTM process is related to the in situ modeling of polymerization. Therefore, an optimal ecological solution, to these growing problems, would involve the integration of the recycled CFs into a high-value alternative product. Sulphate attacks, abrasions and steel corrosions are major threats to the sustainability of the marine structures. Zhao, J. Xian, G.; Guo, R.; Li, C.; Hong, B.
