Glass fiber-reinforced plastics (GFRPs) have been widely used in marine structures, recently. In this paper, the water absorption and compressive behaviour of pultruded fiber-reinforced plastic pipes (GFRPs) after immersion in Caspian sea water and distilled water for 1, 7, 14, 21, 28, 35, and 40 days is experimentally investigated. In this respect, the specimens are submerged in Caspian seawater and distilled water and then their water absorption rate, length, and their compressive strength were measured every day. The compressive mechanical properties of the specimens in the as-received and water-aged states are obtained using quasi-static compression tests. The amount of water absorption and length change due to immersion in these two cases have also been investigated. After 40 days, the average relative humidity absorption of the samples in Caspian Sea water and distilled water were 2.88% and 2.89%, respectively. It was observed that after immersion in both Caspian Sea water and distilled water, the final compressive strength and absorbed energy of the pultruded pipes increased.

In this study, a series of fire‐retardant vinyl ester resins (VERs) were obtained via the copolymerization of phosphorus–nitrogen‐containing acrylate [1,3,5‐triglycidyl isocyanurate (TGIC)–acrylic acid (AA)–9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO)] and the widely used vinyl ester resin 901 (901‐VER). The influences of the TGIC–AA–DOPO additive amount on 901‐VER were comprehensively evaluated via the measurement of the flame retardancy, thermal performance, and mechanical properties. In the case of 30 and 40% TGIC–AA–DOPO, the thermosets acquired limited oxygen index values of 30.8 and 31.7%, respectively, and reached vertical burning (UL‐94) ratings of V‐1 and V‐0, respectively. In addition, their peak heat‐release rates, average heat‐release rates, total heat release values, average effective heats of combustion, and total smoke productions decreased significantly. These results demonstrated the great progress of 901‐VER in fireproofing performance. More importantly, the flame‐retardant VER thermosets showed good thermal properties and castings, and glass‐fiber‐reinforced composites based on the developed fire‐retardant VERs possessed comparable tensile strength, flexural strength, and better tensile modulus comparing to those based on neat 901‐VER when the TGIC–AA–DOPO amount was no greater than 30%. From an integrated perspective, 901‐VER with 30% TGIC–AA–DOPO was the best desired. The excellent flame retardancy, thermal performance, and mechanical properties promise the as‐obtained VER important applicable values. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

Researchers are continuously working to improve the mechanical characteristics of polymer composites by various approaches such as fiber treatment, filler addition, and others. In this study, mechanical, thermal, and morphological characteristics of composites produced from corn husk waste fibers treated with pumice powder were examined. Corn husk (CHF) and pumice powder (SBA) were mixed in polyester matrix at varied volume fractions of 5: 30, 10:25, 15:20, 20:15, 25:10, and 30:5. The results demonstrate that infusing SBA into the CHF composite enhanced the interfacial adhesion between the CHF and the polyester matrix. As a result, the mechanical and thermal characteristics of the SBA/CHF composites were significantly improved. The composite with 5:30 volume fraction (JPA) exhibited the highest values of tensile strength (18.61 MPa), tensile modulus (3.23 GPa), flexural strength (36.12 MPa), and flexural modulus (3.39 GPa) among all the composites and the polymer matrix which was attributed to the strong SBA/CHF interface bonds in the composites. While the lowest values recorded for the composite specimens were due to a large number of CHF pullouts. Similarly, JPA composites outperformed the other composites in terms of thermal stability. The morphological study indicated that CHF pullout increased with an increased quantity of CHF and dropped as the amount of SBA increased and was distributed equally in the composite. According to the findings, the CHF/SBA composites had better mechanical characteristics than the fiber-glass composites.
