Fiber-reinforced polymer composites are exposed to severe environmental conditions throughout their intended lifespan. It is essential investigate how they age when cold and hot water increase the durability of fiber-reinforced composites. This work uses a hand lay-up process create with different weight percentages glass fiber, nanoclay, epoxy. ASTM guidelines followed for performing tensile flexural tests. The input parameters, varying wt.% fiber continuous, aging condition deemed categorical factor. mechanical properties considered as response variables (output). optimized using Response Surface Methodology (RSM), while Artificial Neural Networks (ANNs) provide reliable predictive model high correlation coefficients. findings demonstrate that ANNs outperform RSM in strength prediction, whereas offers greater accuracy modeling. SEM analysis fracture surfaces reveals causes specimen failure under load, distinct differences between dry, cold, boiling water-soaked specimens.

This study investigates the mechanical performance of basalt fiber-reinforced polymer (BFRP) laminates as a suitable alternative to conventional glass composites for marine applications. The were produced by varying main process parameters: fiber type was either or basalt; resin material polyester vinylester; orientation in selected layers set 0°/90°, ±45° rotating woven fabrics during lay-up, and finally manufacturing technique hand lay-up vacuum infusion. Three-point flexural tests with different spans conducted evaluate behavior fracture mechanisms. best-performing configuration, based on fibers infusion, achieved maximum strength about 500 MPa, while basalt-based reached values up 400 MPa. Basalt exhibited highest modulus, exceeding 24 GPa. An increase span length from 120 mm 220 resulted reduction approximately 6–18% depending laminate highlighting influence loading conditions behavior. effect processes also evaluated using an analysis variance. showed that type, method, significantly influenced performance.
