These environmental conditions cause different damage mechanisms in composites such as pore formation, micro‐cracks, delamination, fiber breakage, fiber/matrix interface separation, plasticization, swelling and surface color change. In this study, wear properties of hybrid glass fiber reinforced polymer composites exposed to various environmental conditions for constant load (60 N), speed (500 rpm) and 2 h were examined comprehensively, depending on material content and environmental conditions. In this experimental study, the service conditions in glass fiber reinforced composites were simulated using different artificial aging environments such as acidic environment, hydrothermal cycle and UV radiation. In addition to the material content, it appears that the environmental conditions to which composites are exposed has a significant effect on friction coefficient. Considering environmental conditions, it is seen that the acid environment and hydrothermal cycle have reduced wear resistance of GFRP composites, while UV radiation improved wear resistance of the composites.

In this article, composite frangible covers were fabricated with short‐cut basalt fiber reinforced epoxy(BF/Epoxy) composites instead of continuous fiber‐reinforced composite materials, reducing the strength redundancy in the local structure of the frangible covers. Tensile tests were firstly conducted on material samples to obtain the stress–strain characteristics of the short‐cut BF/Epoxy composites. The constitutive model and failure criterion of the short‐cut BF/Epoxy composites material were established.

Two frangible covers with different geometric parameter were fabricated and subjected to static bursting strength tests. The influence of structure parameter on the bursting pressure of the frangible cover was investigated in detail. it was found that the bursting pressure of the BF/Epoxy composite fragile cover can be tailored by adjusting the geometry size of the weak zones on surface of the cover.

In this experimental study, the influences of sea water on polylactic acid (PLA) and carbon fiber reinforced polylactic acid (PLA/CF) parts manufactured at different infill rates (20%, 60% and 100%) were investigated. The parts were exposed to sea water for three different periods (1, 5, and 10 days) and subsequently subjected to wear tests. The dimensional accuracy, surface roughness, hardness, water absorption, volume loss, and friction coefficient of parts were measured and calculated. Additionally, the worn surfaces of the parts were investigated using field emission scanning electron microscope (FESEM) images. The findings indicate that PLA and PLA/CF parts can be produced with high dimensional accuracy. Furthermore, it can be reported that the water absorption of PLA/CF parts increased, particularly with an increase in the infill rate, while the volume loss decreased.
