Introducing lignocellulosic fibers as the matrix reinforcement in composites is an opportunity for weight reduction and also use of by-products biomass waste from other systems, such agriculture textiles. In case nautical applications, biofouling, meaning damage during service by marine organisms, represents a significant issue. To address this problem, number measures can be taken: these include introduction various types fillers, mainly mineral, composites, tailored treatment fibers, hybrid approaches, including different modifications, or fiber grafting. This review reports state art studies carried out to elucidate performance natural hybrids regards water absorption more specifically exposure seawater prolonged time so simulate conditions. The perspectives on (NFCs) aquatic environments will discussed with respect possible onset degradation biofouling.

Waste stone sludge generated by the extractive industry has traditionally posed significant disposal challenges. This study redefines as a valuable raw material incorporating it into polylactic acid (PLA) to create sustainable composite materials. Pellets and filaments composed of up 50% weight limestone powder PLA were successfully produced using melt blending in twin-screw extruder. Scanning electron microscopy (SEM), X-ray fluorescence (XRF), diffraction (XRD) analyses revealed uniform distribution particles within matrix confirmed chemical structural compatibility components. Thermogravimetric analysis (TGA) showed that composites retained thermal stability, while mechanical testing demonstrated enhancements stiffness, with an increase elastic modulus for containing powder. The flow rate (MFR) decreases increasing filler content. brittleness also increased, reducing impact resistance. Mechanical tests performed on injected 3D-printed specimens. filament was used 3D printing, small XYZ calibration cube.

The growing demand for complex structures, energy absorption, and mechanically strong materials has led to the exploration of innovative composites. This study focuses on manufacture, characterization, evaluation PLA+ reinforced with woven glass fiber. Using Fused Filament Fabrication (FFF) 3D Printer technology, effects adding fiber were examined through a tensile test Digital Image Correlation (DIC)-induced, flexural, Charpy impact resistance, Shore D hardness, Differential Scanning Calorimetry (DSC) thermal tester, SEM morphological tests. Results showed that four layers significantly improved mechanical properties: strength increased by 85% 95.44 MPa, flexural 13% 91.51 resistance 450% 15.12 kJ/m2. However, reduction in hardness was noted due chemical interactions. These findings suggest potential applications composites high-strength products vehicle bumpers automotive industry shin pads sports industry.
