Special Issue Information

Dear Colleagues,

Polymer–matrix composites with carbon fiber reinforcements are finding ever increasing applications in aerospace, mechanical, transportation, green energy, and civil infrastructure engineering fields. Fibers at the nano-level and the micro-level are used in discontinuous and continuous reinforcement forms to achieve superior mechanical properties, durability, and high performance. The present Special Issue focuses on recent developments in the characterization of nano-, micro-, meso-, and macro-level mechanical properties of such composites using experimental, analytical, and computational approaches and techniques. It also focuses on the novel, innovative applications of such composites in the abovementioned engineering areas and other similar areas. Research works on tensile, compressive, shear, fracture, fatigue, creep, impact, and damping properties of such composites, as well as on the durability and degradation due to temperature and moisture, will be covered in this Special Issue. Works on nanocomposites involving atomistic, molecular, and continuum mechanics computational modeling, experimental investigations, and hybrid approaches will also be covered. Static and dynamic applications for machine tools, machine elements, mechanical structures, aerospace structures, automobile structures and components, naval vessels, helicopter blades and rotors, infrastructure, rotating machinery, and similar practical components and structures will be of interest to the present Special Issue.

Abrasive suspension jet (ASJ), an accurate cold-cutting technology, can address traditional processing issues relating to carbon-fiber-reinforced plastics (CFRPs) like tool wear, interlayer delamination, large heat-affected zone, and low surface roughness. This study employed the use of an ASJ to cut CFRPs and an ultra-depth optical microscope to scan the cut surface to analyze interlayer delamination, surface roughness, kerf taper, and shoulder damage. Regression analysis was conducted to establish a prediction model for cutting quality based on surface roughness, kerf taper, and shoulder damage. Various types of CFRP cutting quality were analyzed using jet parameters. It was found that the use of ASJ to process CFRP results in the following defects: The range of surface roughness variation is from 0.112 μm to 0.144 μm. Surface roughness is most influenced by stand-off distance, followed by traverse speed and jet pressure. The range of kerf taper variation is from 4.737° to 10.1°. Kerf taper is most influenced by stand-off distance, followed by jet pressure and traverse speed. The range of shoulder damage variation is from 3.384 μm2 to 10 μm2. Shoulder damage is most influenced by jet pressure, followed by traverse speed and stand-off distance. A prediction model for cutting quality was developed based on surface roughness, kerf taper, and shoulder damage, providing data support for ASJ cutting of CFRPs. The optimal parameter combination is a stand-off distance of 1 mm, a jet pressure of 30 MPa, and a traverse speed of 30 mm/min. Full article
