چکیده
Carbon fiber-reinforced plastic/titanium alloy (CFRP/Ti) stacks are widely used in the aerospace field based on their high strength to weight ratio and heat resistance. High-quality bolt hole assembly is critical for safety of industry. Reaming a crucial process precision machining extensively improve quality holes. Due different properties material, with conventional reaming (CR) presents some challenges, such as tolerance variations across group difficulty controlling thrust. In this paper, ultrasonic vibration applied process. A geometrical model (UVR) was established analyze its kinematic law. UVR experiments CFRP/Ti were carried out study influence amplitudes thrust tool speed thrust, dimensional accuracy, surface roughness under optimal amplitude. The average forces decreased by over 57% (Ti) 40% (CFRP), respectively, compared CR. CFRP reduced 20% 28% titanium alloys. topography holes significantly improved UVR. This work guides manufacture high-quality stacks.

Experimental Investigation of Behavior of Glass Fiber Reinforced Concrete (GFRC)
The paper presents the results of casting and testing of 264 GFRC specimens. The glass fibers were 25 mm long, with the aspect ratio (L/D) ranging between 1250 and 3570. The parameters studied were the ratio (by weight) of fibers to cement, i.e. F/C=0%, 1.5%, 3%, and 4.5%, and the ratio of coarse to fine aggregates (gravel to sand), i.e. G/S=1.1, 0.7 and 0.2. In total, 12 mix designs were selec...

متن کاملEffect of Fiber Surface Treatment on Wear Characteristics of Carbon Fiber Reinforced Polyamide 6 Composites
Ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(PAN)-based carbon fiber. The surface characteristics of carbon fibers were characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber reinforced polyamide 6 (CF/PA6) composites were investigated by means of the single fiber pull-out tests. As a result...
