“…Acoustic properties of materials, including composites, are widely studied. [10][11][12][13][14] The acoustic parameters in solids are determined by their elastic behavior. The importance of acoustic analysis arises from the fact that often the same microstructural characteristics control both acoustic parameters and mechanical properties of the material.…”

The effect of N 0 -(o-phenylene)dimalemide and 2,2 0 dithiobis(benzothiazole) on the speed of sound, sound attenuation and loss factor, 3-D microstructure, fiber dispersion, and morphology of wood pulp-reinforced PLA composites produced by hot press was investigated. Analysis of the chemical composition and fiber length of the wood pulp fibers provided information about the mechanism of adhesion and crystallinity of the modified composites. It was found that the modified composites have quite similar sound attenuation values, whereas the 3-D tomography analysis suggests the creation of a closely compact, cross-linked microstructure with improved fiber dispersion at higher processing temperature. The occurrence of a uniform, single-phase morphology suggests good compatibility between N 0 -(o-phenylene)-dimalemide and 2,2 0 dithiobis(benzothiazole) to PLA. Fourier transform-infrared (FT-IR) spectrometry suggests the creation of a new bond involving scission of the N 0 -(o-phenylene)dimalemide molecule to PLA and/or wood pulp. XRD analysis showed that the largest increase in the crystallinity occurred in the modified PLA blends.

“…The bond strength between different materials can be evaluated by x-ray [4], Lamb wave [5] and ultrasonic [6][7][8][9]. Jasiūnienė [4] used x -ray to scan the composite fault, To evaluate the effect of the adhesive layer pores on the properties of the adhesive layer, but this method requires the destructive testing of the sample; Ren et al [5] used Lamb wave to study the metal bonding layer.…”

In the field of nondestructive testing (NDT), the bond defect detection of ultra-thin metal and silica gel is a difficult problem. In this study, the ultrasonic resonance method was used to evaluate the bonding quality of ul-thin metal. Study three different bond states of ultra-thin nickel sheet and silicon film composite, nickel and silica gel bond state, the absorption of ultrasonic differences, with the use of high-frequency ultrasound in ultra-thin nickel slice of resonance, through the resonance signal analysis of ultra-thin nickel sheet and silicon film combination, the bonding coefficient of the bond state between ultra-thin nickel sheet and silica gel. Through experimental comparison, the results show that the attenuation of ultrasonic signal in the nickel sheet and silicon film with different bonding states characterize the bonding state of ultra-thin nickel sheet and silicon film by the bonding coefficient, the bonding coefficient of good parts, weak adhesive parts and debonded parts is reduced successively. By setting an appropriate determination threshold value, the bonding state between the ultra-thin nickel sheet and the silicon film can be accurately determined according to the bonding coefficient obtained by detection.
