“…As stated in Ref. , all microhole formations increase the contact surface area. The larger area of CFRP surfaces exposed to adhesion (effective surface area) leads to an increase in stress loading points in the joints, thus a higher shear value occurs at all microhole formations .…”

“…, all microhole formations increase the contact surface area. The larger area of CFRP surfaces exposed to adhesion (effective surface area) leads to an increase in stress loading points in the joints, thus a higher shear value occurs at all microhole formations . Such an interlaminar characteristic primarily provides an increase in surface area and enhances mechanical interlocking with microhole formations at CFRP/CFRP joints.…”

There are many different techniques to improve the adhesion between carbon fiber‐reinforced plastics (CFRP) which are used in aircraft primary structures. One of the most common techniques is the specific surface structuring of the joining parts in order to obtain mechanical interlocking. In this study, laser‐induced surface structuring effect on adhesion strength of CFRP/CFRP joints was investigated by single lap shear tests. Microholes were created by CO2 laser with different configurations in x and y axis for the best mechanical interlocking effect on adhesive bonding. The effects of microhole numbers (309, 625, and 914) and microhole formations (triangle, inverted triangle, frame, and box) on the adhesive bonding strength of the CFRP/CFRP joints were determined by using single lap shear tests according to ASTM D5868‐01 standard with 60 kN DARTEC universal test machine. Single lap shear tests showed that microhole structuring has a significant effect on mechanical interlocking for adhesive bonding of CFRP/CFRP joints. Results showed that the shear strength of CFRP/CFRP joints improved at 309 microholes and frame type microhole formations. After mechanical tests, damage mechanisms were observed by using the optical microscope. POLYM. COMPOS., 40:2891–2900, 2019. © 2018 Society of Plastics Engineers

This paper investigates the impact strain response resulting from the numerical Charpy impact test of double-and triplelayered steel-aluminium plate employing time-frequency analysis. The potential of the laminated steel-aluminium plate in weight reduction is evaluated using a single-layered specimen as a reference. The signal processing technique in the time-frequency domain is capable of revealing the behaviour and strength of the laminated plate. The time domain signal from the numerical Charpy impact test is transformed into the frequency domain using the power spectrum density and time-frequency domain by the Hilbert-Huang spectrum. The relationship of strain energy from the finite element method and the power spectrum density showed the R 2 value of 0.8899, indicating that the power spectrum density can be used as an alternative in calculating the strain energy. In this study, the frequency distribution in the power spectrum density was compared with the Hilbert-Huang spectrum. The triple-layered specimen was found to show better performance with 23% higher maximum strain and 11% more strain energy to fracture, compared to the double-layered specimen. Therefore, the analysis in both frequency and time-frequency domains provide a better understanding of the impact behaviour of the double-and triple-layered plate.
