“…In the construction of transport vehicles, the range of composite material applications has been continuously increasing. These materials are used for selected elements, for example, vehicle bodyworks, as well as for whole constructions, for example, in the spacecrafts, aircrafts, and sea transport . Their applicability in the transport sector is justified by their low dead weight, combined with their high strength and elasticity properties as well as their resistance to atmospheric factors.…”

The aim of the work is to evaluate the effectiveness of analysis of a failure progress of the glass fiber reinforced polymer laminate (classic and 3D), during static bending, with the use of high frequency vibration analysis (the order of kHz). During the tests, the instantaneous velocity of the samples' vibrations was recorded. The 3D laminate showed a more favorable course of failure (mostly fiber fracture) than the classic laminate (mostly delamination), but only in the direction transverse to the translaminar interweave strands. In the direction parallel to the interweave, it was also characterized mainly by delamination. It was stated that the vibration measurements significantly broaden and supplement the characteristics of bending, by way of revealing the local degradation changes in the examined material, especially before the initiation of the main stage of failure. The work also describes the frequency bands in which the symptoms of the occurring failures of particular laminate components were observed and where the values of the basic point parameters were estimated, which points to the occurrence of structure failure. The obtained results confirm the effectiveness of the vibration analysis as a tool for the evaluation of the course of composite material failure under static loads. POLYM.

This study investigates the performance of sandwich composites composed of polyvinyl chloride cores reinforced with E-glass fibers and bonded with isophthalic and orthophthalic polyester skins. The aim is to comparatively assess the mechanical and morphological characteristics of these composite structures. The comparative analysis also included variations in the skin thickness of the sandwich composite. Mechanical tests such as compressive, impact, and hardness were carried out. Moreover, fracture tests specifically focusing on single-edge notched beam fracture (mode I) were conducted under different temperature conditions, low (−10 °C), ambient (25 °C), and high (100 °C) temperatures. Comparative analysis of the mechanical properties indicated that the isophthalic-based sandwich composites exhibited superior mechanical characteristics when compared to their orthophthalic counterparts. Fracture properties of both types of sandwich composites demonstrated higher values at lower temperatures, followed by room temperature, and then high temperatures. In both types of sandwich composites, using two layers of E-glass on both sides of the polyvinyl chloride foam resulted in superior properties. This improvement can be attributed to the increased skin thickness. The interfacial properties were identified using Fourier transform infrared spectroscopy and scanning electron microscopy, revealing distinct spectroscopic features such as CH-stretching, C–O–C, CH bend, CN stretching, and NH stretching. Examination of the fractured surfaces through scanning electron microscopy revealed distinct features such as crushed fiber, fiber pull-out, honeycomb, riverline patterns, matrix-fiber delamination, and debonding, providing valuable insights into the composite's structural integrity.
