“…It entails manually inserting fibers into a mold, followed by applying resin to help the fibers join. This approach is well suited for small-scale production because it is simple and economical [121,143,144]. Compression molding is another process used in the production of NFRCs.…”

“…This information helps in identifying areas of high stress or strain that could lead to failure or discomfort, prompting design optimization to mitigate these concerns. FEA has been extensively used in the design and evaluation of NFRCs [120,143,144,162,[168][169][170]. For instance, it has been employed to evaluate the impact of different fiber orientations and laminate configurations on the mechanical performance of devices.…”

“…From the analysis of the pores, it was already confirmed that the fibers were oriented in the direction of the rotation of the collector; therefore, when the load is applied in that direction, the fibers can transfer more effectively the stress along the material, increasing its resistance. 57,58 Finally, the polymer composition did not seem to affect much their mechanical performance; only a slight increase in the tensile strength in the case of PEO/PCL materials with respect to the neat PEO was observed. This result makes sense taking into account that the mechanical properties of PEO, E ∼ 70 MPa and σ max ∼ 0.7 MPa, 59 are poorer than those of the PCL, E ∼ 300 MPa and σ max ∼ 20 MPa.…”

In the present work, fibrous materials based on poly(ethylene oxide) (PEO), poly-ε-caprolactone (PCL), and a mixture of them (PEO/PCL) have been prepared by solution blow spinning (SBS). The rotation speed of the collector of the SBS device (500, 1000, 1500, 2000, 2500, and 3000 rpm) has been chosen as the processing variable to modify the materials’ morphologies. The structures of the polymer systems have been evaluated by attenuated total reflectance Fourier transformed infrared spectroscopy and X-ray diffraction, and the morphologies have been inspected by field emission scanning electron microscopy, while thermal and mechanical behaviors have been studied by differential scanning calorimetry and tensile tests, respectively. Dissolution in water has been monitored by optical microscopy and video recording. As a proof of concept, the capacities of the systems under study to release a model drug have been tested by loading the materials with silver(I) sulfadiazine (SSD) and then immersing them in a buffer solution and monitoring the process through the intrinsic fluorescence of SSD. Our results indicate that there are no changes at the molecular level, but there is a change in the morphology of the material as a function of the rotation speed of the collector. These morphological variations, together with the composition of the system, affect the mechanical behavior of the material, the dissolution process in water, and the drug release. These factors are relevant if the blow spun material is intended for biomedical applications in which an active agent has to be released in a controlled manner.

“…Composite materials have found an increase in applications in many engineering applications in recent years, and subsequently, the need for accurate composite machining has grown enormously. [3][4][5][6] The thermoset epoxy resin is widely used as a matrix in many fiber-reinforced composite materials. Epoxy composites play a vital role [7][8][9] in structural application because they provide balanced chemical and mechanical properties.…”

This research focuses on the mechanical and thermal characterization of vacuum-assisted resin transfer moulded epoxy-based glass fiber-reinforced composites. Mechanical testing, including tensile and flexural tests, and heat dissipation analysis under the applied load, are used to analyse the prepared specimens. A thermal imaging camera is used to measure temperature changes to determine energy release, which significantly impacts the composite's surface energy in terms of heat. Differential scanning calorimetry and thermogravimetric analysis were used to examine the thermal stability and decomposition properties. It is noted that the glass transition temperature is 371.15°C, and the decomposition temperature is 380.90°C. Under a scanning electron microscope, the fractured specimens are examined for failure analysis. According to these results, the manufactured composite is suitable for various structural engineering applications.
