“…The composite products adopt 40 symmetrical layers, the layer ratio is 30/40/30, the thickness of each layer is 0.15 mm, the thickness of the composite material layer is 6 mm, and the layering sequence is [AE45/0/ 90/0]. [27] The tubular elements were made of formed carbon fiber pipes, and the process route was made by cutting the carbon fiber pipe, opening the connection hole of the embedded part, smearing the embedded parts and the carbon fiber pipes, connecting them with bolts, and curing and forming them with a lap bar, as shown in Figure 16. The lap bar arm adopts the mold forming and autoclave preparation process.…”

“…Microwave processing offers an intriguing prospect for more efficient and productive manufacturing in a variety of industries. 27 Microwave-assisted processing of polymer-based composite is a new and emerging field with growing interest across various sectors such as aerospace, 28,29 automobile, 30 and so forth. Singh and Zafar reported curing of polypropylene and polyethylenebased composites in 1500 and 1200 s, respectively at a power of 900 W. A constant pressure of 0.20 MPa was used in both situations to prevent the development of voids during the molding.…”

Natural fiber‐reinforced composites are gaining significant popularity for their biodegradability and eco‐friendliness. Fiber modifications and hybridization have been used to address issues like hydrophilicity and fiber inhomogeneity. However, efficient manufacturing is still a challenge for natural fiber‐reinforced polymer composites. The present study explores the potential of microwave processing of hybrid laminates composed of sisal and jute fibers. The laminates, consisting of linear low‐density polyethylene (LLDPE) as matrix and sisal and jute as reinforcement materials were subjected to microwave processing at specific power, time, frequency, and loads. Four types of laminates with different stacking sequences: sisal‐sisal‐sisal (SSS), sisal‐jute‐sisal (SJS), jute‐sisal‐jute (JSJ), and jute‐jute‐jute (JJJ) were developed. The developed composites showed ~3% void content, with the SJS and JSJ composite having the least and highest void content, respectively. The SJS composite showed the highest tensile and flexural strength of 15.27 and 20.40 MPa, respectively, out of all the configurations and an improvement of 42% and 85% over pure LLDPE. Hybrid composites having high‐strength fibers in the skin layer exhibited superior mechanical properties. Microscopic examination of the fractured specimens revealed that fiber pull‐out and fiber breakage were the primary failure mechanisms of failure. Lateral failure due to delamination between matrix and fiber was predominant with grip and gauge regions as frequent failure points. The incorporation of sisal and jute fiber reinforcement into the polymers doesn't change the thermal stability of the fabricated composites significantly. The above results show that microwave‐assisted processing is a promising method for producing natural fiber‐reinforced hybrid polymer composites.Highlights Development of hybrid laminates using microwave energy at 2.45 GHz.
