Silk has enormous potential as a next-generation material: it is a biopolymer spun from protein at ambient temperature and pressure, and the best spider silks are as strong as steel and tougher than Kevlar. Because of its green production, mechanical robustness, and biocompatibility, silk has been studied for use in a range of engineering and biomedical applications. However, despite exciting r...

The propagation characteristics of an acoustic point source generated using laser-induced plasma (LIP) were investigated experimentally. Experiments performed in a Kevlar-walled hybrid anechoic wind tunnel (HAWT) where the sound LIP was measured 251-element microphone array, while flow speed empty test section varied. time instant formation also captured. far field pressure assessed through arr...

Quest to reduce challenges of high structural weight and cost metallic components is increasing. It has led their replacement with carbon Kevlar fibers reinforced polymer (FRP) composites. These aforementioned problems can be further solved through hybridization carbon/glass (CG) Kevlar/glass (KG) the manufacturing materials usage, not at detriment properties. Also, investigation into tensile p...

Abstract One of the applications composites is in manufacturing tubes, which are widely used industries such as petroleum, petrochemical, and aerospace. Composite tubes made thermoset resin base material reinforced by fibers, having a solid, lightweight, corrosion-resistant structure, great replacement for metal concrete tubes. In this research, composite with various resins material, Swancor90...

The role of liquid crystalline mesophases in polymer crystallization has seen increased attention following the observations of meta-stable liquid crystalline pre-ordering in the crystallization of isotactic polypropylene and other flexible polymers [1–7]. In addition to these recent observations, both in Nature and industry liquid crystal mesophases are used to create polymeric materials with ...
