In tribological applications, because of the corrosive problems of the metals in water applications, poly-ether-ether-ketone (PEEK) and its composites are preferred for rubbing materials. As it is known PEEK is a high performance semi-crystalline thermoplastic polymer and has received significant attention in recent years. This is due to its high mechanical strength and elastic modulus, high to...

In response to the defects of easy delamination, poor impact resistance, and low toughness in laminates, intra-layer aramid/glass hybrid weft-knitted reinforced composites without lamination were designed prepared. This paper investigated tensile, bending, composites. Homogeneous with glass: aramid ratios 1:1, 2:1, 3:1, modes transverse hybrid, oblique vertical interlocking prepared by vacuum r...

Abstract Composite materials are more and widely used in aircraft structural design, impact damage is the most serious defect/damage form of aviation composite structures service. Therefore, it great significance to study resistance composites with different forms for design. In this article, reinforced fiber/resin laminates unidirectional carbon fiber prepreg (UIN23100), woven fabric (W-3021FF...

Abstract: A new reinforced SFRFLC (abbr. steel fiber reinforced full-lightweight concrete) superposed beam was proposed to sufficiently utilize the good peculiarities of ordinary concrete in compression and SFRFLC in tension, and reduce its self-weight. Experimental study was carried out on the flexural behaviors of reinforced SFRFLC superposed beams compared with reinforced concrete beams and ...

Fiber-reinforced composites are an ideal high-performance composite material made from a combination of high-strength continuous fibers and polymer matrix. Compared to short cut fibers, long strand can improve the mechanical properties fiber more effectively. Herein, aramid fiber-reinforced PLA filaments with centering were prepared by modifying outlet design desktop-grade thermoplastic single-...

The combined effect of the use of carbon fiber and seawater and the molecular structure on the tribological behavior of various polymer materials under natural seawater lubrication was investigated. After the investigation, the wear morphology of the contact surface was observed by a laser scanning confocal microscope, and the texture of the wear scars and tracks were presented in 3D profiles. ...

Abstract The fiber reinforced polymer (FRP) armor composites are kinds of composite materials specially designed and manufactured to prevent the penetration high-speed bullets fragments. FRP commonly composed reinforcing fibers, resin matrix their interfacial structures. vinyl ester (VER) is a kind thermosetting applied in field high performance bulletproof composites. However, VER has problem ...

Synopsis: Advantages such as light weight, high mechanical properties and resistance to aggressive and chemical agents, non invasive installation, low tooling and machinery costs, possibility to repair the structure without interrupting its use have determined great expectation on Fiber Reinforced Polymer (FRP) composites for the strengthening of civil structures. However, their diffusion is of...
