In this paper, the conducting polymer fibers have been obtained by melt mixing and chemical coating on the fibers. Different conductive materials have been used in order to obtain conductive polypropylene-based fibers with specific electrical and mechanical properties. The electric conductivity and morphological characteristics of these fibers have been investigated...
The research described in this paper involves both nondestructive evaluation and destructive testing of an FRP honeycomb specimen. The specimen is representative of an FRP bridge that was tested in fatigue at Clarkson University prior to its arrival at Tulane University. The specimen was loaded and unloaded on several different...
Fiber reinforced polymers FRPs are promising materials for reducing vehicle mass, thereby improving energy efficiency and US energy security. The cost of using FRPs, especially with carbon fiber reinforcement, is quite high in comparison to conventional materials, and the lack of market incentives prevents their widespread use in passenger automotive...
Polymeric optical fiber POF is used for simple light guide and illumination applications. The polymer optical fiber materials can be utilized in flexible lighting elements, which can be combined with textile structures. The POF woven fabrics are introduced as a flexible alternative to lighting elements. This paper discusses various light-emitting...
Fiber reinforced polymer FRP bars have lower modulus of elasticity than steel bars. For this reason when FRP bars are used as flexural nonprestressed reinforcement in concrete sections, the stress in the FRP is limited to a relatively small fraction of its tensile strength. This limit, necessary to control width...
An environmental aging test protocol for evaluation of environmental durability of concrete wrapped with fiber-reinforced polymer FRP composites is proposed. The wrap material was made of E-glass and aramid woven fabric impregnated in an epoxy resin matrix. The effect of temperature, moisture, pH level, and freezing and- thawing cycles on...
