The Development of Compression Moldable Polymer Composite Bipolar Plates for Fuel Cells
… Tech is based on material generated by a wet-lay process and uses polyethylene terepthalate (PET) or polyphenylene sulfide (PPS) as the binder, although PPS is mainly used. In order to reach sufficient conductivity for use in generating bipolar plates, the polymer is doped with high levels …

Strengthening of Steel Structures with High Modulus Carbon Fiber Reinforced Polymers (CRRP) Materials: Bond and Development Length Study
… extensive research to select the resin for wet lay-up of carbon fiber sheets and the adhesives for bonding of pre-cured laminate strips. The bond behavior of FRP materials to steel structures is quite different from that of concrete structures. Preliminary test results showed the occurrence …

Durability of fiber-reinforced composite wrap system for the rehabilitation of concrete structures
… x 8&inches; in dimensions) wrapped with 1 layer of glass fabric embedded in an epoxy resin matrix were used to simulate the field situation. Wet lay-up method was used to wrap the concrete cylinders where the epoxy also served the purpose of bonding the composite to the concrete. Specimens …

Polyimide/silica nanoparticle-modified epoxy resin and kevlar/glass fiber-reinforced polymer matrix composites for potential application in commercial aircraft radomes
… glass fiber polymer matrix composites via the wet lay-up and vacuum bagging techniques by utilizing epoxy resins modified with Polyimide (PI) and 2wt.% to 8wt.% of KH-550-modified silica nanoparticles. Dielectric constant tests revealed that the epoxy resin/Kevlar and epoxy resin/glass fiber …

Strengthening of timber beams using externally-bonded sprayed fibre reinforced polymers
… FRP mats, or application of FRP via the wet lay-up process. However, a new technique developed at the University of British Columbia allows for the application of FRP in the form of a spray. Externally bonded Sprayed FRP (SFRP) is known to increase strength and energy absorption capacity …

Improving the Quality of Laminates in Liquid Composite Molding Using Magnetic Compaction: Experiments and Process Model
… liquid composite molding (LCM) processes such as wet lay-up vacuum bagging (WLVB) and vacuum assisted resin transfer molding (VARTM) in composite manufacturing, they have two major drawbacks. First, the fiber volume fraction of the composite parts made by LCM is lower than those made under an …
