The response over the low-velocity impact of various shape impactors on a glass fiber reinforced polymer composite has been numerically analyzed with hemispherical, flat, partially flat and truncated shaped impactor used to analyze behavior resistance GFRP at speeds. numerical analysis was carried out using finite element software, ABAQUS (Dynamic/Explicit). To assess laminates while impacting,...

Abstract Glass fiber-reinforced polymer materials have been effectively used in civil aviation aircraft, but due to low electrical conductivity, a large area of ablation damage will occur after lightning strikes, which greatly threatens the safety aircrafts. Based on this, coupled electrical-thermal finite element analysis model for glass fiber reinforced is established, and results are compare...

The creep and dynamic mechanical behavior of natural fiber/epoxy composites using functionalized multiwalled carbon nanotubes (MWCNTs) modified matrix were investigated. 0.4 wt% of MWCNTs functionalized with carboxylic acid groups (MWCNTs-COOH) were dispersed in epoxy and three-phase multiscale hybrid composites were processed by hot press. Natural fiber/epoxy two-phase composites without MWCNT...

The influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. The incorporation of nanoclay into epoxy enhances the impact resistance of the composites. The impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...

Fiber-reinforced 3D printing technology offers significant improvement in the mechanical properties of resulting composites relative to printed (3DP) polymer-based composites. However, 3DP fiber-reinforced composite structures suffer from low fiber content compared traditional composite, such as orthogonal woven preforms solidified with vacuum assisted resin transfer molding (VARTM) that impede...

The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...

Fiber-reinforced asphalt concrete (FRAC) was tested using limestone, PG 64-22 binder, and 20% reclaimed pavement (RAP). After mixing fibers with different lengths dosages, they were extracted recovered to evaluate their dispersion in the FRAC. The uniaxial fatigue test, IDEAL CT flow number test performed on FRAC fiber contents. balanced mix design (BMD) approach then used analyze results order...
