A low concentrated polystyrene (PS) additive to epoxy is used, since it is able to reduce the curing reaction rate but not at the cost of increasing viscosity and decreasing glass transition temperature of the curing epoxy. The modified epoxy is cocured with a compatible thermoplastic interleaf during the vacuum assisted resin transfer molding (VARTM) to toughen the interlaminar of the composit...

The problem of improving the delamination resistance and toughness of laminate fiberreinforced composites especially for the drop-off structure is receiving considerable attention with the increasing need and application in industries. A hot melt-bonding process is developed to bond glass fabric laminates and the thermoplastic (TP) polysulfone (PSU) interleaf prior to the vacuum assisted resin ...

Resin injection such as resin transfer molding (RTM) is commonly applied in industry for serial production of composite components. RTM process simulation enables prediction of process parameters that are essential for component and tool design. As for all simulations where material behavior is modeled, validated material properties are indispensable for realistic simulations. Currently, materi...

Triple-shape memory epoxy (EP)/polycaprolactone (PCL) systems (PCL content: 23 wt %) with different structures (PCL nanoweb embedded in EP matrix and EP/PCL with co-continuous phase structure) were produced. To set the two temporary shapes, the glass transition temperature (Tg) of the EP and the melting temperature (Tm) of PCL served during the shape memory cycle. An attempt was made to reinfor...

In the present study experimental and numerical investigations were carried out to predict the low velocity impact response of four symmetric configurations: 10 ply E Glass, 10 ply AS4 Carbon, and two Hybrid combinations with 1 and 2 outer plies of E Glass and 8 and 6 inner plies of Carbon. All numerical investigations were performed using commercial finite element software, LS-DYNA. The test c...

Kenaf fiber-polyester composites incorporated with powdered activated carbon (PAC) were prepared using the vacuum-assisted resin transfer molding (VARTM) process. The product demonstrates the electromagnetic interference (EMI) shielding function. The kenaf fibers were retted in a pressured reactor to remove the lignin and extractives in the fiber. The PAC was loaded into the freshly retted fibe...

Fiber-reinforced polymer composites have a fast-growing performance in many areas of engineering as replacement for metallic materials due to their low density, cost, specific mechanical characteristics, and lower energy consumption. The efficiency fiber-reinforced at high temperatures is an issue that requires be well investigated before this type composite can used important fields. aim study...

In this study, the effect of different curing temperatures (60°C,80°C, and 100°C) on mechanical characteristics Jute Glass fiber-based hybrid composites were analyzed mechanically, physically, morphologically. fiber fabric glass fabrics (49 gr/m² 100 gr/m²) used as reinforcement elements, while epoxy was utilized ma-trix materials. A vacuum assisted resin transfer molding method (VARTM) product...
