resin transfer molding (rtm) is a composite manufacturing process. a preformed fiber is placed in a closed mold and a viscous resin is injected into the mold. in this paper, a model is developed to predict the flow pattern, extent of reaction and temperature change during filling and curing in a thin rectangular mold. a numerical simulation is presented to predict the free surface and its inter...

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...

In recent years, various new and practical products have emerged thanks to rapidly developing science technology meet human needs expectations. A variety of these are materials known as composites. The use composites is also increasing, from the aircraft industry automobile industry, other areas such sports equipment, infrastructures. goal this research present a hybrid composite material that ...

In this work, the mode I fracture toughness of dissimilar metal-composite adhesive joints is experimentally investigated using double cantilever beam (DCB) test. The particular joint under study resulted by joining a thin titanium sheet with carbon fiber reinforced plastic (CFRP) laminate and envisioned to be implemented in hybrid laminar flow control system future aircraft. Four different indu...

Resin transfer molding (RTM) is a popular manufacturing technique that produces fiber reinforced polymer (FRP) composites. In this paper, a model-assisted flow front control system is developed based on real-time estimation of permeability/porosity ratio using the information acquired by a visualization system. In the proposed control system, a radial basis function (RBF) network meta-model is ...

Damage detection methodology utilizing A-scan and C-scan concept for detecting flaws for composite structure has been presented Ultrasonic bulk wave has been used for non-destructive testing of the composite specimen. Carbon fiber composites have been tested for different types of damages using longitudinal waves. Two sample specimens consisting of a de-lamination, a through hole, and resin ric...

Fiber-reinforced polymer composites (FRCs) have shown great promise as high strength structural materials due to their high stiffness to weight ratio and their ease in processing. They have found extensive use in aerospace, automotive, construction, and recreational equipment material applications. Research in polymer-based nanocomposites (PNCs) has shown explosive growth in the past decade wit...
