Carbon fiber reinforced polymers (CFRP) are a widely used composite material applied in both commercial and industrial utilization. Based on the heat conduction theory, theoretical model for temperature rise of braided CFRP irradiated by long pulse laser is established this work, time required maximum (with different thicknesses) to be acted with energy densities widths simulated. At same time,...

Carbon fiber reinforced polymer (CFRP) composites are increasingly being used to strengthen structures and retrofit existing structures. CFRP in various industries: construction, automotive, many others. This literature review has shown that find numerous practical applications. Improving by reinforcing them with composite is an innovative approach design. aims explore the current state of art ...

Pull-out experiments were performed on three carbon fiber-reinforced polymer (CFRP) ground anchors simulating their applications in different rock types which provided different confinement levels. The CFRP tendons comprised, on the ground side, a prefabricated conical anchor body of high-strength grout in which two CFRP straps were embedded. The anchors reached an average load-bearing capacity...

Composite hydraulic cylinders are used to reduce the weight of construction equipment such as aerial work platforms or excavators. The is compensated by manufacturing from Carbon Fiber Reinsforced Plastic (CFRP), but this expensive. Therefore, study investigated a hybrid cylinder, which combination CFRP and steel, considering both performance cost. conventional cylinder rods made can prevent fa...

Research on the use of CFRP materials for retrofit and strengthening of steel bridges and structures has increased in recent years. In order to implement these types of strengthening systems to longer span members, it is important to establish an effective method to splice adjacent lengths of CFRP laminates. This paper describes an experimental program to investigate the bond behavior of carbon...

In conventional manufacturing processes of composites, Carbon Fibre Reinforced Plastic (CFRP) laminates have been made by stacking unidirectional or woven prepreg sheets. Recently, as a manufacturing process of CFRP, 3D printing of CFRP composites has been developed. The 3D printing process of CFRP composites enables us to fabricate CFRP laminates with arbitrary curvilinear fibre plies. This in...

Carbon Fiber Reinforced Polymer (CFRP) laminates are applied to many aerospace structures. For these laminated CFRP structures, it is quite difficult to detect internal damage such as delamination, matrix cracks, and local fiber breakages. Carbon fibers are adopted as reinforcement in CFRP and it is an excellent electric conductor at the same time. The carbon fiber has been used as a strain sen...

This paper investigates the effects of unequal compressive and tensile moduli of carbon fibre reinforced plastic (CFRP) composites. The basic assumption is based on the statistics that the compressive modulus is a fraction lower than the tensile modulus. Data evaluated by Finite Element Analysis (FEA) model, Classical Laminate Theory (CLT) model, and experiment are used to investigate these eff...
