Carbon-fiber-reinforced epoxy-matrix composite (CFRP) laminates with thin plies have strong damage-resistance properties compared standard prepregs. The static and fatigue tensile fracture behavior of cross-ply CFRP should be further studied to establish the applicability thin-ply prepregs for industrial structures. In this study, cross-ply, high-strength polyacrylonitrile (PAN)-based carbon-fi...

Three-dimensional (3D) printing with continuous carbon-fiber-reinforced polymer (C-CFRP) composites is under increasing development, as it offers more versatility than traditional molding processes, such the out-of-autoclave-vacuum bag only (OOA-VBO) process. However, due to layer-by-layer deposition of materials, voids can form between layers and weaken some parts’ properties, interlaminar she...

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...

Welded beam-column connections may be vulnerable to failure under cyclic loading conditions. These might require strengthening resist static and loads as they exhibit inadequate capacity due the design errors or material properties degradation because of severe environmental effects an increase in service loads. With this mind, a series full-scale experiments have been conducted investigate beh...

Manufacturing carbon-fibre reinforced polymer (CFRP) composites via different techniques often leads to contrasting surface topographies. Such differences can affect any subsequent pre-treatments that are performed and these ultimately joint strength. In the present work, CFRP adherends made using compression moulding or autoclaving were investigated. Pre-treatment of acetone cleaning, plasma t...

Currently Carbon Fiber Reinforced Polymer (CFRP) is widely used in the aircraft and automotive industries, due to its superior mechanical properties such as lightweight, high resistance which are very good for corrosion resistance. The components made of CFRP composites have their constraints, namely phenomenon delamination when composite material drilled. To analyze this phenomenon, it necessa...

Owing to high specific strength and designability, unidirectional carbon fiber reinforced polymer (UD-CFRP) has been utilized in numerous fields to replace conventional metal materials. Post machining processes are always required for UD-CFRP to achieve dimensional tolerance and assembly specifications. Due to inhomogeneity and anisotropy, UD-CFRP differs greatly from metal materials in machini...
