Formation mechanism and morphology prediction of CFRP

In order to solve the issue that it is difficult to removing the powder chips of carbon fiber–reinforced polymer (CFRP), the chip morphology prediction model for single-layer composite materials and the 3D drilling model and the chip formation process for laminated composites are developed to study the chip formation mechanism. It is concluded that drilling chips are mainly tower-shaped

Edge Delamination and Residual Properties of Drilled

Edge delamination is frequently observed in carbon fiber reinforced plastic (CFRP) laminates after machining, due to the low fracture toughness of the resin interfaces between carbon fiber plies. In this study, the effects of incorporating tough aramid fibers into the brittle CFRP system are quantified by measuring the residual properties of bolted CFRP. By adding short-aramid-fiber

In the present work a three-dimensional (3D) finite element (FE) model is developed to study the machining of unidirectional (UD) carbon fiber reinforced polymer composite (CFRP). Chip formation process and ply damage modes such as matrix cracking, fiber matrix shear, and fiber failure are modeled by degrading the material properties.

Rao et al. [13] developed a three-dimensional macro-mechanical finite element (FE) model to study the machining response of unidirectional (UD) carbon fiber reinforced polymer composites. It was found that the cutting force increases with fiber orientation and depth of cut but is less influenced by rake angle.

Carbon fiber reinforced polymer (CFRP) composites have been widely used in aerospace, aviation, and automotive industries due to their high strength/stiffness-to-weight ratios, high temperature resistance and corrosion resistance. CFRP components are usually produced in near net-shape, and cutting operations such as drilling, slot milling, and edge trimming are required to remove excessive

Edge trimming is a necessary machining operation to achieve the required dimension and surface quality of carbon fiber reinforced polymer (CFRP) components. Rapid tool wear occurs during the edge trimming process owing to the high strength and abrasive nature of the carbon fibers, leading to potential surface damage. To satisfy the production efficiency and part quality requirements
