Machined surface quality determines the reliability, wear resistance and service life of carbon fiber reinforced plastic (CFRP) workpieces. In this work, the formation mechanism of the surface topography and the machining defects of CFRPs are proposed, and the influence of milling parameters and fiber cutting angles on the surface quality of CFRPs is obtained, which can provide a reference for ...

In this research, the influence of carbon nanotubes agglomeration on buckling behavior multi-phase CNTs/fiber/polymer/metal composite laminates cylindrical shells under hydrostatic pressure was investigated. Governing equations were derived according to Kirchhoff-Love’s first approximation shell theory and solved by a combination Galerkin Fourier series expansion methods. Equivalent elastic pro...

Abstract During deep drawing processes of fiber metal laminates, such as the newly developed in-situ hybridization process, fibers and sheets come into contact while dry fabric is infiltrated by a reactive matrix system. The viscosity increases polymerization starts during deep-drawing. In laminate drawn thermoplastic system injected glass layer in resin transfer molding process. forming lamina...

nowadays, tetrapack packaging materials are widely used in beverages such as juice, milk and water packaging applications. each year a significant amount of waste is producing in the world which are non-recyclable in other industries and will also cause environmental pollution. this paper outlines the panels made from tetrapack waste and investigation of physical and bending properties of these...

A novel, two-scale computational model has been developed to predict the progressive damage and failure responses of fiber-reinforced composite laminates using the material properties at the constituent (fiber and matrix) level. These properties were measured from coupon level tests on a unidirectional lamina of the same material system. In the proposed computational scheme, the macroscale fini...

Externally bonded carbon fiber reinforced polymer (CFRP) laminates are a feasible and economical alternative to traditional methods for strengthening and stiffening deficient reinforced concrete and prestressed concrete girders as shown in Fig. (1). Although extensive research has already been undertaken to investigate the behavior of CFRP strengthened bridge girders, the majority of work condu...

This paper presents the results of an experimental study to evaluate the damage and failure mode of hybrid-fiber engineered cementitious composite (ECC) panels caused by large projectiles or fragments with the aim towards quantifying the extent to which hybrid-fiber ECC improves the resistance of blast panels against impact loading. Drop weight tests are conducted on full-scale blast/shelter pa...
