This paper considers the problem of determining the strength of carbon fiber reinforced plastic with straight and curved fibers under high-speed loading. High-speed tests of unidirectional CFRP specimens with rectilinear and wavy structure have been carried out. The influence of the structure and high-speed loading on the ultimate strength and ultimate deformation of the material is investigated. For the first time, a detailed study of the effect of fiber curvature on the properties of CFRP under high-speed deformation has been carried out. As a result of dynamic tests, it was shown that the ultimate strength in unidirectional laying is higher than in wavy laying. The effect of increasing the ultimate deformations of specimens with bent fibers was established, which was noted earlier for the case of tensile tests.

Recently, high-performance hybrid composites have been used for various applications which require the high strength, high stiffness and low weight. There are growing needs in an automotive, an aircraft, and military applications for composite materials since they have good structural characteristics. They also have good penetration resistance and structural integrity after impact. In order to clarify the mechanism of high-speed destruction for composite materials, this study examined the penetration resistance and the fracture behavior of CFRP (Carbon Fiber Reinforced Plastic) Laminates by using ballistic range (one-stage light gas gun). Test materials for investigation are carbon/epoxy laminated composite materials with fiber direction; [0°]8, [0°/45°]4s, [ 0°/90°]4s, [ 0°/45°/90°]3s and [ 0°/45°/-45°90°]2s. The high speed camera allows us to capture and analyze the dynamic penetration phenomena of the test materials.

The applications of carbon fiber reinforced plastic materials have increased widely in the fields of aerospace, automotive, maritime, and sports equipment because of their excellent mechanical properties. Machining of carbon fiber reinforced plastics has a considerably more complex effect on drilling qualities than machining of conventional metals and their alloys due to the nonlinear, inhomogeneous, and abrasive nature of CFRPs. This article addresses the methodologies that have been adopted to minimize the material damages in drilling of polymeric composite materials. Key papers are reviewed with respect to tool types, materials, geometry and coatings, back-up plate, coolants, environment, unconventional machining, and high-speed drilling methodologies, which influence the hole qualities of delamination, burr, surface roughness, cylindricity, diameter error, and thermal damage with the effect of cutting variables (spindle speed and feed rate). In addition, some deburring strategies are also reviewed and discussed.

In this work, high speed trimming of a multi directional carbon fiber reinforced plastic using a tungsten carbide burr tool is studied. The influence of the machining parameters on both the dust size and surface quality is investigated. A high percentage of dust is found under the theoretical chip size and the surface quality is found to be affected by the cutting parameters. The percentage of inhaled dust reaching the pulmonary alveoli is quantified and found to be very high, it is also found that this percentage is affected by the cutting conditions.
