“…A high-quality cut can be sought with the use of laser cutting because of the control of processing parameters available by laser systems. Some of the key factors that have an impact on laser cutting of composites are speed of cutting, distance between cutting head and work piece, scanning speed, number of passes, diameter of gas nozzle and presence of cooling assist gas [2]. Laser cutting, if not optimized based on the above factors, can have a significant impact on the material and its strength i.e.…”

Carbon fiber reinforced plastic (CFRP) is extensively used in automotive and aerospace industries with the aim to achieve reduction on emissions by reducing weight. Due to governmental regulations to reduce the environmental impact and to reduce waste, the need for remanufacturing CFRP is becoming an interesting area of application with economic benefits to industry. This is important as manufacturing carbon fiber is a costly process and remanufacturing CFRP is more cost effective and reduces the dependency on virgin materials. Processing CFRP to meet demands, for fast and high-quality cuts, can impose problems for conventional methods. The use of multi-pass scanning technique in laser cutting CFRP is investigated using a 1.5 kW fiber laser with assist gas pressure of 16 bar and gas flow rate of 126 lt/min. Using multi-pass technique, a through cut can be obtained by repeating the beam travel more than once. The advantage of laser cutting when compared with traditional CNC, is the low cost of maintenance over time due to the non-contact nature of the process i.e. no wear of tool at contact area. And due to the small beam spot size of the laser small and complex shapes can be cut. The aim of the paper is to determine how the process performs in terms of cutting speed and fiber damage. Average power was used to carried out experimental tests. A fiber damage below 100 µm with laser cutting speed of 2.5 m/min and above was obtained. Thermal effects were analyzed using scanning electron microscope (SEM) and optical microscope (OM). The fiber damage was further optimized using specialist methods such as double aperture nozzle and trenching. The use of trenching and double aperture further reduces the fiber damage to 10 µm and 50 µm, respectively with laser cutting speed of 7.5 m/min and 3.33 m/min.

The emerging “green” economy is based on energy efficiency, renewable food stocks in polymeric products, industrial processes that reduce carbon emissions, and recyclable materials. Natural fiber is a type of renewable source and a new generation of reinforcements and integrators for polymer-based materials. Because of its advantages over synthetic fibers, the use of natural fibers as reinforcements in composite materials has become important in recent years. To meet certain design criteria, natural fiber-reinforced composites impose certain secondary operations during assembly. Limited literature is available only in connection with the processing of natural fiber-reinforced composites. This paper analyzes a comprehensive review of the natural fiber-reinforced composite processing literature along with the challenges during processing.

“…The non-traditional machining processes like abrasive water jet machining (AWJM), laser beam machining (LBM), and electrical discharge machining (EDM) are utilized to cut FRPs. Nevertheless, these processes also have certain limitations which make them unsuitable for GFRP, such as, inability to fabricate blind machining features (by AWJM), 6,7 fiber damage, delamination, and heat affected zone (by Laser), [8][9][10] and restricted only for conductive composite (by EDM). [11][12][13][14] Micro-electro chemical spark machining (micro-ECSM) process is an emerging hybrid process that removes materials by the action of two simultaneous processes that is, micro electro chemical machining (micro-ECM) and micro electro discharge machining (micro-EDM).…”

In the present study, fabrication of micro-channel on glass fiber reinforced plastic (GFRP) sheet has been performed through micro-electrochemical spark machining process. Box-Behnken design has been followed to conduct experiments and the influence of machining parameters and their ranges that is, applied voltage (50 V–60 V), duty factor (35%–45%), electrolyte concentration (20–30 wt%), and pulse frequency (6–10 kHz) on the micro-channel quality has been investigated. The width of micro-channel (WMC), delamination extent (DE), and heat-affected zone (HAZ) are considered as the responses. Response surface method (RSM) with desirability analysis and multi-objective optimization are utilized to optimize the process. The minimum observed WMC, DE, and HAZ are 532.81, 1.09, and 50.52 μm respectively which are obtained at machining voltage: 50 V, duty factor: 35%, concentration: 20 wt% of NaOH, and pulse frequency: 10 kHz. The fiber breakage and re-deposition/adhesion of broken fiber and matrix materials are observed at the edges of the micro-channel.
