“…Then, the surface quality of holes is influenced by cutting conditions and tool geometries. 25,26 Several experimental studies confirmed that including the most critical factors in determining the surface roughness is the feed speed. [27][28][29] Besides that, many authors confirmed that there is an increase in the surface roughness by the increase of the number of cutting edges and the helix angle.…”

Among advanced cutting methods, High Speed Milling (HSM) is often recommended to improve the productivity and to reduce the costs of machining parts. As every cutting process, HSM is characterized by some defects like surface roughness and delamination are the main defects generated in composite materials. The aim of this experimental work is the studying of the machining quality of woven Carbon fiber reinforced plastics (CFRP) using the HSM technology. Experiments were done using different machining parameters combinations to make opened holes in CFRP laminates. This study investigated the effect of cutting speed, orbital feed speed, hole diameter on the delamination defect and surface roughness responses generated in the drilled holes. The design of experimental tests was generated using the approach of Central Composite Design (CCD). The characterization of these responses was treated with the Analysis of variance (ANOVA) and Response surface methodology (RSM). Results showed that the surface roughness is highly affected by the orbital feed speed (F) with contribution of 22.45%. The delamination factor at entry and exit of holes is strongly influenced by the hole diameter D (25.97% and 57.43%) respectively. The developed model equations gave a good correlation between the empirical and predicted results. The optimization of the milling parameters was treated using desirability function to minimize the surface roughness (Ra) and the delamination factor simultaneously.

“…A software model developed in-house considering moisture absorption parameters like moisture content at a given time within the initial absorption curve, that is, linear portion, slope of linear portion, diffusion coefficient, and so on, to predict the maximum or saturation moisture content and also the time of saturation mainly using equations (1) and (2). It was observed that the predicted results and the experimental results were in close correlation for conditions 70 C/85% RH and 55 C/100% RH.…”

“…Use of carbon fiber-reinforced plastic (CFRP) composites is increasing nowadays due to reduced weight along with the increase in strength and stiffness. 1,2 These widespread applications are mainly in aerospace and automotive industries. In their service life, composite structures are usually subjected to a variety of environmental situations, such as hygrothermal, chemical environments, UV radiation, biological conditions, and so on, which produces degradation in material properties.…”

Unidirectional carbon fiber-reinforced plastic (CFRP) IMA/M21E polymer composite was manufactured by standard autoclave curing method. This is a new aircraft-grade CFRP composite presently used in the manufacture of aircraft wing parts. Test specimens as per ASTM standards for weight gain, tensile and compression tests were obtained from this composite laminates. Some of the test specimens were subjected to hygrothermal (hot–wet) aging in an environmental chamber under three different conditions, that is, (i) 45°C/85% relative humidity (RH), (ii) 70°C/85% RH and (iii) 55°C/100% RH until reaching moisture absorption saturation. Matrix-dominated mechanical properties, that is, transverse tensile and longitudinal compression were determined for dry and hygrothermally aged test specimens. During mechanical testing in a servo-hydraulic test machine, the respective hygrothermal conditions were maintained while testing. It was noted that the rate of moisture absorption increases progressively and reaches saturation around 0.76–1.24 wt% depending on the aging conditions. Moisture absorption followed Fickian diffusion behavior in all the conditions of the study. Also, a software program was developed to predict the moisture content and time of saturation. The predicted results from this software program correlated with experimental results. It was observed that the presence of moisture reduced the tensile strength significantly by about 9–31% and compression strength by about 2–8%. Microscopic observation of tested samples was carried out using scanning electron microscope to study the failure behavior.

“…Conversely, several difficulties are encountered during these machining processes; which include high tool wear, fraying of composites, formation of burs and fibre-matrix interface damages. 10,11 Due to the existence of such difficulties, there arises a demand for a cost-effective and minimum damage material removal solution for FRP composites. 12 Machining using abrasives, typically grinding operations, have shown the ability to meet precision requirements.…”

Feasibility studies on wet grinding of carbon fibre reinforced epoxy polymer at minimum defect condition via eccentric sleeve grinding

Although surface grinding is reported to be capable of precision material removal in carbon fibre reinforced epoxy polymer composites (CFRPs), it is highly limited by deprived cutting temperature dissipation, tool wear and sensitivity to undesired cutting defects. Continuous engagement of abrasive grains and successive accumulation of heat at cutting interface in conventional surface grinding results in severe surface damages. Though the controlled application of cutting fluids exhibited improved surface integrity, entrapment of fluid droplets into the defective zones/cracks of fibre, matrix and its interfaces are shown to be stimulating further defect propagation. Present paper investigates the feasibility of improving cutting fluid application in CFRP grinding, establishing a minimum surface defect condition through eccentric sleeve grinding (ESG). The reduction of post-grinding surface defects through an intermittent-progressive cutting scheme in ESG is demonstrated and the efficacy of cutting fluids in such a grinding scheme is illustrated through the comparison of grinding forces and surface characteristics.
