Functionalized composite structures for new generation airframes: a review

Characterization and analysis of carbon fibre-reinforced polymer composite laminates with embedded circular vasculature

“…In addition, it can also be confirmed that with the IM7/8552 composite laminate, the compression failure mechanism The point of crack initiation is difficult to precisely determine, as has been reported by other researchers (Ye et al 2005;Kousourakis et al 2008). Hence, the coefficient of variation of crack initiation stress is In the FEA predicted results, crack initiation stress is between 60 and 75 per cent of final failure; while experimental crack initiation stress ranges from 70 to 80 per cent of failure strength.…”

“…Fibre-reinforced polymer (FRP) composites are gradually taking the place of metal alloys for significant parts of the primary structure in modern aircraft and their performance is key in determining reliability, performance, gross weight and cost-effectiveness of the vehicle (Ye et al 2005). In such high-end applications, relatively minor damage within a composite material may result in a significant reduction in overall performance.…”

Tooling design and microwave curing technologies for the manufacturing of fiber-reinforced polymer composites in aerospace applications

“…The characteristics of composites determined that it can only be achieved by the integration of digital design and manufacturing technologies. The design and processing method for aircraft structures of polymer composite materials have been described in numerous books and papers, including those by Schwartz [16] and Ye [17].…”

“…Ao [29] reported that composite tooling can provide high accuracy of radar antenna, e.g., the accuracy of composite antenna can be less than 0.04mm. Fan and Zhang [17] investigated large size and critical dimensional and geometric accuracy aircraft composite parts, and predicted that more large complex composite structures will be used in military and civil aircrafts, and the corresponding tooling should be fabricated. A composite tooling of 4m width, 8m length is fabricate by Hexcel Company applied in the future A350 XWB aircraft fuselage panels [30].…”

Self-healing of low-velocity impact and mode-I delamination damage in polymer composites via microchannels

“…However, their poor out-of-plane mechanical properties make them susceptible to various damages like impact, inter-ply delamination and interlaminar shear that result in performance degradation of composite structures [1][2][3]. Moreover, in most cases, these damages lie beneath the surface or barely visible and a lot of non-destructive (NDT) inspections are necessarily performed to seek their presence and prevent catastrophic failure of structure [4,5]. Consequently, large factors of safety are incorporated in design to ensure their safety and reliability, which lead to composite structures with higher weight and thicker sections.…”
