“…Initiation of failure could be possibly be due to reduction in strength of the matrix, or reduction in the inter‐laminar strength/ bond. Consequently, the reduction in matrix strength prevents the load transfer between the matrix and fiber, hence causing the failure (Figure ) …”

Summary The recent attention in the applications of the fiber reinforced thermoplastic composite have raised some concerns because of the ability and performance of the fiber reinforced thermoplastic composite after long‐term exposures to environmental weathering (e.g., UV radiation, moisture, and oxygen). This weathering can be very destructive to the thermoplastic polymers; hence, a systematic study of the UV radiation effects on the properties of fiber‐reinforced thermoplastic composite is crucial for industrial applications. The major objective of the project was to study the correlation between thermoplastic fabrication parameters and the final properties of composites. In this study, carbon fiber (CF) reinforced polyphenylene sulfide (PPS) thermoplastic composites were manufactured using high temperature press after optimizing the parameters. Subsequently, the effects of long‐term UV exposures on the thermal and mechanical properties of CF/PPS thermoplastic composites were investigated in detail. The test results showed that the correlation between the processing parameters and the physical properties of the laminate composites were in all good agreements. The test results also revealed a significant decrease in the glass transition temperature, as well as storage modulus, and tensile strengths. Furthermore, short (200 hrs) and long (300 hrs) term UV exposures changed various thermal and mechanical properties of the thermoplastic PPS composites. This study can provide some preliminary knowledge to engineers and scientists in the field and develop new set of structural composites.

“…These meshes can be comprised of aluminium (Al), copper (Cu) or bronze (CuSn) wire, and can either be co-woven or commingled with the carbon fibre in a prepreg or fabric ply, or bonded separately as a mesh to the outermost laminate layer [7,8]. However, in the case of aluminium mesh, galvanic corrosion can occur if moisture penetrates the composite's exterior skin [9]. Galvanic action can be particularly severe for metals with low electrode potentials.…”

Carbon fibre reinforced plastics (CFRPs) are intensively used in modern aircraft structures because of their superb specific mechanical properties. Unfortunately their electrical and thermal conductivities are not sufficiently high for some applications like electromagnetic interference (EMI) shielding and lighting strike protection (LSP). The addition of external metallic structures, such as aluminium or copper mesh, is generally required, with a compromise in terms of increased mass and manufacturing cost as well as reduced corrosion resistance. In the present work spray coating of carbon nanoparticles was utilised as a simple method to locally increase the electrical and thermal suface conductivity of CFRPs. The combined use of carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs) synergistically reduced the CFRPs surface resistivity by four orders of magnitude (from 2-3 Ω/sq to 3×10-4 Ω/sq) and increased the thermal conductivity by more than 7 times (from 200 W•m-1 •K-1 to 1500 W•m-1 •K-1), opening up possibilities for the replacement of metallic mesh structures for EMI shielding and LSP. An analytical model was introduced based on a one-dimensional heat conduction approach to predict the effective thermal conductivity for the hybrid nanofiller coating layer and its findings showed good agreement with experimental data.

“…Nevertheless, the metallic meshes embedded in carbon fiber structures increase the weight of the structure. Moreover, they are susceptible to pitting, oxidation and galvanic corrosion, and hence lose their electrical conductivity over the time [7]. To embed the mesh more effectively in the composite structure, many aerospace material suppliers impregnate the metallic mesh with adhesive films, surfacing films, or prepregs.…”

A thin flexible coating made of pristine graphene was fabricated and applied on the surface of a commercial carbon fiber epoxy prepreg laminate to protect it against the lightning strike. To assess the coating's effectiveness, the coated laminate was subjected to the simulated lightning strike as well as the electromagnetic interference shielding effectiveness (EMI SE) testing. It was observed that the damaged area and volume in the coated laminate were reduced by 94% and 96%, respectively, as compared to the laminate without the coating. Moreover, the coated laminate had an average EMI SE of 51 dB over 100-2000 MHz range, 55 dB over 8-12 GHz range, and 60 dB over 12-18 GHz range marking 22%, 44 %, and 49% improvement in EMI SE for each frequency range, respectively. The results indicate a great potential for the developed coating to protect the commercially available prepreg composites against the lightning strike.
