“…The pre-oxidized fibres are fully released, and tangled large fibres are released in small pieces of fibres or bunches through tearing; even the single fibre state is shown. Given the poor electrical conductivity of PAN pre-oxidised fibres, which easily produce static in the process of friction with the parts, and in order to carry out the subsequent processing smoothly, pre-oxidised fibres after the opening are required to be evenly sprayed with an antistatic agent, then they are packaged for 24 hours in a plastic bag [20][21][22][23][24].…”

Many factors were needed to be considered to prepare pre-oxidised fibre felts with excellent heat insulation performance, and different production processes showed differences in the heat insulation performance of pre-oxidised fibre felts. In order to probe into the influence of the production process on the heat insulation performance of materials, a large number of experiments were needed to be carried out. For needle-punched nonwoven pre-oxidised fibre felts, web features, needle characteristics and the needle process will all affect the structure of pre-oxidised fibre felts, thus bringing a major influence on the heat insulation performance of pre-oxidised fibre felts. In this paper, the influence of the needle number on the heat insulation performance of pre-oxidised fibre felts was mainly studied. Results showed that an increase in the needle number will cause a decrease in the thickness and gram weight of pre-oxidised fibre felts, and a weakening trend in the heat insulation performance of pre-oxidiaed fibre felts with an increasing needle number at room temperature and at 100-200 °C was shown. Moreover when the needle number was 1 and 2, the pre-oxidised fibre needled felts had good heat insulation performance, and for pre-oxidized fibre felts at different needle numbers with increasing temperature, the temperature difference in a steady state increased linearly.

“…By converting the phenolic resin matrix to a carbon matrix, the pyrolysis process could enhance the shear modulus due to the high sti ness of the carbon matrix. However, the shrinkage and mass loss during pyrolysis created the porous microstructure that reduced the strength of the composite [26]. It was reported that carbon from phenolic resins contained a high content of closed pores [25], whereas the open porosity could a ect the thermal expansion and oxidative stability of the C-C composite.…”

In this work, composites based on phenolic resin (P), graphite powder (G), carbon fibers (CFs), and carbon nanotubes (CNTs) were prepared by using hot compression molding. The effect of CNTs on the microstructure and thermal property of these composites was investigated. FESEM analysis indicated that the surface structure of phenolic/graphite composites became more dense and homogeneous with the presence of CNTs. The carbonization behavior of composites was characterized by using thermal gravimetric analyses (TGAs). TGA data showed that the presence of CNTs in phenolic/graphite composites enhanced their thermal stability, by increasing the temperature of maximum weight loss rate (Tm) during pyrolysis and decreasing the weight loss after pyrolysis. In addition, incorporation of CNTs into phenolic/graphite composites reduced significantly their open porosity.

Phenolic resin-carbon fiber composites are used in various industries due to their high flame resistance, high strength to weight ratio, and high thermal stability as an insulator. In this study, to expand the applications of this composite in marine structures, phenolic resin-carbon fiber-nanosilica composites were fabricated with eight layers of twill carbon fibers and 0, 1, 2, and 3 wt% of nanosilica then flexural and flame resistance was investigated. To evaluate the stability of the composites in seawater, the samples were placed in seawater for 30, 60, and 90 days then the flexural test was performed and the percentage of strength reduction was calculated. Thermogravimetric analyzer test was performed on a sample that had the highest strength after 90-day immersion.Finally, it was found that nanosilica particles had a significant effect on increasing the flexural strength and flame resistance of samples so that the sample with 3 wt% silica had flexural strength and burning rate of 690 MPa, 0.098 g/s, respectively.
