“…At present, C/C components with large sizes and complicate shapes are extensively used in the fields of aerospace, aviation and industry. However, it is difficult and expensive to prepare large size and complex structure C/C components directly because of their brittle characteristic, high cost of processing as well as long preparation cycle [6][7][8]. One alternative way is to join several small, simple C/C parts into the large, complicated components.…”

“…[7][8][9] This phenomenon has been verified through subsequent investigations by numerous researchers, though the degree of degradation differs depending on the material characteristics. [10][11][12][13][14][15] Research by Wang et al 17 and Hwang et al 18 showed that the bonded joint strength in a mixture of environments varied with the exposure temperature and duration. The chemical change with time was investigated using attenuated total reflection (ATR) infrared spectroscope analysis.…”

The effect of moisture and temperature on the strength of composite single-lap bonded joints were extensively investigated. Secondary bonded-joint specimens were immersed in tap water and 3.5% salt water at 71 C for different durations up to a maximum of 300 days. A total of 160 specimens were tested under six different moisture contents and two different temperature environments. Test results showed that while the strengths of the joints with 2.1% or more tap water moisture content decreased compared with those of dry joints, the strengths of pre-saturated joints with up to 1.0% moisture content increased at both room and elevated temperature. However, the strengths of saturated joints at 2.5% moisture content decreased by 34% (room temperature) and 44% (71 C) compared with those of the dry joints. In the joints with 1.0% or lower moisture content, the higher temperature environments resulted in slightly increased strengths, whereas the elevated temperature degraded the strengths in the joints with 2.1% or greater moisture content. The major failure modes of the joints were delamination and intralaminar failure of the composite adherend; the joints with high moisture content tested under elevated temperature showed cohesive failure of adhesive. The strengths and failure modes of the joints that were immersed in salt water did not show a remarkable difference from the joints that absorbed tap water.

“…Owing to the excellent high‐temperature mechanical properties, carbon/carbon (C/C) composites are considered the ideal high‐temperature structural materials in aeronautic and astronautic fields . Currently, the need for large and complex geometry high‐temperature structural materials increases steadily . Joining of C/C composites to themselves or ceramics is a key technique for addressing this issue .…”

Improving the SiC–Si/MAS interface is essential for enhancing the SiC–Si/MAS joint strength. In this work, well‐dispersed SiC nanowires (NWs) were in situ synthesized at the SiC–Si/MAS interface in the joints as the anchors, which made the fracture feature of the joints change from SiC–Si/MAS interface fracture to MAS fracture, resulting in an obvious improvement of the shear strength. The results showed that the average shear strength of the joints was increased by 49% by in situ synthesizing SiC NWs, which was primarily attributed to the excellent interface anchoring effects of SiC NWs involving the interfacial bonding anchoring between SiC NWs and SiC–Si layer and the mechanical interlocking anchoring between SiC NWs with the junctions and the surrounding grains. This study may provide new insight into the anchoring mechanisms and suggest a new design methodology for nanowire joints, leading to improved joint strength.
