WebComposite materials are used in aircraft structures to reduce the weight of aircraft and minimize assembly time, owing to their high strength-to-weight ratio and stiffness-to-weight ratio, etc. [1,2].Figure 1 shows the composite parts that are used in Boeing 787 aircraft. The brittle nature of composite materials elicits concern about their ability to resist damage … Webthe literature review was to identify candidate damage tolerance test methodologies for sandwich composites to be investigated for possible inclusion in a standardized test. A comprehensive report reviewing damage resistance and damage tolerance of sandwich composites has been published by Tomblin et al. [5]. This report summarizes
WebDec 16, 2024 · Abstract. This paper investigates the damage development in SiC/SiNC woven composites under tensile and cyclic loading both at room and elevated temperatures. The ultimate strength, failure strain, proportional limit and modulus data at a temperature range of 23°C–1380°C are generated. The tensile strength and the modulus …
WebApr 11, 2024 · In the last few decades, many studies have been published on the static mechanical properties of bonded repaired structures [4, 5, 10, 11] and the impact damage tolerance of composite laminates [12, 13]. Considering that the repaired structures are also susceptible to LVI events, impact damage resistance and damage tolerance have …
WebApr 7, 2024 · Here, the lightning strike damage tolerance of the composite specimens is evaluated by checking the retentions of the flexural modulus and strength after the lightning strike.
