Thermal Modes And Thermal Insulation Properties Analysis Of Resin-based Composite Laminates And Honeycomb Board Structure

Thermal Protection for high speed aircraft has been an issue of great concern to the project in recent years, with the rapid development of composite materials and composite materials with metallic material unmatched excellent mechanical properties, the concern in thermal protection of aircraft is not limited to thermal shock and thermal problems of metal materials, but to the vibration and heat insulating of composite structure, so the research about dynamics and thermal properties of composites under thermal load presented a more high demand.Currently available studies on resin-based carbon fiber composite material structural variation with temperature is generally limited to static mechanical properties such as strength, stiffness variation with temperature research, few studies have addressed the dynamics properties of the composite structure in different temperature, which limits the research and development in the composite structures. The research about thermal insulation composite structures has been limited in finite element numerical simulation and theoretical solution, ignoring the impact of the distribution of real-world environment temperature and other factors on the results, lacking experimental study about thermal insulation composite structures limits the application and development of composite materials in the field of thermal insulation.In this paper, through the study of resin-based carbon fiber composite laminates and composite honeycomb panels under thermal load dynamics research and insulation properties, hoping to quantify the law of the influence of temperature about the mechanical properties of composite materials and the thermal insulation. For this reason, about laminates research in this paper: Firstly, the test method for heat mode and thermal performance laminates were studied; secondly, on the basis of the results of test measurements obtained using the method of finite element analysis of composite laminates thermal modal computing model is modified, and compared the error between test measurements and numerical simulation of thermal modal laminate calculations; Finally, theoretical calculations, numerical simulation and experimental methods are compared and analyzed to get the heat-insulating properties of laminated plate. Research on the honeycomb panels: Firstly theoretical calculation method to analyze the thermal performance of the honeycomb panels and discussed the impact of the rate of cellular radiation, secondly, numerical simulation method honeycomb panels insulation properties were calculated and compared with comparative analysis of the theoretical results; Finally, the numerical simulation method for heat honeycomb plate buckling analysis was calculated to analyze the influence of the thermal stress on the dynamic characteristics of the structure of honeycomb panels.
