Dependability of Composites Construction
Original language description
Polymer composite sandwich panels (PCSP) are used in many sectors of industry, particularly in aerospace and defense industry and in great scale also in public transport industry. Sandwich panels consist of two facing skins and the core. Products of all industry sectors have to meet requirements on their dependability. This research paper deals with a proposal of the most appropriate methodology for dependability testing of PCSP´s products used in transport industry. Dependability is a global concept that includes terms of availability, reliability, durability, maintainability, supportability, etc. The experiment have shown S-N curves with damages and without damages of PCSP. An important part of dependability is to find limit states of studied object, which are for PCSM characterized by fiber cracking and (core) delamination. Dependability evaluation consists of analysis and tests. For every test, it is necessary to develop the test plan. Facing skin components of the sandwich panels may particularly be damaged. There are several methods of non-destructive testing, which can be used to determine the damage of facing skins of sandwich panels. Infrared thermography (IRNDT) is one of them. IRNDT utilizes thermo-physical properties of the materials, including thermal diffusivity.
