A new imaging atmospheric Cherenkov telescope with a light-weight re ector has been constructed. Light, robust, and durable mirror facets of containing CFRP (Carbon Fiber Reinforced Plastic) laminates were developed for the telescope. The re ector has a parabolic shape (f/1.1) with a 30 m surface area which consists of sixty spherical mirror facets. The image size of each mirror facet is 0 .08 ...

The interference-fit size has a significant effect on the riveted lap joints of CFRP/Al alloy laminates. requirements for are different because strengthening heterogeneous materials. However, in riveting process alloys, laminates lead to poor structural strength requirements. Therefore, differently assembled molds designed acquire novel size, and tensile test is adopted evaluate their propertie...

• In-situ monitoring of transverse cracks and delamination for CFRP laminates under fatigue. Poisson’s ratio identifies whether early fatigue damage involves delamination. Interactive levels between are quantified. Correlation cumulative acoustic emission energy crack density. Ply-block size stress level effect on accumulation investigated during life laminates. Tension-tension tests different ...

Abstract The deformation and reconstruction of the composite propeller under static load in laboratory is studied so as to provide basic research for underwater deformed propeller. fiber Bragg grating (FBG) sensor proposed be used strain monitoring carbon reinforced polymer (CFRP) propeller, a algorithm structural curvature CFRP based on information presented. verified by using variable-thickne...
