TITLE: Bio-Based Composite Sandwich Panel for Residential Construction
ABSTRACT: Bio-based composite is a green, environmental-friendly, and sustainable material. It has a very promising future in various construction applications due to its mechanic and environmental properties. This presentation will demonstrate the development of an innovative hurricane resistant composite sandwich roof panel made of all natural composite materials.
First, unit beams with different natural materials and sandwich construction types were fabricated and tested to tailor the bio-based composites, and to determine the proper sandwich construction type. With a prototype of roof panel designed, a scale beam model was then fabricated and tested to validate the viability of the application of bio-based composite for the proposed monolithic roof panel. Two web-core sandwich unit panels were also fabricated and tested to investigate the localized flexural stiffness and in-plane shear stiffness and strength of the proposed sandwich panel, and the viability of using them as diaphragms in residential construction,
The presentation will provide a lot of information on the design, manufacturing, and testing of composite structures through pictures. Related theoretical/analytical research results will be also covered, including the stiffness test method for shear deformable beams, orthotropic and shear deformable plate theory, and composite sandwich panel optimization with multiple design constraints etc.
BIO: Bo Hu received his Ph.D. in Civil Engineering from the University of Delaware, Newark in 2006. He received his Master of Bridge Engineering in 1998 and his Bachelor of Bridge Engineering in 1995 from Tongji University. His research has been focused mainly on bridge engineering, including bridge seismic design methods, probability-based seismic criteria determination, and behavior of complex bridge structural systems. His research paper “All Natural Composite Sandwich Beams for Structural Applications,” published in Composite Structures in 2004 is now the fourth most cited paper among articles published in the past five years for the journal. Currently he is the Lead design engineer for the segmental concrete box girder alternative, duties including post-tensioning designs, substructure designs, and detail designs etc.
