An Experimental Study on Thermal Insulation Performance of Straw Wire Aircraft Sandwich Panel

Abstract:

Straw wire aircraft sandwich panel is a new type of composite slab which consist of straw insulation core lamped between two welded wire meshes. Diagonal shear connectors connect two wire meshes to form an integrated frame. The straw insulation core (also known as straw board) is prepared from cut straw agglutinated by magnesium oxychloride cement (MOC). In order to study thermal conductivity of straw board, multi-group models were quantitatively investigated by the CD－DR3030A thermal conductivity meter. Five parameters, including the water－cement ratio, cement content, straw gradation, straw length, wettability were considered in the test. The results show that the thermal conductivity of straw board samples is in the range of 0.08~0.12 w/m•k, which indicates that the straw board has a good thermal insulation property. And the water－cement ratio, cement content, straw gradation, straw length, wettability has remarkable effects on the thermal conductivity of straw board.
