| Abstract: | A crushed bamboo-mat composite has a high potential in exterior structural applications.The mechanical properties and dimensional stability of the bamboo composites,after an accelerated six wet-dry cycle and water boil tests,were studied.The results showed that the average modulus of rupture,modulus of elasticity,and shear strength of moso-bamboo composites,after the accelerated test,were no less than 120 MPa,13 000 MPa,15 MPa,respectively.The thickness swelling of the composite was no more than 5%.The mechanical performance of Neosinocalamus af finis bamboo composite,after the accelerated test,was even better. |
