Non-destructive testing of wood composites based on virtual instrument

A suit of wood-based composite nondestructive virtual instrument system based on Labview was designed in this paper. The sample of poplar Laminated Veneer Lumber was used to discuss the feasibility of the applications of virtual instrument in the wood-based composite nondestructive test. The main results are as follows: the longitudinal resonance elasticity modulus that was measured by virtual instrument can be the token of conventionality static elasticity modulus and FFT because they had prominent correlation under the level of 0.01.
