Acoustic Emission (AE) is a useful non-destructive evaluation method to detect the damage of materials in real time.
In addition, it is very difficult to set the threshold level optimally before measurement, especially in inexperienced materials or structures.

Introduction Nowadays, Ordinary Portland cement (OPC) concrete is the most popular and widely used building materials, due to its availability of the raw materials over the world, its ease for preparing and fabricating in all sorts of conceivable shapes.
However, due to the restriction of the manufacturing process and the raw materials, some inherent disadvantages of OPC are still difficult to overcome.
WPSA compose of some oxide materials derived from inorganic compounds that remain after burning.

Introduction Lignocellulosic materials such as poplar wood have recently gained attention as feedstock for bioethanol production due to the limited supply and high cost of lignocellulosic sources from food such as corn [1–4].
Trichoderma reesei is widely used to produce cellulases for the conversion and utilization of lignocellulosic materials [5].
Materials and methods Fungal strain The parent strain, T. reesei Rut C30 (ATCC-56765), was previously stored by the Ministry of Forestry Bioethanol Research Center at the Central South University of Forestry and Technology (Changsha, China).

Although employing stiff and light materials such as composites leads to increase in speed, structural damage is still significant [1].
Furthermore, the introduction of composite materials in marine architecture, such as fast marine crafts, has brought new types of operational failures in panels.
In contrast to metallic materials, when the design makes use of composite materials, different types of cracks can appear such as delaminations.
