Abstract:
The thesis probed into the factors influencing the mechanical properties of composite material,such as fiber length,dosage of rock wool,density,resin content,temperature of hot pressing and hot pressing time,etc.when using rock wool and wood fiber to make wood fiber-rock wool composites.The study shows that it is feasible to make wood fiber-rock wool composites by blending rock wool and wood fiber.The length of wood fiber,density of the products,dosage of rock wool are the main factors influencing the mechanical and fire-retardant properties of composites.With the increase of wood fiber length,the static bending strength of products increases and the internal bond strength decreases.When density increases,the mechanical properties of the products heighten linearly.When the dosage of rock wool increases,the mechanical properties of products weaken linearly and the fire-retardant performance of the products heightens linearly.Within the range of parameters which are selected for the experiment,the influence of resin content,temperature of hot pressing and hot pressing time on the mechanical properties and fire-retardant performance of the products is not obvious.
