用玻璃纤维等增强，制成高性能复合仿木材料，推广使用这类仿木材料，不仅可得到美观实用的工艺品，工业和民用制品。同时可达到节省木材，保护森林和生态环境的目的聚氨酯仿木材料的性能特点为，应用领域，原料体系，制造工艺注意事项，指出这类材料利用了硬质聚氨酯结构泡沫塑料的优点，可制造仿木雕等装饰材料和结构材料。代替木材，具有良好的发展前景。
有少数仿木材料是高密度的混凝土，钢铁等，只是通过涂装或者模制工艺，使之外表具有木纹或树皮结构，作为装饰材料或栏杆等，不是真正意义上的合成木材，多数仿木材料可具有类似天然木材的密度，表面纹理，这些仿木材料大多具有微孔结构，例如微孔聚氯乙烯，微孔聚氨酯硬质泡沫塑料，有类似木材细胞结构，可代替天然木材使用。
The polyurethane rigid foam can be used to make liquid materials into models, which then will become imitation-wood workpieces with concavoconvex shapes. The imitation-wood sculptures can be produced in batch, and the molding technique is simple and the production efficiency is much higher than that of real wood sculptures. The polyurethane rigid foam can be enhanced to produce imitation-wood composite materials with high-performance by fiberglasses. It can not only produce beautiful and practical art wares, industrial products and civilian products, but also save woods, protect forests and the environment. It is a performance feature that the application area, the raw material system and maters needing attention of manufacturing techniques point out the advantage of making decorating materials and structural materials of imitation-wood sculptures by plastic foams of rigid polyurethane. The imitation-wood products have a good prospect. A minority of imitation-wood materials are the high-density concrete, steel and son on, which have wood grains and tree bark grains on their surfaces by coatings and molding techniques as decorate materials and handrails. They are not really synthetic wood. The majority of imitation-like materials have the similar density and grains as natural woods, and most of them have cellular structures, like micro-cellular PVC, micro-cellular polyurethane rigid foams, and the structures like wood cells, which can replace the natural woods.
