Study on mechanical properties of wood plastic composites Huang fang Eastern Liaoning University, Chemical Engineering and Materials Science, Liaoning Dandong 118000 3x.931@163.com Key words: composite material; mechanical properties; research Abstract.Composite material has many excellent properties, current, receives special attention was paid to its mechanical properties.
Composite materials are often called fiber ( or other dispersed phase) reinforced composite materials.
Experiments show that, the ratio of raw materials on the properties of the composite materials affected greatly.
This shows that rely on increase the dosage of solvent to improve the mechanical properties of materials is limited.

Introduction Iron disilicide (β-FeSi2) is a potential candidate for thermoelectric materials because of its abundance as a raw material, high Seebeck coefficient, large working temperature range, good resistance to oxidation, and non-toxicity.
Doping of β-FeSi2 with metals, e.g., Co and Mn, to produce n-type and p-type materials, respectively, is aimed at improving the Seebeck coefficient and electrical conductivity [1].
It was proved that FAPAS is a benign and rapid synthesis method for β-FeSi2 thermoelectric materials.
Conclusions (1) Mechanically activated powder mixtures of Fe and Si were applied to fabricate FeSi2 and FeSi2-0.1wt%Cu bulk thermoelectric materials by FAPAS process.

The hardness values of these abrasive materials are shown in Table 2.
Effects of Mixed Abrasives In the lapping process, the machining effect is often dissatisfactory when one kind of abrasive is used to machine some difficult-to-machine materials.

Fibre composite materials have become an important target for the solution of degradation problems in conventional structural materials such as steel, wood and concrete [1].
GFRP materials will loss the strength when the temperature exceeds 600 C0 as shown in Fig. 5 and Fig. 6.
The materials mechanical properties are shown in Table 1.
