Normal voltage rises sharply in the inner layers of unidirectional material compared to layers with cross-reinforced materials.
Analysis of stress-strain state of naturally twisted rods of composite materials allows revealing features of the reinforced material in a flexural-torsional coupling.
When stretched, even for weakly twisted bars with large relative thickness when using composite materials on the edges may arise compressive (tensile) stress, which is undesirable for reinforced materials.

This paper summarized the research status methods and distinguishing features of fireproof materials in China which would make progress to our research on fireproof materials.
According to the literature on fireproof materials recently, the research of fireproof materials divide into three directions approximately: the classes of fireproof materials, the principle of fireproof materials and the special applications of fireproof materials in different fields[1]. 1.1 The research on class of fireproof materials classified various materials which include HPL(Pecorative high-Pressure Lcminate), fire resistant doorsets, fire-resisting wood windows, fire roller shutter, Anti-fire Glass, fireproof storage box, fire-retardant coatings and fire-proof sealing materials. 1.2 The research on the principle of fireproof materials analyzed the flameproof procedures based on principle and prevention measures for preventing even holding back fires though experimentations and theoretical analysis[2]. 1.3 The applied research of dedicated fireproof materials studied the application of fireproof materials in different situation.
The production of these materials would be green environmental.
