At present, the composite materials used in automobile manufacturing are mostly fiber-reinforced, or resin-based composite materials reinforced by woven fabrics and non-woven fabrics. Vehicles are exposed to external vib...
The sandwich material for composite sandwich structure is mainly: hard foam, PMI foam, honeycombs and light wood three categories. The hard foam mainly has polyvinyl chloride, polyurethane, polyetherimide, and acrylonitr...
PMI foam material is the current development of polymer foam core material. It has many advantages such as low density, excellent high temperature resistance, low dielectric constant and dielectric loss, good fatigue res...
PMI foam is a material that is currently developing in polymer foam core, has a small density, excellent high temperature resistance, low dielectric constant, and better fatigue resistance, and high resistance to voltage...
When the length of the blade increases, the increase in quality is faster than the energy of energy, as the quality increases and the cube of the blade length is proportional, and the strength of the electric energy gene...
1. The grassroots wall should remain smooth and strong, while vertical, in line with my country's wall construction specifications. In summer, the construction of core material foam should take good sun protection measur...
