Hood adopting longitudinal-transverse reinforced rib structure and adopting RTM entire shaping technology and manufacturing method of hood

2015 
The invention provides a hood adopting a longitudinal-transverse reinforced rib structure and adopting an RTM entire shaping technology and a manufacturing method of the hood. According to the hood, carbon fiber textiles are used as a material, the textiles are fixed by adopting a hot melting type fixative, material preparation is performed according to the design of a paved layer, and the textiles are cut; the cut textiles are paved and pasted to a hood mold for preparing preforms, then the preforms are assembled and matched, the RTM entire shaping technology is adopted, under 2-10 bar pressure, resin is poured into the hood mold in which the preforms are paved, finally the resin is solidified and shaped in a curing furnace, and the shaped resin is demolded after solidification so as to obtain the hood with the longitudinal-transverse reinforced rib structure and adopting the RTM entire shaping technology. According to the hood disclosed by the invention, the precision of external dimensions of products can be guaranteed; the continuity of longitudinal and transverse reinforced ribs and a panel is guaranteed through the entire shaping technology method; besides, second cementation shaping is not needed, the apparent mass is better, the dimensions of the products are high in precision, the fiber volume fraction is high, the porosity is low, and the cost of the mold can be reduced through batch production.
