Technical field
The utility model relates to a kind of composite plate, is specifically related to a kind of I shape sandwich composite board, and this I shape sandwich composite board is suitable for train inside door, door for Green Home.
Background technology
Along with industrial development, the application of lightweight product is more and more wider, and lightweight product, in meeting serviceability, can reduce energy consumption significantly, economizes on resources, and reduces cost, can also play vibration and noise reducing, and the effect such as increase the service life. Traditional sandwich structure material mostly is Metal Substrate sheet material, aspect lightweight enforcement, be designed to aluminium honeycomb more, high porosity porous metals sheet material is a kind of physical function and structure-integrated new engineering material of collecting, it has unique microstructure features, can bear larger plastic deformation, but this aluminium honeycomb sheet metal heat insulation effect is poor, and metal is than great, slightly inadequate aspect lightweight enforcement.
Chinese patent CN201120294908.X, using carbon fibre composite as upper and lower panel, taking closed pore rigid foamed plastics plate as laminboard layer, builds a kind of light-weight multi-layer structural panel, can meet aeronautical product demand. But carbon fiber is expensive, rigid foamed plastics plate complicated process of preparation, is not suitable for general promoting the popularization use. Chinese patent CN200920109035.3 has reported a kind of a kind of concave-convex adapted composite boards of structural design such as special tongue and groove, reinforcement keel, L-type joint angle that utilize, although saved welding, riveted joint process, but essence is still physical connection, and this structure is loaded down with trivial details, and coupling mechanism force also has much room for improvement. Chinese patent CN201110220912.6 has reported three kinds of pyramid lattice sandwich structures that Different Preparation condition obtains, make the design of pyramid fuse mould therefor complicated, technological operation is cumbersome, and pyramid fuse and panel adopt some contact form, contact area is less, intensity is lower, and manufacturing cost is high, is not suitable for a large amount of production and commercialization application.
Utility model content
The purpose of this utility model is that a kind of intensity is high, quality is light in order to provide, avoid the I shape sandwich composite board of physical connection defect simultaneously, panel and I-shaped reinforcing rib structure are actual to be contacted for face, with contact and physical connection is compared, greatly increase adhesive strength, avoided again the weld seam, the connecting sewing problem that in welding, riveted joint process, produce simultaneously.
For achieving the above object, the technical solution of the utility model is: a kind of I shape sandwich composite board, comprise upper face, lower face and laminboard layer, between upper face and lower face, be provided with laminboard layer, laminboard layer is made up of I-shaped reinforcement and flame-retardant foam filler, and the distribution density of I-shaped reinforcement between upper face and lower face is 3-10/dm2, wherein upper face and lower face are made up of compound resin, comprise matrix and reinforcement.
Preferably, described matrix is that unsaturated polyester resin, epoxy resin, acrylic resin, phenolic resins or melamine resin form; Described reinforcement is fiber cloth, and wherein fiber cloth is glass fibre, carbon fiber, aramid fiber or textile sheet.
Preferably, described I-shaped reinforcement is that galss fiber reinforced resin obtains by pultrusion molding process.
Preferably, described flame-retardant foam filler is fiber-reinforced composite resin, and fiber-reinforced composite resin injects upper face, lower face and I-shaped reinforcement around.
Preferably, in described flame-retardant foam filler, add flame retardant aid, described fire retardant is phosphorus flame retardant, and addition is 10%-35%.
Adopt after technique scheme, the beneficial effects of the utility model are: the utility model cost is low, intensity is high, quality is light, meets lightweight feature, and the defect while simultaneously avoiding physical connection is suitable for door for train inside door and Green Home.
