Description
Technical field
The utility model relates to a kind of multifunctional composite stair treads.
Background technique
Glass reinforced plastic alias fiberglass reinforced plastics is commonly called as FRP(Fiber Reinforced Plastics), i.e. fiber
Enhance composite plastic.It is divided into glass fiber reinforced composite plastics (GFRP) according to the fiber difference of use, fibre reinforced is compound
Plastics (CFRP), boron fibre enhance composite plastic etc..
It is to make base using glass fibre and its product (glass cloth, band, felt, yarn etc.) as reinforcing material with synthetic resin
A kind of composite material of body material.Fibre reinforced composites are made of reinforcing fiber and matrix.Fiber (or whisker) it is straight
Diameter very little, generally at 10 μm hereinafter, defect is less and smaller, it is fragile material, easily that breaking strain, which is about within 30/1000ths,
Damage is broken and is corroded.For matrix for fiber, intensity, modulus will be much lower, but can withstand big answer
Become, often there is viscoplasticity and elastoplasticity, be toughness material.
Since used resin variety is different, there is the title of organic toughened glass, fiber glass epoxy, phenolic fiberglass reinforced plastics.
Light and hard, non-conductive, high mechanical strength recycles less, corrosion-resistant.Can replace steel manufacture machine part and automobile,
Ship housing etc..
The advantages of glass reinforced plastic, is: high-strength light.Relative density is between 1.5 ~ 2.0, only the 1/4 ~ 1/5 of carbon steel, but
Tensile strength but approaches, even more than carbon steel, and specific strength can be compared with high-grade alloy steel.Therefore, aviation, rocket,
Space vehicle, high-pressure bottle and in the product application that other need to mitigate self weight, all have brilliant effect.Certain epoxies
Stretching, bending and the compressive strength of FRP can reach 400Mpa or more.It is corrosion-resistant.FRP is good anticorrosive material, to atmosphere,
Water and the acid of general concentration, alkali, salt and a variety of oils and solvent have preferable resistivity.Have application to chemical anticorrosion
Various aspects are replacing carbon steel, stainless steel, timber, non-ferrous metal etc..Good electrical property.It is excellent insulating materials, for making
Make insulator.It remains to protect good dielectricity under high frequency.Microwave transparent is good, is widely used in radome.Hot property
Well.FRP thermal conductivity is low, is at room temperature 1.25 ~ 1.67kJ/(mhK), and only the 1/100 ~ 1/1000 of metal, it is excellent
Heat-insulating material.In instantaneous superhigh temperature, it is ideal thermal protection and ablation resistant material, space vehicle can be protected to exist
2000 DEG C or more are born washing away for high-speed flow.Designability is good.(1) it can according to need, neatly design various structures
Product can make product have good globality to meet requirement.(2) material can sufficiently be selected to meet product
Performance, as: can be designed that corrosion resistant, resistance to TRANSIENT HIGH TEMPERATURE, have that especially high-intensitive, dielectricity is good on product direction,
Etc..Craftsmanship is excellent.(1) molding work can be neatly selected according to the shape of product, technical requirements, purposes and quantity
Skill.(2) simple process, can be with one-pass molding, and economic effect is prominent, especially to it is complex-shaped, be not easy the few production of molding quantity
Product, its more prominent technique superiority.
The shortcomings that glass reinforced plastic is: elasticity modulus is low.The modular ratio timber of FRP is twice big, but smaller than steel (E=2.1E5)
10 times, therefore rigid deficiency is often felt in product structure, it is easily deformed.It can be made shell structure, sandwich, can also lead to
It crosses high modulus fibre or does the forms such as reinforcing rib to make up.Long-term temperature tolerance is poor.General FRP cannot make for a long time at high temperature
With general purpose polyester FRP is just decreased obviously in 50 DEG C or more intensity, general only used below at 100 DEG C；Universal epoxy FRP exists
60 DEG C or more, intensity decreased significantly.But it can choose fire resistant resin, long-term operating temperature made at 200 ~ 300 DEG C to be possible
's.Aging phenomenon.Aging phenomenon is the common defects of plastics, and FRP is no exception, ultraviolet light, dust storm sleet, chemical mediator,
It is easy to cause performance to decline under the effects of mechanical stress.Shear strength is low.Interlaminar shear strength undertakes by resin, so
It is very low.Interlayer adhesion can be improved by selection technique, using the methods of coupling agent, most importantly in product design
When, it avoids cutting interlayer as far as possible.The production method of glass reinforced plastic substantially divides two major classes, i.e., wet process contact-type and dry method pressurization at
Type.Such as divide by process characteristic, there is hand pasting forming, laminated into type, RTM method, ironing, compression molding, Wrapping formed etc..Hand paste
Molding includes hand molding, pressure bag method, gunite, wet paste low-pressure process and without mould hand molding again.
Utility model content
Technical problem to be solved in the utility model is the above-mentioned deficiency in the presence of overcoming the prior art, and provides one
It kind is made with glass-reinforced plastic material, it is more that intensity is high, at low cost, the service life is long, safety is higher, environmentally protective, using effect is good
Functional composite material stair tread.
The purpose of this utility model is achieved through the following technical solutions: a kind of multifunctional composite stair tread, packet
Multiple transverse parts and longitudinal direction portion are included, transverse part and longitudinal direction portion form multiple hollow portions, and transverse part and longitudinal direction portion are mutually in 90 ° of intersections
