        玻璃 reinforcement fiber plastics is what?

         glass fiber reinforcement plastics, is types product types more, property can 各别, applications composite/compounding material. it is combined formed resin and glass fiber composite/compounding process, made as formed types function type new type material.

         glass fiber reinforcement plastics features:

        (1) corrosion resistant property good: FRP is good corrosion resistant material, for/regarding large gas; water and generally concentrated degree acid alkali; salt and multiple type and solvent agent has relatively good resistant force, already by widely used in chemical industry anti 腐 各 方面. positive in carbon 钢;不锈钢;木材; has color metal and other material.

        (2)质 light high strong/high: FRP versus for density in 1.5~2.0 between, has carbon 钢 1/4~1/5但 is tensile strength 却接近甚至 ultra- carbon 素钢, strong/high degree can and high grade alloy versus ratio, by 广泛 应 used for aviation aerospace; high pressure container and other need decrease light heavy products in.

        (3) electrical property can good: FRP is excellent insulation material, used for manufacturing insulation 体, high frequency lower still can maintain good.

        (4) thermal properties good: FRP conductive rate low, room temperature lower is 1.25~1.67KJ has metal 1/100~1/1000 is excellent 良 绝 hot material. in ultra-high hot lower, is hot and resistant 烧蚀材 material.

        (5) process property can excellent 良: can according to product selection molding process process simple can one-time molding.

        (6) can design property good: can according to demand separation selection material meet/satisfy product property can and structure and other requirements.

        (7) elastic property modulus low: FRP elastic property modulus ratio large 2倍但 ratio small 10倍, therefore in product structure in to rigid property 不足, easy deformation. solution methods, can formed thin housing/shell structure;夹层 structure can through high modulus fiber or add strong/high 筋形式 弥补.

        (8) long resistant temperature property 差: generally FRP不 can in high temperature lower long use, general purpose polyester resin FRP in 50 degree above strong/high degree obvious decline.

        (9) aging phenomenon: in outer 线;风沙雨雪; chemical 介质; machine force and other function lower easy property can decline.

        (10)层间剪切 strong/high degree low: 层间剪切 strong/high degree is resin 承担, therefore relatively low. can through selection process, use coupling agent and other methods improve/increase adhesion force, in product design amount make 层间受剪.

         glass fiber reinforcement plastics advantages:

         glass fiber reinforcement plastics heat resistant temperature degree ratio add glass fiber (GF) high very more, especially is nylon type plastics

         glass fiber reinforcement plastics shrinkage rate low, rigid property high.

         glass fiber reinforcement plastics 不会应 force cracking, meanwhile, reinforcement fiber plastics impact resistant property can improve/increase very more

         glass fiber reinforcement plastics strong/high degree high, 如: tensile strength, pressure shrink strong/high degree, flexural strength, very high.

         glass fiber reinforcement plastics due to its it additives add 入, make glass fiber reinforcement plastics property can decline very more, large separation material can 点燃, is types flame retardant material.

         glass fiber reinforcement plastics disadvantages:

         glass fiber reinforcement plastics due to glass fiber (GF) add 入, make plastics formed transparent, add glass fiber (GF) front is transparent.

        塑 glass fiber reinforcement plastics ratio add glass fiber (GF) plastics tough property reduce, property increase;

        塑 glass fiber reinforcement plastics due to glass fiber (GF) add 入, has material melt viscosity increase large, flow property 变差, injection molding pressure ratio add glass fiber (GF) need increase very more, is positive injection molding, has reinforcement plastics injection molding temperature degree need ratio add glass fiber (GF) front improve/increase 10℃-30℃.

         due to glass fiber (GF) and additives add 入, glass fiber reinforcement plastics wet property can large add strong/high, pure plastics water 也会变 吸 water, therefore, injection molding need dry.

         glass fiber reinforcement plastics in injection molding process in, glass fiber (GF) can plastics products surface, make products surface very coarse 糙, 斑斑点点. is relatively high surface quality, most good injection molding use mold temperature machine add hot mold, make plastics polymer/macromolecule products surface, can to pure plastics appearance quality.

         glass fiber reinforced rear, glass fiber (GF) is hardness very high material, additives high temperature rear is property very large gas 体, for injection molding machine screw and injection molding mold abrasion loss and very large, therefore, production use this category of material mold and injection molding machine 时, need attention/notes equipment surface anti 腐处理 and surface hardness 处理.
