Glass fibre is a kind of inorganic non-metallic material haveing excellent performance, strong, anticorrosive with good insulating, heat resistance
Good, many merits such as mechanical strength height of property, but shortcoming is that property is crisp, and wearability is poor.It is using glass marble or discarded glass as original
What material was manufactured into through techniques such as high temperature melting, wire drawing, doff, woven fabrics, a diameter of several microns of monofilament are micro- to twenties
Rice is equivalent to the 1/20-1/5 of a hairline, is all made of per bundle fiber precursor hundreds of even thousands of monofilament.
Glass fibre is typically used as the reinforcing material in composite material, and glass fibre to the humidifications of plastics very
Significantly, this is because the modulus of glass fibre in itself is very high, and glass fibre is grown along internal body, is expanded by external force during external force
It dissipates and is improved with entire material, shock resistance and bending property.
Specifically, when composite material is acted on by external force, either cross force or longitudinal force are either drawn
Stretch or extruding force, composite inner can all generate a stress.When being added with glass fibre in composite material, stress
Disperseed well by interface binding power excellent between matrices of composite material phase and glass fibre, make the fiber haveing excellent performance
Most of stress is assumed responsibility for, so as to improve the comprehensive performance of composite material.Has experimental result it can be shown that working as composite material
During by power along glass fibre longitudinal direction, stress concentration is generated at the both ends of glass fibre, and exist around glass fibre should
Power is less than the elliptical region of mean stress, and such glass fibre is reached by reducing the mean stress of matrices of composite material phase
Enhancing effect is arrived；When composite material is by power along glass fibre transverse direction, matrices of composite material is sent out due to the influence of external force
Raw deformation, the modulus of the modular ratio glass fibre of matrix is small, and the two combination is more close, thus glass fibre constrains
Matrix deformation and load is reached on glass fibre, such load is just by matrix and glass fibre shared, due to glass
The rigidity and intensity of fiber are all far above matrix, therefore the addition of glass fibre improves the mechanical property of material.

Under：
Ca(C17H35COO)2+2H++2X-→CaX2+2C17H35COOH
Antioxidant is broadly divided into two major class, and one kind is primary antioxidant, mainly Hinered phenols antioxidant, is moulded by capturing
The free radical that generates in material degradation process and long duration plays antioxidant effect；One kind is auxiliary antioxidant, mainly phosphorous
Esters of gallic acid, monothioester kind antioxidant, generated peroxide of further being degraded by decomposition plastics is so as to reach anti-oxidant
Purpose, it is main that hot-working stability is provided.Primary antioxidant and auxiliary antioxidant are used in conjunction with that synergistic effect can be generated.
