Is chopped glass fiber harmful to people?
The general concept of glass is hard and brittle objects, but it is not suitable for timber structure as its thread, strength is greatly increased and is flexible, with resin to give it shape can finally become excellent timber structure. Glass fibers increase in strength as their diameter decreases.
Classification of glass fibres:Glass fiber according to shape and length, can be divided into continuous fiber length, fiber and glass wool; according to the glass component, can be divided into non alkali, chemical resistance, high alkali, alkali, high strength, high elastic modulus and alkali resistant glass fiber etc..
As reinforcing materials, glass fibers have the following characteristics, which make fiberglass far more widely used than other kinds of fibers and develop far ahead of their characteristics:(1) high tensile strength and small elongation (3%).(2) high elasticity and good rigidity.(3) the elongation within the elastic limit is large and the tensile strength is high, so the impact energy is large.(4) for inorganic fiber, with non flammable, chemical resistance.(5) water absorption is small.(6) the scale stability and heat resistance are excellent.(7) good processability, can be used as stock, bundle, felt, weaving and other forms of products.(8) transparent and permeable to light(9) the development of surface treatment agents with good resin properties.
