Automobile lightweight fiber reinforced composite materials are key.
Automobile lightweight, is to ensure the strength of the car and under the premise of safety performance, reduce the curb weight of the car, as much as possible so as to improve the power performance of vehicle, reduce fuel consumption, reduce exhaust pollution.Auto industry, as it were, it is not easy to implement stringent emission regulations, there is a clear need for a more lightweight solution, with the progress of technology, the realization of lightweight are implemented step by step, which are also a good chance of plastic industry.And fiber reinforced polymer (FRP) is made by enhanced fiber material, such as glass fiber, carbon fiber, aramid fiber, etc., and after winding substrate material, moulding and pultrusion molding process and the formation of the composite material, has the characteristics of light weight, high strength, overloading, the realization of auto lightweight plays an enormous role.

Fiberglass Boats Maintenance-----Part 1
Fiberglass Boats Maintenance-----Part 1
Fiberglass boats currently has basically occupied the small boat market, and it is very popular in companies and passengers with advantages of light weight, high strength, beautiful shape and a variety of colors.
However, for a long time, fiberglass boat maintenance has not been paid to much attention. Most manufactures don't introduce maintenance tips in the product manual and user instructions. Many users lack of fiberglass material, performance and other characteristics, so many people believe that fiberglass boats don't need any maintenance because they are high strength, never rust and have gel-coat layer of protection. That caused a lot of fiberglass boats service life is shorten due to lack of maintenance.
Glass fiber reinforced plastic is made of synthetic resin as matrix and glass fiber as reinforced material. It has similar strength with steel material, and it has superior performance of water resistance, corrosion resistance, smooth surface finish and beautiful appearance and integral forming. But it also has some shortcomings, such as small stiffness, poor resistance to abrasion. In particular, there are many factors affecting product quality (such as the quality of raw materials, technical quality, production conditions and environmental factors, etc.), which makes the difference in the quality of similar products.
Compared with steel and wooden boat, FRP boat has the characteristics of less maintenance, which is decided by the superior performance of the glass fiber reinforced plastic. However, glass fiber reinforced plastic likes all materials, there is also a problem of aging, but the process is slower. Even in the boat surface applied the gel coat resin form a protective layer, due to the thickness of only 0.3-0.5mm, in often friction and erosion environment will damage and the thinning. So fiberglass products need less maintenance rather than no maintenance, proper maintenance can not only maintain the beautiful appearance, but also to extend the life of fiberglass boats.

Reflector Lamp Production - BMC Injection Molding
At present, we generally use parabolic reflector lamp and free curved surface reflector, the traditional stamping process has been unable to meet our requirements, so thermosetting plastic BMC injection is usually applied to the production.
Fiberglass BMC as a kind of glass fiber reinforced unsaturated polyester thermosetting composite material, since the late 1950s,it has attracted much attention, and has been developing rapidly, and commonly used thermosetting plastic, BMC molding technology including compression molding, transfer molding and injection into three methods, which injection molding has the advantages of high degree of automation, short molding cycle, work piece surface quality, the molding process of good.
BMC is unsaturated polyester resin, chopped glass fibers, fillers and various additives such as initiating agent, inhibitor, in the release agent (generally do not have a thickening agent) with a fully mixed material group.
BMC in the manufacturing process is divided into two steps. The first step is with high shear mixer for preparing resin, causing agent, pigment, release agent and filler resin paste and above all group divided in the filler should be added first, and other group mixing evenly, then slowly and fill filling agent to evenly dispersed. The second step mixing slurry pour Z shaped cutter feeding machine or planetary mixer mixing machine, and adding short glass fibre, and then mixing 10-15 minutes can be out of the material, material group further extruder crowded into a rope or a small column.
