Flaws and shortcomings

Low modulus of elasticity

The elastic modulus of FRP is twice as large as that of wood, but 10 times smaller than steel (E=2.1E5). Therefore, it is often insufficient in rigidity and easily deformed in the product structure.

It can be made into a thin shell structure or a sandwich structure, and can also be compensated by high modulus fibers or reinforcing ribs.

Poor long-term temperature resistance

Generally, FRP can not be used for a long time at high temperature. The strength of general-purpose polyester FRP is obviously lower than 50 °C, generally only below 100 °C; general-purpose epoxy FRP is above 60 °C, the strength is obviously decreased. However, it is possible to select a high temperature resistant resin so that a long-term operating temperature of 200 to 300 ° C is possible.

Aging phenomenon

Aging is a common defect of plastics. FRP is no exception. It is easy to cause performance degradation under the influence of ultraviolet light, sand, rain, snow, chemical medium and mechanical stress.

Low interlaminar shear strength

The interlaminar shear strength is borne by the resin and is therefore very low. The adhesion between layers can be improved by selecting a process, using a coupling agent, etc., and most importantly, avoiding shearing between layers during product design.

Deep Well Plate

Deep well Plate is an ideal product for sample storage, we have many types of 96 Deep Well Plate, such as 0.5ml elution plate, 1.2ml square well V bottom plate, 2.0ml round well U botttom plate for Hamilton and Nunc machines, 2.2ml square well V bottom and 2.2ml square well U bottom. They can be sterilized under high press, and keep the shape for 20 minutes even the temperature arrives at 121℃,All these characteristics set a new standard for the laboratory.
