摘要:
The present disclosure provides a composition for preparing a lightweight transparent composite, a method of preparing a composite using the same, and a composite prepared by the method. The lightweight transparent composite having excellent impact resistance, scratch resistance, weather resistance, and high hardness can be prepared by thermally curing a mixture of a glass fiber reinforcement having a refractive index of 1.4 to 1.6 and a curable resin having a deviation in refractive index of −0.005 to +0.005 from the glass fiber reinforcement. When the lightweight transparent composite is applied to transparent windows for automobiles, the lightweight transparent composite can be useful in enhancing fuel efficiency, achieving easier handling characteristics due to reduction in vehicle center of gravity, and improving juddering and dimensional stability even during car driving due to excellent hardness.
摘要:
A suspension fluid prepared by dispersing polyethylene oxide particles into a solvent including water and one or more types of compounds selected from the group consisting of ethylene glycol and propylene glycol, and a method for manufacturing the same. The phase-change suspension fluid can be a shear-thinning fluid showing a constant newtonian behavior in a low shear rate or low frequency region, but showing a non-newtonian behavior appearing as liquid-like suspension in a high shear rate or high frequency region due to viscosity decrease, and is capable of reversible phase changes by the vibration of a vehicle, and therefore, may provide effects of having advantages of a hydraulic bush in a low frequency region and also having advantages of a solid bush in a high frequency region.
