Introduction A renewable natural organic fibers act as reinforcing materials which are biodegradable and ecofriendly for the use of glass or carbon fiber and inorganic fillers.
It should be noted that the percentage of water absorption increased generally when more reinforcement materials are used which can be attributed to the hydrophilic nature of lignocellulose materials.

The results suggest that the Pb-free glass frit would be applicable for barrier rib materials in PDP.
A batch of each composition, consisting of high purity raw materials was well mixed with a mortar and a pestle.
Similarly the highest E and H value were obtained after sintering at 560 � for 1 h, therefore suggesting that this Pb-free glass frit would be suitable for barrier rib materials in PDP.

The experimental material is source-separated municipal solid waste.
As can be seen from the Fig.2, pyrolysis rate gradually increases with temperature rising from 450°C to 850°C, which means pyrolysis rate curves of different materials have the same variation tendency.
