The testing materials are four low density closed cell polyurethane foams and one typical active military life jacket floating material NBR/PVC foam.
Experimental Materials.
Table 1 lists the primary parameters of the five test materials.
The results also show that the polyurethane foams are a good energy absorbing materials.

The most important characteristic of SLS is that a wide range of materials can be used in SLS, for example wax powder, PS, ABS, PC, PA and metal powder etc.[3], but high price of materials is the bottleneck to constrain SLS application widely, so reducing the cost of materials has always been a research focus in this area.
Wood-Plastic Composites (WPC) is green biological materials, it has many advantages such as good mechanical properties, high hardness, anti-aging, dimensional stability, easy to color, with wood texture and also recycled, the most important advantage is low-cost[4].
It indicates that wax shows good bonding with WPC because both of Co-PES hot-melt adhesive powder and alkalized wood powder are non-polar materials，the surface is very smooth.

It was introduced by adding 0.05-1% Al-powder as the initiated materials of geopolymers to react with water in those materials and promote hydrogen gas inside specimens.
Introduction Cement is one of most important construction materials.
The pozzolanic materials normally rich in silica and alumina such as fly ash, blast-furnace slag, rice husk ash and metakaolin are commonly used as starting materials for geopolymer making [5].
Locally available material such as metakaolin is used as mainly pozzolanic materials of porous geopolymer.
