Introduction Shape-memory materials are stimuli-responsive materials.
The shape-memory effect is not related to a specific material property of single polymers, it rather results from a combination of the polymer structure and the polymer morphology together with the applied processing and programming technology [1].
The shape-memory LC epoxy resin may be used in deployable space structures or other high-performances equipments as composite materials in the near future.

Therefore, the chitosan or its hybrid materials with other natural or synthetic polymers are extensively studied for the applications as artificial skins, cartilages, or bones.
Thus, many investigations have already been made to develop a bioactive chitosan system for the application as bone restorative materials through the hybridization with chitosan and calcium phosphates.
However, there has been no report to use IPTS alone without tetraethyl orthosilicate for giving bioactivity to originally non-bioactive materials.
Therefore, some surface modification, which can give nucleation sites for the apatite crystals, is required for using chitosan as a bioactive bone repairing materials.

This research utilizes natural fibre (kenaf fibre) which is much cheaper compared to glass fibre in attempt to reduce the cost of pultruded composites which usually produced using glass fibre and hence becoming more competitive alternative materials for conventional materials such as galvanized steel.
Next, the mechanical properties of biodegradable composite materials using kenaf fibres as a reinforcement and Polyester resin as a matrix were investigated.

Introduction As a kind of non-ferrous metal material with excellent performance, aluminum and its alloy materials are widely used in aerospace, automobile manufacturing, defense industry, electronic products and other fields [1, 2].
The environmental friendliness of material preparation is becoming more and more important, and more environmentally friendly materials should be used for the encapsulation treatment.
