Depend on your research interest. However I suggest you to read these two articles recently published:
1. Akampumuza, O., Wambua, Paul. M., Ahmed, A., Li, W. and Qin, X.-H. (2017), Review of the applications of biocomposites in the automotive industry. Polym. Compos., 38: 2553-2569.
Hi Linto, good to hear! Have you any experience with bio/natural composites? There's plenty of research to be done in bistable natural composites, just that I don't have time to do it so it'd be great to find some help
As we know that Bio composites is one of the emerging areas in polymer science which got attention for use in various applications ranging from automobile to the building industries. However, some gaps are still there which need to be narrowed down.
1. Thermal aging tests PLA biocomposites with and without compatibilizer were deteriorated due to the presence of gaps between components and shorter PLA molecules as compared to neat PLA. Much work is not highlighted on this issue.

2. Gaps between jute/PP due to the thermal shrinkage of the matrix have been filled by the swelled fiber after 14 days of water immersion conditioning.Fibre–matrix interface gaps which is caused by shrinkage and incomplete wetting of the fibre-resin interface during composite processing.)

3. Why the water molecules diffuse into the micro gaps between polymer chains. The water molecules can migrate into the voids and gaps at the fibre–matrix interfaces. How to sort out this issue is another demanding research. They can raise the swelling level due to water absorption possibilities are more there. How to resolve this issue is also to be considered.
4. Alkalinity effect ratio which hampers the curing effect in building fiber reinforced material downing compression strength value.
There are many research gaps related to the development of biocomposites, which are materials made from biodegradable or renewable resources that are reinforced with fibers or other reinforcement materials. Some potential research areas for the development of biocomposites include:
Development of new biodegradable polymer matrices: Many biocomposites are currently made using synthetic polymers, such as polylactic acid (PLA) or polyhydroxyalkanoates (PHAs), as the matrix material. However, there is still a need to develop new, more sustainable biodegradable polymers that can be used in biocomposites.
Improvement of the mechanical properties of biocomposites: Biocomposites often have lower mechanical properties, such as strength and stiffness, compared to synthetic fiber reinforced polymer composites. Research is needed to improve the mechanical properties of biocomposites through the optimization of fiber-matrix interactions, fiber orientation, and other processing parameters.
Development of new natural fiber sources: Natural fibers, such as flax, hemp, and bamboo, are often used as reinforcement in biocomposites. However, there is a need to identify new, more sustainable sources of natural fibers that can be used in biocomposites.
Investigation of the environmental and health impacts of biocomposites: Biocomposites are often marketed as more environmentally friendly and sustainable alternatives to synthetic composites. However, more research is needed to understand the full environmental and health impacts of biocomposites throughout their lifecycle, including production, use, and disposal.
Development of new processing techniques for biocomposites: Many biocomposites are currently produced using traditional processing techniques, such as compression molding or injection molding. However, there is a need to develop new, more efficient and sustainable processing techniques for biocomposites.
These are just a few examples of the many research gaps related to the development of biocomposites. There is still much to be learned about these materials, and
